When the overload pre-alarm state is valid, the working current of the drive exceeds
the overload detection level and hold time exceeds the overload detection time.

Note:
1. Generally, the overload pre-alarm detection level shall be set below the overload
protection level.
2. Within the overload pre-alarm detection time, after the working current is less than
the overload pre-alarm detection level, the overload pre-alarm detection time in the
machine will recounted.
