This alarm occurs when current trouble or current detection trouble occur (when trouble judgment current is detected in the primary or secondary current, or when an instantaneous secondary current of 18A* or higher is detected).
* Changed to output error by current regardless of the inverter frequency.
  In addition, there are 6 horsepower and 10 horsepower compressors.

1. When more than the over-current values shown in the table were detected in the primary and secondary current.
