Initialization Error Grid Detection

What does 45 mean?

This fault indicates that the MOVIFIT unit was unable to automatically detect or recognize the sequence of the incoming three-phase power supply during its initialization phase. This prevents the unit from starting correctly and is typically due to incorrect wiring of the grid connection (L1, L2, L3). An unrecognized phase sequence can lead to motors rotating in the wrong direction, damage to mechanical components, or unit malfunction, requiring immediate correction before operation.

Complete Troubleshooting Guide

1. 1

   Verify the three-phase grid connection to the MOVIFIT unit, ensuring L1, L2, and L3 are correctly wired to their respective terminals.

2. 2

   Confirm that a stable and balanced three-phase power supply is present and properly connected to the unit's input terminals using a multimeter.

3. 3

   Check for any loose connections or damaged wiring in the entire grid connection path leading to the MOVIFIT unit.
