Overcurrent

What does 1 mean?

The frequency converter has detected a motor current exceeding 4 times the nominal current (I_H). This condition can result from a sudden heavy load increase, a short circuit in the motor cables, or an unsuitable motor for the drive. Subcodes indicate hardware trip, current cutter, or current controller supervision.
