Overcurrent

What does 1 mean?

The frequency converter has detected a current exceeding 4 times the nominal current (4*IH) in the motor cable. This can be caused by a sudden heavy load increase, a short circuit in the motor cables, or an unsuitable motor. Ignoring this can lead to drive shutdown and potential damage to motor or drive components.
