Diagnostics and Troubleshooting
Diagnostic Display
The diagnostic display on the front of the drive shows drive, base drive and FM-2 Module status and fault codes. When a fault
condition occurs, the drive will display the fault code, overriding the status code.
The decimal point is “On” when the drive is enabled and the stop input is not active. This indicates that the drive is ready to
run and any motion command will cause motion. Motion commands will not cause motion unless you are Ready (R) and the
decimal point is “On”.
