1.2 Safety Considerations
As with any electro-mechanical device, safety should be considered during the installation and operation of your GSM Series actuator. Throughout this manual you will see paragraphs marked with CAUTION and WARNING signs as shown below.
CAUTION WARNING
Pay particular attention to these paragraphs. They are intended to provide you with helpful information to ensure safe and trouble-free installation.
2.0 SYSTEM CONFIGURATION
2.1 GSM Series Actuator System Configuration
GSM Series actuators incorporate an integral brushless servo motor. The design of this motor and selection of the proper feedback configuration allows GSM Series actuators to be powered by nearly every brand of brushless motor amplifier on the market.
This flexibility allows GSM Series actuators to be incorporated into the highest performance single and multi- axis motion control systems in use today. In applications varying from food and beverage packaging to multiaxis turning centers to aircraft assembly, the GSM Series of actuators show incredible performance and durability.
The high torque to volume ratio available from a brushless motor, combined with the robust, high speed and high load capability of the planetary roller screw, make the Exlar line of linear actuators a true, all electric replacement for cumbersome high maintenance hydraulics. The use of electronic servo control provides simpler set up and more precise control than hydraulic systems as well.
The schematic, next page, shows the typical connections for a single axis system incorporating an Exlar GSM
Series actuator and servo amplifier. Each brand of brushless motor amplifiers may have unique wiring requirements, parameter settings and operational principals that affect how the actuator operates. The drawing on the following page shows general connection principals for typical resolver and encoder feedback amplifiers. Details on connections to specific brands of amplifiers can be obtained from www.exlar.com.
WARNING: Attempting to connect the power cable to the motor feedback connector may cause damage to the connector. Verify that pin patterns match before attempting to connect cables to actuator.
Never attempt to connect or disconnect the actuator with power applied. Dangerous voltages are present. Damage to equipment and injury to personnel can result. Many amplifiers have voltage present for a considerable time period after incoming power is removed. Take care to insure that the amplifier has discharged all power.

Typical System Connections
2.2 Typical System Wiring
Please refer to www.exlar.com for information on connectors and wiring.
2.3 Feedback Information
GSM Series actuators incorporate a quadrature incremental encoder with commutation signals as the primary rotary feedback device. The alignment of this feedback device is dictated by the amplifier that the end user chooses for operating the actuator. This amplifier is indicated in the model number of the
GSM Series actuator as a 3 digit code consisting of 2 letters and 1 number.
Each amplifier has specific requirements for the feedback on the motor. Not all encoder-based amplifiers can use the same encoder, encoder alignment or relative direction of encoder rotation.
Many amplifiers offer software that allows the entering of parameters or the downloading of motor data files that dictate how the feedback must be set up on the motor. Exlar can provide many of these data files or the proper parameters to enter. Entering motor parameter data to some amplifiers may require assistance from the amplifier manufacturer.

12/22/11
Exlar Corporation
952-500-6200
Feedback Alignment
When Exlar manufactures a GSM Series actuator, the proper feedback is selected, mounted, aligned and test run on the amplifier that the customer plans to use, or one that is known to be equivalent for confirming proper feedback alignment and operation. In any case where it is determined that the feedback has become misaligned, or an amplifier change is made requiring the feedback to be aligned differently, it is recommended that Exlar be contacted and arrangements made to have that procedure performed.
Feedback Wiring
The wiring of the feedback device is critical to the operation of the actuator with the selected amplifier.
Wiring the feedback cable improperly can cause unstable operation, incorrect operation or no operation at all. In some cases, if the proper current limits are not set in the amplifier, improper wiring of the feedback cable can lead to damage of the motor.
Encoders
An incremental encoder is an electronic rotary device that transmits a string of electrical pulses when rotated. Most brushless motors or servo systems that use incremental encoders use what is called a quadrature encoder. Typical brushless motor encoders use two data channels, labeled A&B, to provide direction, velocity and position information. The Channel labeled I or Z has one pulse per revolution and is called the index. The channels labeled as hall signals, or commutation signals, are typically labeled S1, S2 & S3; Hall 1, 2 & 3, or Hall A, B & C, depending on the manufacturer's conventions.
These signals give the amplifier the commutation information that it needs to properly rotate the motor.
GSM Series Feedback Devices
Standard GSM Series actuators use encoders as their primary feedback device. Depending on the amplifier that will be used to operate the actuator, the hookup of the actuator can vary. Always consult
Exlar for the correct wiring details or visit www.exlar.com.
2.4 Cable Routing
Over time, liquid contaminants such as oil and cleaning solutions will run down the cables and into any exposed connectors. To minimize the introduction of contaminants to the connector, route the cables so that there is a loop in the cable just prior to its attachment to the connector.
Two examples are shown below, depending on the orientation of the connectors. Units mounted in such a way that the connectors are on the bottom surface of the actuator require no looping.

2.5 GSM Series Linear Actuator Anti-rotation Option
The unique design of the GSM Series linear actuators allows the extending rod to rotate. This simplifies the setup of the actuator by allowing the user to rotate the rod and thread it in and out of the actuator for mechanical attachment or system testing.
This feature also requires that the rod be kept from rotating when used in its dedicated application to insure proper linear motion. In most applications, such as those where the load is coupled to linear bearings or some other support device, the load cannot rotate, providing anti-rotation for the extending rod of the actuator.
For applications in which the load is free to rotate, Exlar offers the anti-rotation systems shown below.
The drawings below show the rod and bushing on only one side of the actuator. For long stroke actuators, the rod and bushing are required on both sides of the actuator.

2.6 GSM Linear Actuator External Limit Switch
With the anti-rotate option (Section 2.6) the GSM actuator can accommodate 1, 2 or 3 external limit switches for use as end of travel limit switches or home position sensors in a low profile extruded channel housing. A bracket with inductive proximity switches mounts to the tie rods and senses a traveling magnet inside the extrusion.

2.7 Internal Holding Brake
Many applications require the addition of the rear internal holding brake. The brake is held open by the supply of power to a magnetic/mechanical clutch. Whenever there is not power to the brake, the armature is held in place to prevent the inverted roller screw from turning and prevent the output rod from back driving, which therefore prevents the output rod from moving.
The holding brake is permanent magnet engaged and electrically released. The mechanical advantage of the roller screw allows the holding brake to prevent back driving of the load. The holding capacity of the brake is sufficient to hold the rated force of the actuator when used in grease lubricated units.
Historically, Exlar actuators and motors with holding brakes provided a transient suppression diode wired internally to the actuator or motor. With the changes in servo amplifier and control technology, there are now instances where the diode is not required to be within the motor. An example of this is a control system using a dedicated brake control relay containing transient suppression components.
Because of this change in technology, Exlar now provides the transient suppression diode separately from the actuator, for inclusion in the brake control circuitry as needed by the end user. A schematic is provided below showing the typical use of the transient suppression diode.

Exlar Corporation
952-500-6200
If the user is uncertain about the requirements for transient suppression, they should refer to their servo amplifier or controller technical documentation, or contact their servo amplifier or controller manufacturer for technical support.
For connection of your amplifier and actuator (including rear brake leads), refer to the wiring information at www.exlar.com/TI_install_scheme.html.
The rear brake option adds length to the dimensions of the GSM actuators as follows: (See drawings in
Section 5.2.)
GSM20: Add 1.784 inches (45.3 mm) if ordering brake
GSM30: Add 1.6 inches (40.6mm) if ordering brake

DO NOT attempt to operate the actuator with the brake applied. Allowing the actuator to operate with the brake applied may cause serious damage to the actuator and/or the brake. Do not use the brake to support heavy loads while an operator is under the load. Provide another means to lock the load in position. The brake is a spring applied friction mechanism and does not provide a positive lock.

3.0 INSTALLATION AND OPERATION
3.1 Lubrication Requirements
The GSM Series actuator is shipped from the factory fully greased and ready for installation. Exlar recommends using Mobilith SHC 220, a high performance, extreme-pressure grease. The unique physical properties of the synthetic base oil provides outstanding protection against wear, rust, corrosion and high or low-temperature degradation. Mobilith SHC allows for very low starting and running torque values. Its operating range is -40 degrees C to 177 degrees C (-40 degrees F to 350 degrees F).
3.2 Mounting Configurations
The standard configurations available are Rear Clevis, Front Flange, Extended Tie Rods, Side
Trunnions and side tapped mounting holes. General drawings are shown in the product section guide.
3.3 Mounting Considerations
Every effort should be made to minimize misalignment. Any misalignment will decrease the life of the components within the actuator and also may create problems within the application associated with misalignment.
Excessive side load on the output rod of the actuator will dramatically reduce the life of the actuator and should be avoided completely. Side load can be caused from misalignment or loading that is not inline with the actuator output rod.
3.4 General Operation
The GSM Series linear actuators function in the same manner as a brushless servomotor. The servo amplifier is used to rotate the motor at controlled speed and torque, and for controlled numbers of revolutions and move times. This rotary motion is translated into linear motion by the internal planetary roller screw mechanism of the GSM Series linear actuator.
The relationships between the rotary motion of the motor and the linear motion of the actuator corresponds to the following relationships:
Linear Distance Traveled (in) = (Motor Revolutions)*(Roller Screw Lead)
Linear Speed (in/sec) = ((Motor RPM) / 60)*(Roller Screw Lead)
Linear Force (lbf) = ((Motor Torque (in-lbf))*(2
π)*(efficiency)) / (Roller Screw Lead (in))
All of the above relationships require proper anti-rotation of the GSM Series actuator rod.
For more information on sizing and selection of GSM Series actuators and servo amplifiers, consult the sizing and selection section of the Exlar catalog.

Motor RMS current must be maintained at a level below the continuous current rating of the GSM Series actuator or damage to the motor stator will result.
The peak current setting must be maintained at a level below the peak current rating of the GSM Series actuator or damage to the stator will result.
Care should be be taken not to exceed the physical travel limits of GSM Series Actuators.
Doing so will cause the actuator to end-crash internally. End crashes can physically damage the roller screw and the internal components of the actuator. Care should be taken to avoid high speed impact with objects of high rigidity that immediately stop the travel of the actuator with no deceleration or energy absorption. An example would be a high speed impact of two solid steel parts. The resulting impact will create a very short effective deceleration time. Kinetic energy contained in the rotating inertia of the actuator and motor can possibly generate extremely high impact forces that exceed the mechanical capacities of the actuator and cause physical damage to the actuator. For applications requiring this type of impact, contact Exlar application engineering to insure that the actuator is properly sized or provisions made to absorb the induced energy.
4.0 MAINTENANCE PROCEDURES
4.1 Disassembly
If your actuator has a preloaded roller screw, do not remove it from the cylinder.
Preloaded screws require special tooling and procedures for proper disassembly and reassembly. Contact Exlar Corporation to arrange for maintenance of a preloaded screw actuator.
Refer to the exploded view on the following page.
1.) Remove the actuator assembly from the machine by disconnecting the cables, main rod coupling and actuator mounting bolts or fasteners.
2.) If your unit does not have an external anti rotate assembly, skip this step. Loosen the two machine screws that clamp the anti-rotate cross member to the actuator output rod. Slide the anti-rotate mechanism forward and off the actuator.
3.) Remove the rear tie rod nuts from the back of the actuator.

12/22/11
Exlar Corporation
952-500-6200
The end cap houses the feedback device. Alignment of this feedback device to the phases of the motor is critical to the operation of the system. Extreme care should be taken when removing the tie rod nuts or tie rods so as not to twist or pull on the end cap of the actuator. Some feedback devices are sensitive to movement of their mounting surface once installed and can be damaged if care is not taken.
4.) If your actuator does not have a front flange, skip this step. Slide the front flange forward and off the actuator. The tie rods will remain attached to the front flange.
If your actuator has a preloaded roller screw, do not remove it from the cylinder.
Preloaded screws require special tooling and procedures for proper disassembly and reassembly. Contact Exlar Corporation to arrange for maintenance of a preloaded screw actuator.
5.) When the face plate is removed, the thrust bearing and the open end of the roller screw internally threaded cylinder (ITC) are visible. The roller screw can be removed by turning it counter clockwise and threading it out of the cylinder. It may be necessary to keep the roller screw cylinder from turning to remove the screw.
4.2 Lubrication Maintenance
Grease lubricated units will require periodic inspection and renewal of the bearing and roller screw grease. The table below shows the recommended grease renewal period.

Grease Renewal
The bearings located in the front of the actuator, the roller screw cylinder, and the roller screw assembly are the components that require grease. They require a coating of grease. They do not need to be packed with grease. Excess grease requires more torque from the motor when returned to operation, and does not improve the lubrication of the unit.
1.) Use a brush to work approximately 0.5 in
3
of grease for every 3 inches of stroke length into the roller screw cylinder. Be sure to cover all of the threaded areas of the cylinder.
2.) Use a brush to work grease in to the roller screw assembly. Be sure to cover all the threaded surfaces of the screw assembly. This can be accomplished by applying grease to a few places on the
GSM Manual.doc

roller screw assembly and rotating the components repeatedly in both directions to work the grease into the assembly.
3.) Force grease into the front of the thrust bearing assembly. Make a concerted effort to insure that the grease is well worked in. Grease must reach the bearing just behind the bearing that is visible as well. Use the following amounts of grease for each size roller screw and bearing:
GSM20: 0.5 in
3
GSM30: 0.75 in
3
GSM40: 1.00 in
3
4.3 Reassembly
1.) Rethread the roller screw into the internally threaded cylinder (ITC). It is a multiple start screw, and this is not always easy. DO NOT FORCE THE ROLLER SCREW INTO THE CYLINDER. It is best to have the actuator vertical with the open end of the roller screw cylinder facing up. Position the roller screw above the cylinder so that it is aligned axially with the ITC. Slowly turn the roller screw
1/4 to 1/2 a turn counterclockwise with it in contact with the ITC. This will help to align the threads on the roller screw with the threads in the ITC. Rotate the roller screw clockwise and it should begin to thread into the cylinder. If it does not turn freely, remove it and begin again. When threading the screw into the cylinder, it will roll freely into the actuator. When it reaches the portion of the cylinder that contains the motor magnets, the roller screw will be more difficult to turn because of the magnetic field of the magnets. THIS IS NORMAL. Continue to thread the roller screw into the cylinder. When it reaches the bottom, it will become difficult to turn and the motor and bearings will begin to rotate with it. The roller screw is now fully inserted into the cylinder.
2.) Place a small amount of seal lubricant on the inside surface of the seal/bushing assembly.
3.) Carefully slide the face plate and bushing/seal assembly over the actuator rod end, while guiding the tie rods through the holes in the rear end cap of the actuator. The seal is a tight fit on the rod end.
Take care not to damage the seal on the threads of the extending rod. Standard GSM Series rods have a chamfer to provide a lead in for replacement of the seal and bushing. Be sure that the faceplate seats completely and squarely on the front of the actuator. The inner surface of the faceplate provides the pre-loading for the bearings, and it is important that it is properly seated.
Units With a Front Flange
Replace the faceplate as described above. Remount front flange by sliding tie rods through the holes in the faceplate and through the holes in the rear end cap. Pilot the flange on the pilot diameter located on the front of the faceplate.
4.) Replace the rear tie rod washers and nuts and tighten to the proper torque. Tighten the nuts simultaneously by partially tightening each in an opposing corner pattern until each is torqued to the rated value shown below.
GSM20: 20 lbf-in (1.7 lbf-ft, 2.26 N-m)
GSM30: 90 lbf-in (7.5 lbf-ft, 10.16 N-m)
GSM40: 240 lbf-in (20 lbf-ft, 27.12 N-m)
5.) If your actuator has an external anti-rotate mechanism, slide the rod or rods of the anti-rotate mechanism through the front flange and into the guide bushing or bushings mounted to the rear of the flange. Position the extending rod so that the wrench flats are parallel to the long side of the flange.
Slide the cross member assembly of the anti-rotate mechanism over the end of the rod and onto the wrench flats. Tighten the two screws that clamp the assembly to the actuator rod.

4.4 Seal Maintenance
If you have chosen the IP65 sealing option (-P5) on your GSM actuator, it is recommended that the main rod seal and bushing assembly (FSB) be replaced at the suggested time of lubrication. The main rod seal can be removed by threading it out of the face plate using a standard rod seal gland wrench or spanner wrench. A new main rod seal can be slid over the main rod, taking care not to touch the seal material to the threaded rod end. To have this service performed for you, contact Exlar Engineering or arrange with Exlar Returns
Department to send your unit in for service.

Note: Some actuators are provided with special FSBs due to chemical exposure or other special requirements.
Contact Exlar if there is a question about your particular actuator having a standard material FSB.
FSB Installation/Replacement:
1. Using proper sized gland or spanner wrench, remove existing FSB from actuator face plate, and slide off the actuator rod. This will require the removal of any rod attachments. One source for gland wrenches is Martin Fluid Power, http://www.mfpseals.com/seal_repair_kits/parker-2.shtml

2. Remove the o-ring from the 0-ring groove located inside the opening from which the FSB was just removed.
3. Replace the o-ring with the o-ring supplied with the new FSB.
4. Taking care not to touch the seal material to any sharp rod features such as threads, slide the FSB on to the actuator rod and to the face plate.
5. Using the appropriate gland and spanner wrench, tighten the FSB to the proper torque level indicated in the previous table.

Definitions *Values are approximate and depend on motor voltage and commutation type. See motor specs for exact motor torque.
Force Rating: The linear force produced by the actuator at continuous motor torque.
Max Velocity: The linear velocity that the actuator will achieve at rated motor rpm.
Continuous Motor Torque: The torque produced by the motor at rated continuous current.
Maximum Static Load: The mechanical load limit of the actuator if re-circulated oil or other cooling method is used to allow higher than rated torque from the motor.
Armature Inertia: The rotary inertia of the armature of the GSM Series actuators. For calculation purposes, this value includes the screw inertia in a GS actuator Inertia tolerance is +/- 5%.
Dynamic Load Rating: A design constant used in calculating the estimated travel life of the roller screw. The dynamic mean load is the load at which the device
will perform one million revolutions.

7.0 TROUBLESHOOTING PROCEDURES
This section provides you with guidelines and hints on troubleshooting various problems that may be encountered during installation and operation of your Exlar GSM Series actuator
.
Symptom / Trouble Possible Cause / Troubleshooting Procedure
No response from actuator.
Actuator seems to be enabled
(receiving current) but is not operating or is operating erratically.
Actuator cannot move load.
1. Check amplifier for faults that may indicate problem.
2. Check to insure that amplifier is enabled.
3. Check for proper wiring.
1. Amplifier may be improperly tuned. Check all gain settings.
If a motor file or parameters specific to your amplifier/actuator combination have been supplied by Exlar, be sure that they are entered or downloaded properly.
2. Amplifier may be set up improperly for the particular motor being used. Check amplifier settings for number of poles, voltage, current, resistance, inductance, and inertia.
3. Feedback wiring may be incorrect.
4. Feedback conductors touching, or feedback cable may be damaged.
5. Motor phases are wired incorrectly or in incorrect order. (R,S,T)
6. Feedback (resolver or encoder) is improperly aligned. Contact
Exlar.
1. Load is too large for the capacity of the actuator or too much friction is present.
2. Excessive side load.
3. Misalignment of output rod to load.
4. Amplifier has too low of current capacity or is limited to too low of current capacity.
1. Check actuator mounting. Insure that the actuator is securely mounted.
2. Amplifier is improperly tuned (wrong gain settings). Tune amplifier.
1. Install Exlar anti-rotation assembly or incorporate anti-rotation into the application.
Actuator housing moves or vibrates when shaft is in motion.
Output rod rotates during motion and thus does not provide proper linear motion.
Limit switches not functioning. 1. Limit switches wired improperly. Refer to manual.
2. The device being driven by the limit switches is not compatible with the electrical output of the limit switch. Check device requirements.
3. Switches have been damaged by improper wiring or improper voltage applied. Replace switches.
Brake does not hold load in place.
1. Load is larger than the capacity of the brake.
-check load level against actuator rating.
-oil lubricated units reduce holding capacity of the brake.
2. Brake is not engaged. (Power is not removed from brake)
3. Brake is being used as other than a power loss holding brake.
Actuator is overheating. 1. Insufficient cooling for application requirements. See oil cooling section of this manual or Exlar catalog or contact Exlar engineering.
2. Actuator is being operated outside of continuous ratings.
3. Amplifier is poorly tuned causing excessive unnecessary current to be applied to motor. Check Gain settings.
