Troubleshooting Linear Thrusters
Description Possible Cause Corrective Action
Noises or vibrations Linear thruster mounting is not fastened
properly. Verify correct mounting and torques
Load or mounting accessory fixture is not
fastened properly.
Linear thruster not tuned Tune linear thruster
Bearing wear Replace bearings
Excess slider friction or rubbing Linear thruster is not mounted to a flat
rigid surface per mounting guidelines. Review mounting guidelines
Improper fastening of mounting feet
accessories. Review mounting instructions.
Metal debris or hardware on magnet
surface of slider. Remove debris.
Debris on strip cover Clean strip cover
Debris or loose hardware on slider
bearings Remove debris from using masking tape
Bearing wear Replace bearings
No response from linear thruster Controller or drive not enabled Enable controller and drive
Controller or drive faulted Reset the controller or drive
Improper or failed wiring Verify correct wiring
Linear thruster is enabled but operating
erratically or not at all. Motor Feedback Cable connection may
be faulty or intermittent Run Hookup Test, verify wiring
Encoder magnetic strip is damaged Verify function of linear encoder over full
range of travel. If a particular location is
malfunctioning, replace incremental
encoder magnetic scale.
If using an absolute encoder, return for
repair.
