Motor Data Fault

What does Er - 01 mean?

This auto-tuning fault indicates an error in the motor data input, a mismatch between motor output and rated current, or an issue with no-load current vs. input motor rated current during vector control auto-tuning. Incorrect motor data prevents the Drive from accurately characterizing the motor, potentially leading to inefficient operation or damage from improper control.

Complete Troubleshooting Guide

1. 1

   Thoroughly verify all Auto-Tuning input data parameters (T1 group) for accuracy, especially motor nameplate details like rated voltage, current, and frequency.

2. 2

   Confirm that the Drive's capacity is compatible with the connected motor's capacity.

3. 3

   Check motor rated current (E2-03) and no-load current (T1-04) settings for correctness and proper relationship.
