Input line supervision

What does 10 mean?

The drive has detected a missing phase in the incoming AC supply voltage. This typically indicates a power supply issue, such as a blown input fuse, a tripped circuit breaker, or a disconnected supply cable. Operating the drive with a missing input phase can lead to internal damage, particularly to the input rectifier bridge.

Complete Troubleshooting Guide

1. 1

   Check the incoming supply voltage at the drive's input terminals to ensure all phases are present.

2. 2

   Inspect all input fuses for continuity and replace any blown fuses.

3. 3

   Examine the supply cables and connections for looseness, damage, or disconnections.
