Diagnostics and Troubleshooting
Diagnostic Display
The diagnostic segment display on the front of the drive shows drive status, FM-3 module
status, and fault codes. When a fault condition occurs, the drive will display the fault code,
overriding the status code. The alphanumeric display on the FM-3 module provides additional
fault information.
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”.
