Diagnostics and Troubleshooting
Diagnostic Display
The diagnostic display on the front of the drive shows drive 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 will respond to motion commands. Commands will not cause
motion unless the decimal point is “On”.
