There are five different error messages:
Wrong stage detected: No stage has been connected to the PDXC2 or there are problems with the stage.
Excessive current detected: An overcurrent condition has occurred in the device, and the output will disable.
Excessive temperature detected: The device's temperature has exceeded the acceptable range, and the output
will disable.
Abnormal stage move detected: An abnormal move has been detected for the stage. This error occurs if the stage
is driven to a set position, but manually pushed to a different position. Please note that, abnormal move detection
is only used for stages with encoders in closed loop mode and the button is enabled.
The table below shows the processing for the error messages above; if any of the errors repeatedly occur, contact
Thorlabs tech support.
Power down device and check the connection status. Check problems with
the stage.
Excessive Current

Ensure that the environmental temperature is within the required range and
that the device housing's ventilation is not blocked before power cycling the
PDXC2.
Excessive Temperature

Power off and restart the device.
Abnormal Stage Move

Check to see if there is excessive load on the stage or if something is
mechanically interfering with the stage’s motion. If there are no issues
found, the user can ignore this error and the error information will be
cleared after the user sets a new target position or starts a home operation.
