Manual Control
Turning the knob either way results in no movement
The knob may have been disabled.
Check that the knob.enable (T:107) setting is correct.
Restore the default parameters through the system restore (T:36) command.
The device won't cover the full range of travel.
The device hasn't been homed.
Turn the knob anti-clockwise until the device reaches the fully retracted position (closest to the
motor). The device will home and the full range of travel available.
Unexpected Behaviour
The device doesn't respond to a move command.
The device needs to be homed before use.
Send the home (T:1) command.
The device is moving on its own and running against the ends of travel.
The position encoder has de-synchronized.
Reset the device by power cycling it or sending the system reset (T:0) command, then re-initialize it
with the home (T:1) command.
The device is moving very slowly. It used to move faster.
The speed settings may have been changed inadvertently.
Send a system restore (T:36) command.
The device makes louder than normal noise during travel and is frequently slipping.
This condition happens if the thrust needed is more than the thrust available from the device.
Check the following:
The force on the device is less than the maximum thrust.
◊
The voltage matches the specified voltage. Read the voltage using the get system.voltage
command. Voltage less than the specified voltage for the device will reduce the device’s
maximum thrust.
◊
Test the following:
Try a slower target velocity. Stepper motors produce more thrust when moving slowly.
◊
Try a lower acceleration and deceleration.
◊
Clean the screw and lightly re-grease it with a grease that does not degrade plastics.
◊
The device has repeatability errors smaller than 4 full steps.
If steps aren't being skipped, friction or loose parts may still cause some variation when returning to a
position.
Please contact Zaber Technical Support.
The device doesn't cover the full range of travel, or runs into the end.
A setting might have been inadvertently changed.
home (T:1) the device to see if this corrects the behaviour.
◊
Send a system restore (T:36) command.

Communication Errors
There is no communication with the device, the Yellow LED does not come on or flash.
There are several things that should be checked:
