Output Phase Supervision

What does 11 mean?

This fault indicates that the drive's current measurement system has detected zero current in one of the motor phases. This typically points to a disconnection or malfunction in the motor or its cabling, or an issue with an associated du/dt or sinus filter. Continued operation with a missing phase can lead to motor damage or reduced performance.

Complete Troubleshooting Guide

1. 1

   Inspect the motor cables for damage or loose connections, and verify the motor's integrity.

2. 2

   Check the du/dt or sinus filters for proper function and signs of malfunction.
