No-Load Current Fault

What does Er - 05 mean?

During Auto-Tuning, this fault signifies that the process did not complete within the specified time or the measured no-load current was outside the expected range. This can be caused by incorrect motor data, wiring issues, or a connected load influencing the no-load measurement. An incorrect no-load current value will lead to suboptimal motor parameterization and control.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the motor is connected to a mechanical load, disconnect it and re-attempt Auto-Tuning to ensure an accurate no-load current measurement.
