F17 (MMX/MMV): Encoder Tracking
Code Meaning: The motor is not running as the drive is commanding.
Further Information/Troubleshooting Tips:
This is a code that will only appear on older drive models. First check the encoder coupling. Make sure it is not loose and make sure the encoder does not tilt or wobble while the motor is being driven. Tighten couplings and brackets as necessary. If the physical elements of the encoder appear fine, and you are still seeing this code, call PE® for further assistance.
