Cause : Motor Pull Out or Step Out Detection comes when motor pull out or step out has occurred. Motor has exceeded its pull-out torque.

  1. Load is too heavy.
  2. Increase the load inertia for PM motor (n8-55).
  3. Increase the pull-in current during accel/decel (n8-51).
  4. Reduce the load.
  5. Increase the motor or drive capacity.
