How do environmental factors influence housing design?

Actuators for operation in harsh environments, such as high or low temperatures, corroding chemicals, or vibrations, must be designed accordingly.

Industrial actuators include several features that help ensure their durability and the highest possible Ingress Protection rating (IP69K): aluminium housings, coated PCBs to protect the electronics, polished inner tubes to reduce the moisture ingress, specially selected cork sealings for harsh environments and dust explosive environments (ATEX and IECEx).

The surface of aluminium housings for LINAK® industrial actuators is resistant to corrosion, and cables are easily replaced without compromising the actuator’s IP rating. In certain cases, where an actuator is in touch with extremely corrosive materials or exposed to vapours, such as fertilizers and ammoniac, we recommend choosing an anodised housing, as it comes with a special coating.

How do spindles influence/impact actuator efficiency?

The efficiency of an actuator is directly related to the motor, the gears, and the spindle, and how these components work together.

Because of the spindle and its shape, an electric actuator will always provide the same output power, regardless of the load applied, whereas a hydraulic or pneumatic system will provide a varied efficiency between push or pull. Even though the pressure in such a system is the same, the inside area through which the oil or air travels will be smaller when running inwards in pull, and the efficiency relatively lower than in push.

Regardless of the load, an electric actuator can run at the same speed both in push and pull.

With the actuator output power available, you can choose to move a high load at a low speed, or the other way around. If you multiply the load with the speed, you will get the output power required for the right movement – this will give you a good indication which actuator model you need. With a LINAK® actuator you can choose between different gears and spindle pitches to get the ideal solution.

There are many different types of spindles and spindle nuts for electric linear actuators, and they are always selected based on the required load and performance of an actuator. For example, for lifting heavier loads, the nut must be longer to better distribute the load between the threads in the nut.

Spindle geometry must be considered to obtain an optimal efficiency output of a spindle. Trapezodial, high profile and low profile are examples of spindle geometry used for LINAK industrial actuators.

How do you find the actual B10 Life of an actuator?

The B10 Life value is found by testing groups of actuators at a certain load.

In real life however, many applications have load profiles, which means that the actuator has varying loads throughout the stroke.

In these cases, we need to determine the equivalent load to find the B10 Life.

You can learn how that is done in this video.

How does a DC motor work?

The functionality of a DC motor is based on the principle of induction. Induction is the current that is generated inside the magnetic field, when the inductor or magnetic field rotates.

When current flows through the armature coil, an electromagnetic force is induced, and the coil begins to rotate.

When the coil reaches the opposite magnetic field, the commutator rings will touch the power source of the opposite polarity. This means that the electromagnetic pull will change direction, and the coil will continue to rotate in the same direction.

How does actuator housing design ensure actuator performance?

The design of actuator housings is highly influential when it comes to the performance of the actuators: The back fixture can either be welded on the housing itself or be attached as a separate stainless-steel back-fixture.

In either case, the push/pull forces created when moving a load will travel differently through the actuator and its housing. Actuators handling higher loads are usually designed with a separate back fixture to ensure that the housing is not directly exposed to the force. Higher loads in combination with vibrations can damage the housing and reduce the actuator’s ingress protection.

What are the benefits of knowing the B10 Life of your actuator?

The B10 Life values can help you design your application. At LINAK®, the values offer a lifetime estimate for electric linear actuators used in an application, such as off-highway vehicles, industrial automation applications, and agricultural machinery. B10 life not only helps in selecting which actuator to use – it can also be an invaluable tool for predicting maintenance.

What are the main differences between plastic and aluminium housings?

Actuator housings are typically made of either plastic or aluminium. Actuators with plastic housings are suitable for a wide range of mainly indoor applications. Aluminium housings help protect an actuator from harsh environments, such as fluctuating temperatures, chemicals, high forces, and vibrations.

An actuator with plastic housing is very suitable for use in a wide range of machinery. It should be noted that in case of frequent temperature fluctuations, plastic relaxation can occur, and the actuator's ingress protection can diminish over time. If used in harsh environments, an industrial actuator with an aluminium housing is recommendable.

An actuator with aluminium housing offers a high IP rating, and its form is unaffected by prolonged temperature fluctuations or chemicals, making it ideal for use in harsh environments.

There are many benefits of using an aluminium housing, and if the actuator is intended to operate under tough use conditions, then you should always take the housing design into consideration.

What are the main differences between plastic and steel gears?

There are pros and cons with any type of gear for actuators.

When comparing plastic gears to steel gears, plastic gears generally have lower efficiency and are more sensitive to high temperatures. However, if an actuator is used within its specifications, for instance, by running the actuator to its end stop each time or by avoiding mechanical blocking, the gear material will not be affected and will not influence the actuator’s overall performance or service life negatively.

Plastic gears are low-noise, which make them suitable for environments and applications where a low noise level is important.

Industrial actuators can be used in harsh environments with heavy loads, many duty cycles, or high temperatures. In such cases, steel gearing, including spur and planetary gears, prove the necessary robustness and efficiency needed for optimal actuator performance. Steel gears are not limited by fixed duty cycle restrictions, as the generated heat from a moving actuator will rarely reach levels high enough to harm the gear material.

Still, most LINAK® industrial actuators have a set duty cycle of 20% to ensure that generated heat will not affect other actuator components.

What can you do to achieve optimal actuator performance?

To achieve optimal actuator performance, you need a stable power supply, the right cabling and the right input voltage:

A stable power supply: Should match the nominal voltage of the motor.

Cabling: The shorter and thicker the cables, the less resistance there is for the input current to reach the DC motor.

Input voltage: In case you choose to run a DC motor with over or undervoltage, it can overload the motor.

What gear types are commonly used for electric linear actuators?

There are many types of gears in electric linear actuators, but the two gear types, plastic and steel gears, are commonly used for industrial actuators. Both types of gears come in different forms:

  • Spur gear is characterised by having straight teeth. Spur gears have a high efficiency, even in environments with high temperatures. However, the high efficiency comes at a cost, since these gears generate more noise compared to other types.

  • Helical gear is a good choice, when you want a smooth and silent operation. However, these gears offer a lower efficiency compared to the spur gears, and the axial thrust of the gear shafts generate heat, which must be considered in the overall actuator design.

  • Worm gear makes it possible to reduce the noise by increasing the gear ratio before running the actuator. Increasing the gear ratio equals using a gear wheel with a larger diameter. Worm gears of plastic often have a low efficiency, since this type of gearing is self-locking. If you need to further increase the self-locking ability, it will in some cases be necessary to add a brake.

  • Planetary gear is made from smaller gears circling a larger gear wheel. Typically, this type of gearing is very robust and efficient due to the equal distribution of force through the gear wheels. It provides a high gear ratio in a compact size and is used in several industrial actuators.

What is a DC motor?

A DC motor is a rotary machine that converts electric energy into mechanical energy.

Inside the stator, or the motor housing, the permanent magnets are mounted. These magnets create a constant magnetic field.

The armature consists of an electromagnetic coil connected to a DC power source, and running all through the motor is the shaft. The components all rotate inside the motor.

The two brushes touch the commutator that leads the DC power from the source to the electromagnetic coil.

Ball bearings ensure minimal friction between the shaft and the outer elements of the motor.

What is a spindle pitch?

The spindle pitch is the distance that a nut travels when rotating 360 degrees on a spindle. So, if the spindle pitch is 12 mm, it means that the nut travels 12 mm on one spindle revolution.

The higher the spindle pitch, the more efficient the actuator becomes since there is less friction between the nut and the spindle.

But a high spindle pitch also entails a low self-locking ability. With the self-locking ability, the actuator does not back drive when stopped at its target position, not even if is it exposed to high load or vibrations; unless, of course, it is supposed to move.

Generally, if you have a spindle with a low efficiency, the actuator is self-locking.

If the actuator is not self-locking, a brake is used to keep the actuator in a fixed position.

What is DC motor efficiency?

The efficiency of a DC motor is the ratio between the input power and the output power measured in Watt. And the power input is proportional to the load that must be moved. Many of the motor parts have a negative impact on the motor’s efficiency resulting in heat being generated. This is also true for very high or low ambient temperatures that are often present in the working environments of industrial actuators.

What is the stroke length?

The stroke length of an actuator refers to the maximum distance the actuator will move or extend. This is the range of linear motion from its fully retracted position to its fully extended position. In essence, it is a measure of how far the actuator's rod or piston can travel in a single motion.

The stroke length of an actuator depends on the length of the spindle. LINAK® actuators are generally very versatile and stroke lengths up to 1.20 meters can be specified according to customer requests. But, when considering actuators with long stroke lengths, there are some limitations. When running long strokes in push, we reduce the maximum load specification. The reason is that the higher the load and the further away from the inner position the nut travels on the spindle, the bigger the strain is on the actuator.

Can I copy the configuration from one actuator to another?

Yes, in Actuator Connect™ you can ‘Save configuration’. This is especially useful, if you are testing various features on a prototype and would like to make a backup of the configuration. Indeed a time-saving feature for e.g. parallel systems, as you do not have to configure every single feature on all actuators.

Can I customise an I/O™ actuator?

Yes! I/O actuators offer various wiring possibilities for input and output. The functionality of these inputs and outputs can be customised directly in Actuator Connect™, and the wiring diagram is updated accordingly.

A total of 6 wires can be customised. Some of the wires are reserved for a specific functionality and cannot be changed.

Do actuators with integrated controller have a built-in clutch?

No. For actuators with integrated controller the clutch is an unnecessary component. Instead, actuators with IC Integrated Controller™ use a current limit to ensure that the actuator automatically stops, if it meets an obstacle or other resistance in the application. Current limits are designed to help protect both the application and the actuator.

How can you use one of the outputs for real-time actuator monitoring?

Just like we offer real-time charts, you can get real-time information about the electric actuator’s current consumption or temperature via an analogue or digital signal directly to your PLC.

By using the analogue output, you can get a real-time view of the exact values – presented as either a 0-10 V or 4-20 mA signal (ranges can be customised).

With the digital signal, you can monitor a predefined range and be alerted if the measured values are outside of this range.

How do you ensure accurate actuator positioning?

One of the most important things to know about an actuator is its position. The physical position of a PCB controlled linear actuator is based on Hall effect sensors, counting the number of pulses per spindle revolution.

Traditionally, electrical switches were mounted at each end of the spindle which calibrated the positioning system every time a physical end stop was reached. To ensure reliable position feedback from the actuator, it was required to have at least one of these end-stop switches activated on a regular basis. If not, the position feedback could drift over time due to Hall pulses on the encoder being missed, predominantly while powered down.

Because of this limitation, an application where the actuator did not make use of the full stroke could result in inaccurate position feedback over time.

A new initialisation principle, developed by LINAK®, has changed the way linear motion can be initialised. It takes advantage of a small magnet mounted in the spindle nut, which moves past two Hall sensors on the actuator PCB located early in the stroke length at what we call the “zero” point. The sensors react when the magnet in the spindle nut passes by – thereby creating two Hall signals. The microprocessor checks for the intersection of the two magnetic fields and uses the intersection as a reference point for initialisation.

How do you get the data for calculating the B10 Life values?

The B10 Life values depend on many factors like temperature, vibration, load etc. that can all affect the lifetime of the actuator. At LINAK®, the current B10 Life values are solely based on the load.

To determine the B10 Life of an actuator, we test a number of actuators – with the exact same specification and in identical scenarios – and let the test run until all the actuators fail. Upon completion of the test, the B10 Life curves can be generated based on the results.

You can get more details in the video below.

How do you test for salt and chemicals resistance?

Machinery working in highly corrosive environments, such as agriculture and marine industries, require reliable movement solutions that are resistant towards a wide range of chemicals, fertilisers, and salt. To confirm effective and long-term reliability throughout their service life, LINAK® industrial actuators undergo a series of harsh corrosion tests.

The actuators are exposed to salt vapours, chemical substances, diesel oil, hydraulic fluid, and more. All these substances affect both the plastic and metal part of the actuators.

Watch how we test for salt and chemicals resistance.

How does a brushless DC motor work?

A brushless DC motor, also known as a BLDC motor, is driven by direct current (or DC electricity) and uses an electronically controlled commutations system.

Like all motors, a brushless motor has a stator and a rotor as its major parts. The rotor is made of permanent magnets, and the outer part – the stator – has several copper windings depending on the number of magnetic poles on the rotor. These windings are placed in slots which are axially cut along the inner periphery of the stator.

The motor is running when the rotor is spinning inside of the stator. Electronics make the rotor spin by inducing a series of magnetic fields in the copper windings that can push and pull the permanent magnets in a sequence that ensures a continuous rotation.

How does a clutch work?

The clutch disengages when the torque exceeds a pre-set limit. This happens, if the torque from the motor gets too high when running the actuator; the spring plate cannot hold the load and the ball bearings will be pushed out of their notches.

The clutch disengages, as the plates turn without creating movement, which means that the clutch disengages.

When the torque is lowered, the ball bearings will fall into place, and the torque will transfer into a linear movement again.

And in that way it protects the actuator and application in case of overload.

How does an electric I/O™ actuator ensure accurate position feedback?

The actuator must be initialised on a regular basis to ensure accurate position feedback. This is typically achieved by a physical endstop switch in both directions, but the accuracy can be reduced over time due to mechanical wear of the switches.

The I/O actuator, however, uses a new initialisation principle called ‘zero point’. With zero point, the position is initialised every time the piston passes a zone from 35-70 mm on the stroke without having to run the actuator to the physical endstops.

By substituting the electromechanical switches with a Hall-based system, the I/O actuator is better geared for operation in challenging industrial environments.

How does LINAK test cables?

LINAK industrial actuators are always tested with the cable mounted before leaving the production. This ensures that the actuator connection is correct and working.

For an actuator to comply with the IP69K rating (Ingress Protection), there must always be an overmolding at the end of the cable.

To retain the high IP rating, it is important to take precautions and design the wire connection to the machinery in a way, where the cable end is kept inside a closed, protected area. This will prevent water spraying from entering the connector and further into the actuator.

On LINAK industrial actuators, the cabling and housing are designed, so the cable can be replaced without affecting the IP rating.

How does the current cut-off feature work?

The current limiting algorithm describes the way the electric actuator responds to an obstruction. Or in other words, how it detects an obstruction and how fast it responds to it.

If the actuator’s current consumption rises above the set limit, the actuator regulates and tries to keep it below the set current limit by means of Pulse Width Modulation (PWM), which is used to regulate the motor speed. The actuator does this continually until the actuator stops moving (mechanically blocked) – determined by monitoring the Hall feedback signal. If there are no Hall pulses during a set time frame, the actuator stops.

How does the LED status indicator work?

Electric linear I/O™ actuators come with a transparent connector with integrated LED for fast diagnostics by simple visual inspection. This can be enabled as a software feature in the ‘Diagnostics’ option menu in Actuator Connect™.

The LED can show different colours depending on the actuator state and can be used to quickly determine whether the actuator is running as intended or shows a failure that needs to be looked at more closely.

When the actuator is fully operational, the LED will be green. If the colour of the LED changes (to either red or yellow), it indicates a system malfunction.

If the LED does not light up, try checking the power cable and power supply for improper connections or damage. In addition to creating a visual indication of the current status, it can also be used to see which actuator you are paired to via Bluetooth® on your PC (blue light).

The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG Inc. and any use of such marks and logos by LINAK® is under license.

How many electric linear I/O™ actuators can you run in parallel?

You can run up to 8 actuators simultaneously, thereby enabling smooth synchronised movement. Parallel is ideal if you want to distribute a heavy load across multiple actuators or to avoid mechanical stress caused by bending on, for example, a hood lift. It is a prerequisite that the actuators have the same characteristics - both in terms of mechanics and configuration across all features.

How to connect my I/O™ actuator to the Actuator Connect™ configurator?

This type of actuator can be wirelessly connected to a PC via Bluetooth®, or you can connect with a USB cable kit (sold separately). Whether you are going for the wireless or cabled connection, the first step is to apply either 24 V or 48 V power to the actuator (see the product label for further information).

Connect the signal cable to the actuator to ensure a stable Bluetooth connection. By default, the I/O actuator will be listed on the device list with its unique serial number (W/O#) and a Bluetooth symbol.

The USB cable kit includes two cables: a y-cable to be connected to both cable inputs of the actuator (power and signal), and a USB cable with an ethernet adapter that must be connected to the y-cable. If the same actuator is connected via the USB cable kit, it will also be shown with a USB symbol – note that in this case the name is linked to the USB cable and not the actuator itself.

Wait a few seconds for Actuator Connect to connect to the actuator and be ready for configuration.

Is it possible to get error codes directly to a PLC?

For applications where downtime is not an option, LINAK offers error codes as a digital output for easy troubleshooting.

During a 10 second time frame, you can read out error codes on the digital output. The actuator will send a number of pulses to your controller (PLC) depending on the error type – following the patterns in the table shown in the below video or on this troubleshooting page.

Error codes take up one of the digital outputs, which means that you can still use the other output for position feedback or endstop signals.

Is it possible to transform a single I/O™ actuator into parallel?

Yes. All electric I/O actuators are prepared for parallel with the violet wire – which means that you can set up your actuator for parallel movement even if it was originally programmed as a single actuator. This way, you can easily stock several I/O full actuators and configure them for parallel movement later.

The ‘Parallel’ option is displayed on the left sidebar on the Actuator Connect™ screen. When selected, you can configure and change the number of linear actuators in the parallel system.

Is it possible to upgrade my I/O™ actuator to a full version?

Yes! LINAK® is aware that not every project requires the full range of I/O options.

Therefore, you might experience that some features are locked in Actuator Connect™, if the actuator is a Basic or Customised version.

All the features can still be explored, but configurations and changes cannot be applied.

When you want full access to the entire range of possibilities, simply request an unlock key from your local LINAK office. Provide them with the actuator W/O# number (found on product label or in Actuator Connect), and request a key*.

Once this key is received, it is easy to make the upgrade in Actuator Connect.

*Please note that there is a one-time fee for each actuator upgrade.

My actuator is powered, but it does not appear in Actuator Connect™?

The Bluetooth® Low Energy antenna is mounted on the PCB inside the actuator aluminium housing. The housing reduces the signal strength significantly, and it is therefore important to also insert the signal cable. The signal cable has a dedicated wire to boost the Bluetooth Low Energy signal, and if the cable is not inserted, the actuator will have problems establishing a connection. Make sure you also insert the signal cable to make the actuator appear on the device list in Actuator Connect.

What are the advantages of speed ramp-up/-down?

LINAK® offers start settings (ramp-up) and stop settings (ramp-down) of the electric actuator as an alternative to an instant stop. With ramp-up and ramp-down, the actuator slowly accelerates to full speed when starting movement or slowly decelerates from full speed when stopping. With this feature you avoid bouncing and achieve smooth operation.

You can choose to go with the LINAK default settings or your own ramp speed setting. This feature provides smoother movement and reduces strain on the application, significantly extending the actuator service life.

What are the different cable types for electric linear actuators?

Generally, for LINAK® industrial actuators there are three cable types available: separate power and signal cables, a single cable for both power and signal, and a Y-cable.

Having separate power and signal cables increases flexibility and makes it easier to integrate actuators in various machinery. For example, you can have a power supply in one end and a motor control in the other end. For actuators with lower current consumption, a single cable can handle both power and signal. In other cases, an actuator may have a Y-cable, which is connected to the two connectors in the actuator, and a single plug for both power and signal in the other end.

What are the different types of mechanical brakes for actuators?

  • The disc brake: The disc brake is normally stacked directly on the spindle, where the discs squeeze together around the spindle to stop the movement. Being placed in direct contact with the spindle exposes the brake to both high force and heat. This type of brake is a wear part that is designed and tested to match the actuator life. The location of the brake directly on the spindle should also be considered in relation to the actuator’s build-in dimensions.

  • The single acting brake: The single acting brake contains an internal spring, which means that the brake works in one direction – either in push or pull. For an actuator with this type of brake it must be specified whether it needs to perform in push or in pull.

  • The dual acting brake: The dual acting brake is a very strong brake. This type of brake is integrated in the industrial LINAK® actuators, as their high-efficiency performance require a brake ensuring a high self-locking ability. Actuators with a dual acting brake can run in both directions without activating the brake as long as the movement originates from the electric motor. If the movement originates from the spindle, and in either direction, the brake will activate and keep the actuator in position.

What are the most common types of analogue feedback?

Analogue signals are a common type of feedback signal for PLCs and other control systems in industrial applications. One of the most frequently used is a 0-10 V signal where this voltage range represents the physical stroke length of the actuator.

Keep in mind that this type of analogue feedback is susceptible to noise and voltage drops over long cable lengths, which in turn could lead to inaccurate position feedback. Another common analogue signal is current – often 4-20 mA – which is less susceptible to noise and of course also voltage drops.

For both current and voltage, the feedback range can be scaled specifically to your needs, which can make it easier to integrate into your controls.

What does critical parallel mean?

Parallel works as a ‘critical’ system, which indicates that all actuators must be present in the system before it allows movement. The parallel system is controlled by a master which is the actuator with the highest serial number. The master commands the followers to move and receives status messages to ensure that the system is allowed to run only if everything is functioning properly. If it detects a malfunction or one of the following actuators struggles to keep up, the master will slow down so that the whole system follows the slowest in the system. For instance, if the load is not evenly distributed in the application.

What features are available on the digital outputs?

The actuator offers several digital position output options which can be configured exactly to your requirements. To offer full flexibility, the yellow and green wires can be used for the following outputs:

Digital position feedback as either single Hall or dual Hall. Single Hall does not take direction into account, and this logic must be programmed in the PLC. Dual Hall has two channels – A and B. Both have their own dedicated wire which makes it possible to determine the direction in which the actuator is running.

As either a supplement to the analogue position feedback or a stand-alone feature, you can choose endstop signals that give a signal when the actuator is fully retracted or extended. The same signal will also be applied if virtual limits are set in either direction – indicating that the actuator has reached its new endstop.

It is also possible to receive digital signals from the actuator while running – something that can, for instance, be used to turn on an LED to indicate that something is moving in the application.

In some cases, it might be beneficial to know when the actuator reaches a predefined endstop zone. This feature makes it possible to define a zone where the actuator can send a digital signal when it is inside that zone or at a current limit in that zone. In this way, you are no longer forced to design your application so that the physical endstop must be reached before receiving a PLC (Programmable Logic Controller) signal.

For most of these digital signals, you can choose between an active high or active low signal for easier integration in the application.

If you are looking for a way to power LED or a hand control, you can also choose a constantly high signal. The actuator will supply up to 100 mA to low-power devices directly.

What is a plug and play solution?

A plug and play solution is an easy-to-use option for quick and hassle-free actuator integration, which you can achieve by choosing a customised cable along with your industrial linear actuator. In most cases, all you need is an actuator with the preferred cable option and two bolts (one for the back fixture and one for the piston rod eye) – and your application will be up and running in no time.

What is a run condition?

In some cases, there may be external factors that need to be in place before the actuator can run. You can use a third digital input as an external precondition to allow movement.

A signal from for instance an external sensor can be connected directly to the actuator to verify whether these conditions are established before it runs.

What is B10 Life?

B10 Life is a metric used for estimating time to failure. The metric specifies a statistic value for the service life.

Put in other words, for actuators the B10 Life will show the point in time when 10% of the products are in the risk of failing. At the same time, the B10 value also shows, when there is a 90% probability of the actuator to meet the expected B10 Life, when used in accordance with product specifications. Also, the actuators must be configured identically.

There is still a 10% risk that a component can fail before reaching its B10 Life, and therefore, the B10 Life should not be considered a guarantee.

What is included in a report from the Actuator Connect™ configurator?

You can download a complete report as a PDF directly from Actuator Connect with general information about the actuator – type, position, last known status etc. – and comprehensive usage data that summarises all stored historical data – incl. error logs – over the entire lifespan of the actuator. You can use this data to analyse the performance of one electric actuator or compare several actuators.

The PDF also contains the actual wiring diagram and software configuration which can be used if you want to order new actuators or simply as a starting point for a technical discussion with your local LINAK contact.

What is self-locking ability in electric actuators?

Self-locking ability is one of the key selling points for electric actuators, as it prevents the actuator from back driving. In LINAK® actuators, self-locking ability is defined by the actuator being able to run with a full load and duty cycle; and when stopped, it will move a maximum of one spindle revolution before the actuator is locked in full stop.

There are several factors that influences the self-locking ability of an actuator. Spindle type and spindle nut, gear box and brake design, and DC motor control are just some of the main design considerations that affects the actuator’s ability to withstand loads when stopped.

What is the basic functionality of an H-bridge?

Controlling an actuator is based on an integrated controller or H-bridge, that changes the polarity of the voltage to the DC motor. Here you can benefit from low-current switching, since a high digital signal of only a few mA will cause the actuator to run.

The integrated H-bridge opens a variety of control options from the PCB such as speed and ramping.

This is the H-bridge, and in the middle is the power connection to the motor's positive and negative terminals. Four switches, in this case transistors, are connected to the power supply at the top and in the bottom of the H-bridge. These transistors replace the functionality of mechanical relays. The H-bridge controls the in and out movements of an actuator in a fairly simple way. When power is on two of the transistors must be activated to make the current flow diagonally – past the motor connection – making the motor run in one direction. To change directions, the current flow must be changed by deactivating the previously activated two transistors and activating the other two.

Illustration of an H-bridge with switch 1 and 4 closed

If you close switch 1 and 4, you have positive connected to the left side of the motor and negative to the other side, and the motor will start spinning in one direction.

 

Illustration of an H-bridge with switch 2 and 3 closed

If you instead close switch 2 and 3, you have positive connected to the right side and negative to the left side, and the motor spins in the opposite direction.

 

What is the difference between analogue and digital signals?

Information about the actuator position can be output as either an analogue or digital signal. Both options are offered to ensure compatibility with various PLCs and preferences.

If you compare the two signal types, there are various pros and cons to consider. As an example, the analogue signal is more prone to noise compared to a digital signal – but under the right conditions, it can also be highly accurate.

The digital signal can be used for more than just the piston position, as it can also be used for endstop signals, constant signal during operation and many other features.

What is the efficiency of a brushless motor?

The efficiency of a brushless motor is the relationship between power input and power output measured in watts.

The brushless motor is a highly efficient motor type with potential low energy loss from input to output.

The Hall effect sensors always know the position of the rotor, and therefore they can be used to regulate speed.

In the context of actuators, this means that you can obtain a constant speed even when increasing the load on the motor.

What is the function of a clutch in an electric linear actuator?

The clutch has two purposes:

  1. It protects the industrial machinery and the actuator.
  2. The actuator can be used without control electronics.

The clutch makes industrial electric linear actuators from LINAK® versatile and easy to implement in different machinery. In the actuator, the clutch can handle a push/pull of approximately 1.5 to 2.0 times its rated load at nominal speed before the clutch disengages.

The clutch disengages the rotational movement from the motor to the spindle and the gear. It is important to emphasise, that this is not a safety feature for when a heavy load is applied, while the actuator is powered off. The clutch disengagement mechanism is only applied, when the motor is rotating (powered on).

What is the main benefit of a brushless DC motor?

BLDC motors have a longer service life. Unlike a motor with brushes, the brushless motor does not have constant physical contact between the brushes and the commutator. As there is no friction wearing down the brushes, the brushless motor has a significantly longer service life than a motor with brushes.

What is the purpose of using a brake in an actuator?

The purpose of using a brake in an actuator is to ensure the actuator stays in its set position, when the power is turned off. There are three ways of ensuring a brake functionality in an actuator. Either the actuator is self-locking, which means that it does not need a brake to keep its position when power is off. Or it is necessary to integrate a mechanical or an electrical brake in the actuator. LINAK® actuators are either self-locking or feature different versions of mechanical brakes.

What kind of errors can be detected by the electric linear I/O™ actuator?

LINAK distinguishes between internal and external errors. If the actuator has detected an internal error and has stopped - try to repower the system or initialise the actuator. If the internal error cannot be solved, please contact your local LINAK office for further assistance. For external errors, you can find different remedies to solve a potential issue here.

What kind of real-time data can you get from an electric I/O™ actuator?

If you open the Actuator Connect™ configurator and the monitor option, ‘Real-time Charts’ is the first tab that appears. There are five things you can monitor in real-time on the graph:

  • Position in mm
  • Temperature in °C
  • Voltage
  • Current
  • Speed in mm/s

By conducting actuator test runs, it is possible to get an indication of how well the electric actuator can handle the real-world conditions it has been designed for.

For example: Do you have enough power? Or is the power consumption constantly maxed out? Or even noticing a current spike at a particular movement that you did not expect? The real-time data can help you review the mechanical design of the application and drive continuous improvements.

Which PCB features help protect the machinery?

A number of PCB features help protect the machinery running with a LINAK® industrial actuator. A pulse signal ensures the electronics are working properly, and the soft start/stop feature reduces the mechanical stress on the machinery and the actuator. This function is controlled by ramping up a PWM Motor Control signal and works in the same way as gradually releasing the clutch in a car.

Measuring current and temperature protects the PCB’s electronics and helps ensure reliable actuator performance. A microcontroller measures the current flowing through the H-bridge, and it shuts off the power if the current exceeds a predefined level. Sensors monitor both the H-bridge temperature and the ambient temperature inside the actuator housing and stop operation before the heat reaches damaging levels.

For EMC protection, the actuator PCB has a load dump functionality and a polarity protection. The load dump level for LINAK industrial actuators is predefined to 45 volts. If a voltage peak passes this level, the PCB will be shut off. Polarity protection ensures that the actuator is not damaged in case the power supply is wrongly connected.

Why add a safety nut in an actuator?

It is possible to add a safety nut in an actuator, for machinery where safety is a high priority. If, for example, the thread inside the nut on the spindle wears off due to wear and tear, the nut will immediately carry the full load and the actuator travels inwards. In this case, the actuator can no longer run outwards, and it must be replaced.

Why do you perform climatic testing for Ingress Protection?

Machinery operating in humid, wet or dusty environments must perform reliably in spite of environmental challenges. Ingress protection tests are therefore a crucial part of the testing programme for LINAK® industrial actuators. This is how we make sure our electric actuators are robust and operate reliably, even when exposed to high-pressure cleaning and dusty environments.

Watch how we conduct Ingress Protection testing.

Why do you perform temperature and humidity testing?

Our testing in environments with fluctuating temperatures and humidity ensures reliable performance of the actuators under harsh conditions. Also, special test patterns, such as dunk tests, are used to cover very demanding applications in the test plan.

Why do you test for electromagnetic compatibility (EMC)?

LINAK® industrial actuators are tested for electromagnetic compatibility (EMC) in accordance with a wide range of industrial standards. This is done to ensure actuator immunity to electromagnetic interference, and to certify that radiated emissions from the actuator do not affect the industrial machinery.

Why do you test for mechanical durability?

It is important, that the actuators can perform reliably throughout their service life. All LINAK® electric actuators, regardless of size and model, are subjected to durability tests.

Industrial applications are very different in terms of functionality, and LINAK actuators must support the required variations in movement patterns and performances in these applications, whether it is steady lifting of heavy loads or frequent operation. And the actuators must be able to do this throughout their maintenance-free service life. This is why LINAK industrial actuators are thoroughly tested for mechanical durability.

Watch how we test for mechanical durability.

Why do you test for vibration and shock resistance?

Actuators must perform reliably in dynamic and challenging environments. In our test centre, we subject the actuators to both vibrations, shock/bump and drop tests.

In off-highway vehicles and outdoor machinery like agriculture and construction, repetitive shocks, vibrations, and bumps are an obvious part of the machinery’s everyday life.

To deliver solid performance for many years, LINAK® industrial actuators are designed to absorb vibrations and tested rigorously to make sure they can withstand the stress of the rough terrain.

Watch how we test for vibration and shock resistance.

I have powered the actuator, but it does not show up on the device list in Actuator Connect™?

The Bluetooth® Low Energy antenna is mounted on the PCB inside the aluminium housing of the actuator. The housing reduces the signal strength significantly and it is therefore important to also plug in the signal cable. The signal cable has a dedicated wire to boost the Bluetooth signal and if this is not plugged in you will have trouble connecting to the actuator in Actuator Connect.

CAN bus - How to see which CAN bus version you are running

At LINAK®, we currently supply actuators with two different CAN bus software versions - v1.x or v3.x.

Determine the actuator version with the LINAK BusLink software
Connect the actuator to the BusLink software to verify the correct software version. When the actuator is connected you can find the ‘Connection Information’ tab. In the example below, the LA36 CAN bus actuator has version 3.0.

For further information, please see the BusLink service interface chapter in the CAN bus user manual.

BusLink version 3.0
 
 

What is the difference between version 1.x and version 3.x?
On CAN bus v3.0, we have introduced several new functionalities - such as hardware addressing, dynamic speed adjustment, soft start/stop commands and increased compatibility (125 kbps, 250 kbps, 500 kbps and Autobaud).
Please note that the soft start/stop now needs to be defined in the CAN bus command (in version 3.x). If left at 0, it will result in no ramping. If set to 251 it will use the actuator’s predefined factory settings. Any number in between will set the ramping time.

For further information, please see the Communication chapter in the CAN bus user manual.

How to clean your desk panel

Watch and learn how to easily clean your LINAK desk panel/switch in this short instruction video: How to clean it; which cleaning agents to use; and, last but not least, what you need to pay attention to.

Clean your desk panel with a soft damp cloth. Universal cleaning detergents may be used.

To disinfect the desk panel, use a 70% isopropyl alcohol either as a wipe or add a small amount to a soft cloth.

Warnings
The desk panel is not a sealed unit and there are electronics inside it. If liquids or moisture get into an opening, the PCB may be damaged, and the desk panel ruined.

So:

  • Avoid moisture penetrating any openings as this may damage the PCB inside the desk panel
  • Avoid spraying the cleaning agent or disinfectant directly on the desk panel as moisture may penetrate openings, damaging the PCB inside the desk panel
  • Cleaning agents and disinfectants must not be highly alkaline or acidic (pH value must be 6 to 8), and they must not contain bleach or chlorine
  • Do not use hand sanitiser gel as a cleaning agent

Alkaline and acidic cleaning agents may, over time, decompose the housing. Hand sanitiser gel may deposit on the desk panel buttons. Over time, the buttons may get stuck, or they may not work properly.

How do I control a dual actuator?

Dual actuators from LINAK only use wireless control options. The integrated Bluetooth® communication allows you to pair the electric actuator system with either one of our wireless hand controls, the LINAK Bed Control App or your own customised app.

How do I design a bed to fit a dual actuator?

Beds can be designed in many ways, but for adjustable beds the choice is typically between single actuator systems, dual actuator systems or a combination of both. However, the bed frames for each of these systems are very different.

For electric dual actuator systems the bed frame simply needs to have the standard spacing between the crossbars responsible for adjusting the back or leg part of a bed. This crossbar must also have twist brackets mounted so the dual actuators have something to push to make movement.

In this video you can see how mounting happens.

How do the electric lifting columns for sit stand tables and office desks work?

LINAK lifting columns are electric columns that offer height adjustment of various kinds of furniture and other applications. In order to adjust the columns you will always need a full system which consist of lifting columns, the CBD6S control box and a control panel/desk panel to control the movement.

Furthermore, you need to connect the system to power.

Office desks system with motor housing lifting columns

How does a dual actuator work in an adjustable bed?

A dual linear actuator is mounted on crossbars with twist brackets on. This means that the rotational movement created by a dual actuator pushes the twist bracket in a way that rotates the cross bar which then in turn moves some part of an adjustable bed.

IC parallel actuator system - How to add, remove, or replace an actuator

How to add, remove or replace an actuator in your IC™ parallel actuator system.

To add or remove an actuator:

  1. Connect all actuators to BusLink to configure the number of actuators in your parallel system
  2. Before running the system, let the system initialise itself

To replace an actuator:

  1. Power the system off and replace the actuator
  2. Power the system on and the new actuator will automatically catch up to the position of the remaining actuators

For more information about initialising your parallel IC system, please visit How to initialise your IC™ parallel actuator system.

This FAQ is relevant for the first generation of our IC Integrated Controller™: Basic, Advanced and Parallel.

IC parallel actuator system - How to initialise the system

How to initialise your IC™ parallel actuator system.

Initialise the system in two ways:

  1. Let the system initialise itself via Recovery mode, where the actuators automatically run in steps of 2000ms on and off for a full stroke length
  2. Initialise the system manually by using the BusLink software. Only the actuator in ‘position lost’ needs to be initialised by running the actuator to its mechanical end-stop in one direction

For information about troubleshooting on your parallel IC system, please visit How to troubleshoot on your IC™ parallel actuator system.

This FAQ is relevant for the first generation of our IC Integrated Controller™: Basic, Advanced and Parallel.

IC parallel actuator system - How to troubleshoot on the system

How to troubleshoot on your IC™ parallel actuator system.

If an actuator has lost its position, the parallel system will enter Recovery mode and initialise itself. If the system is unable to run in recovery mode, please continue this troubleshooting process:

  1. Check cabling, power supply and communication signals between actuators
  2. Connect each actuator to the BusLink software and look at the error codes to identify which actuator has caused the system to stop

If it is an overcurrent error code, restart the system by running it in the opposite direction.

If these error codes are registered, actuator replacement is necessary: H-bridge fault, switch mode power supply fault, or hall sensor failure.

LINAK Spyder™ is a cost-efficient actuator system for 3-4 motor bed applications powered by an external SMPS.


Relevant for the following products:

What is the IP degree of the LINAK Spyder™?

The LINAK Spyder is rated IPX4 when the handset is connected to the CA10 control box. IPX4 means that the products are protected from splashing and suited for manual cleaning, ideally with a damp cloth.

Ensure that the power cable connector is kept dry during cleaning.

The CA10 platform, powered via an external power supply (SMPS10), is certified in accordance with the general standard for medical electrical equipment, IEC 60601-1.

The same applies to the SMPS10 power unit. The CA10 is designed for IPX4 according to the requirements of the standard for medical beds, IEC 60601-2-52, and the SMPS10 is designed for IP21 according to the requirements of the standard IEC 60601-1-11 for medical electrical systems used in the home healthcare environment.

The IEC 60601-1 states that the requirements of an ME system distinguish between ‘within’ and ‘outside’ the PATIENT ENVIRONMENT. When in active use, the SMPS10 is outside the PATIENT ENVIRONMENT and if/when cleaned, there is no longer a connection between the bed and the SMPS10.

What are the different types of dual actuators for adjustable beds?

At LINAK we work with two types of dual actuators: Standard and Advanced.

The Standard versions offer back and leg adjustment with only one unit as well as the following integrated features: mechanical emergency lowering, low stand by power consumption and integrated under bed light.

The Advanced versions of the LINAK dual actuator offer the same features as the Standard version – and then something extra. In addition, they offer the option of parallel drive of two beds, the possibility of saving favourite positions and adding extra accessories such as massage motors or extra under bed light.

You can tell the Standard and Advanced versions apart by looking at the plugs. If there is an available plug after having connected the power cord – you have an advanced version.

What are the different types of lifting columns for office desks?

LINAK offers two choices for lifting columns for sit-stand tables or height adjustable desks where you need to add the desk legs. We offer lifting column systems where the columns either come with a motor housing or they are what we call in-line columns.

What is anti-collision in office desks?

The anti-collision feature in various sit stand desks is basically a feature that prevents your desk from continuing to run if it were to run into something. Instead it will stop and run a little backwards. This is how it will minimise the damage.

If you want to know more about our different types of anti-collision solutions please follow the links below:

Which version of the LINAK dual actuators is the best?

The question about which dual actuator is best depends entirely on the bed you want to integrate movement into. Therefore, it is not possible to say which LINAK dual actuator is best for your bed design.

First, you will need to know how much force your bed design requires. For heavy constructions and mattresses, we recommend TD5, whereas for slatted beds with lighter mattresses, we recommend TD4.

Secondly, you will need to know which features you want your bed to have. For all the standard features the standard version of the dual actuator is fine. However, should you require an extra actuator, parallel drive of two beds, and also want to offer the possibility of saving favorite positions, you will need an advanced dual actuator.

To find out exactly which system fits your requirements, our sales people are always ready to help you find the right solution.

Below you will find a step-by-step guide on how to get spare parts and technical support from your equipment manufacturer.

In this guide, 'end user' refers to the person who uses the product, while 'manufacturer' refers to the company that produced the product, such as a desk or a bed.

Step 1: Contact the equipment manufacturer or retailer
LINAK® is a leading supplier of actuators and components to equipment manufacturers. As each of our customers' products is unique, LINAK cannot provide products or technical services directly to end users. For prompt service, spare parts, or repairs, we recommend contacting the original equipment manufacturer or the retailer from whom you purchased your product.

Go to our product pages for basic technical information.

If you encounter any issues with your electric height-adjustable desk, please check our troubleshooting guide for helpful tips and solutions.

Step 2: Who do I contact?
For end users:
Please visit the equipment manufacturer or retailer's website for support, or refer to your product’s user manual. Contact details are usually found on the manufacturer’s label on the product (not the silver LINAK label on the component).

For equipment manufacturers:
Please contact your local LINAK office.

Step 3: What do I need to know before I call?
For end users:
If your request concerns replacement, repair, or support of a LINAK component, please contact your equipment manufacturer and provide them with the complete item number (Item No.) from the silver LINAK label. This information will help them assist you more effectively.
