How to fix THORLABS GVS012 Scanner motor not responding?
If the THORLABS Scanner motor isn't responding, ensure power is correctly applied to the board. Also, check for faulty or improperly connected cables. Try resetting the device to clear any faults. Finally, verify the device is not disabled by checking the jumper settings.
Why is my THORLABS GVS012 unstable?
Scanner instability can occur if the driver board is incorrectly tuned to the motor, so re-tune it. Ensure the driver board is connected to the correct motor. Check and reset any tampered potentiometers. Avoid driving the motor with excessive amplitude and frequency.
What to do if THORLABS GVS012 galvo periodically becomes unstable?
If the THORLABS Scanner galvo periodically becomes unstable, it may be due to an incorrectly tuned galvo driver card. In this case, re-tune the galvo driver card. Also, ensure the error signal remains within acceptable limits, as exceeding the maximum error signal value can cause instability.
Why does THORLABS Scanner position signal overshoot and grow over time?
An overshoot in the position signal that grows over time in your THORLABS Scanner may be due to a power supply that cannot deliver enough current for the intended application. Choose a power supply that can deliver adequate current.
What causes THORLABS GVS012 mirror to shoot off to one side?
If the THORLABS Scanner mirror periodically shoots off to one side and then stops, it could be due to the position sensing circuitry not functioning correctly. Check and repair the position sensing circuitry. Alternatively, the motor cable may be incorrectly wired; inspect and rewire it properly.
How to stop oscillation in THORLABS Scanner galvo motor current?
Oscillation in the THORLABS Scanner galvo motor current can be caused by crosstalk between the position sensing circuitry and the motor drive current. Reposition the motor drive cable. Also, use separate shielded cables for the position sensing and motor drive signals.
Why is there cross talk between axes in my THORLABS GVS012 Scanner?
Cross talk between axes can occur if both motors run off the same power supply, which cannot deliver peak currents. Choose a different power supply with sufficient peak drive current capability to test.
