Output phase supervision

What does 11 mean?

The drive's current measurement system indicates no current flowing in one of the motor phases. This suggests a problem with the motor cable connection, a break in the cable, or an issue within the motor itself, such as an open winding. Operating the drive with a missing output phase can severely damage both the motor and the drive's inverter section.

Complete Troubleshooting Guide

1. 1

   Inspect all motor cables for breaks, damage, or loose connections at both the drive's output terminals and the motor terminals.

2. 2

   Perform continuity and insulation resistance tests on the motor windings to identify any internal motor faults.
