Overcurrent

What does 1 mean?

The frequency converter has detected a motor current exceeding four times the nominal current (>4*IN) in the motor cable. This condition typically results from a sudden heavy increase in motor load, a short circuit in the motor cables, or the use of an unsuitable motor for the application, posing a risk of damage to the motor or drive.
