Line phase failure

What does F6.1 mean?

A missing line phase, periodically low DC link voltage, or inadequate line voltage quality has been detected in the incoming AC supply. This can lead to imbalanced motor operation, reduced torque, and potential damage to the inverter's input rectifier section if not addressed.

Complete Troubleshooting Guide

1. 1

   Check the integrity of the supply system cables for breaks, loose connections, or damage.

2. 2

   Verify the configuration of the supply system, ensuring all phases are present and correctly wired.

3. 3

   Inspect fuses and contactors in the supply line for proper functioning and replace any defective components.
