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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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