Fault, Alarm And Error Displays - YASKAWA FSDrive-MV1000 Series Instructions For Use Manual

5.3 Types of Faults, Alarms, and Errors

Table 5.6 gives an overview of possible fault codes. Conditions such as overvoltages can trip faults and alarms. It is
important to distinguish between faults and alarms to determine the proper corrective actions.
When the drive detects a fault, the ALM indicator LED lights continuously and the fault code appears on the digital
operator. An alarm is present if the ALM LED blinks and the fault code on the digital operator flashes.
