Cause : Motor stall comes when motor is operating in stall region because of e.g. excessive load or insufficient motor power.

The fault code 7121 in your ABB ACS560 drive indicates a motor stall. This means the motor connected to the drive is unable to rotate or is experiencing excessive load.

  1. Check motor load and drive ratings.
  2. Check fault function parameters.
