What does 56 mean?

The Automatic Motor Adaptation (AMA) process was intentionally stopped by the user. If this was unintentional, it means AMA did not complete its motor characterization. This will prevent the drive from optimizing motor control and protection based on the motor's actual electrical properties.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Confirm the motor is ready for AMA, not overloaded, and has no external faults before restarting.
