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

5.3 Types of Faults, Alarms, and Errors

◆ Fault, Alarm and Error Displays

Faults (Drive Faults and Power Cell Faults)
■
When the drive detects a fault, the code indicated by the digital operator lights continuously rather than flashing, and the
ALM indicator LED also lights continuously. A flashing indication means a minor fault or alarm; refer to
and Alarms on page 115
being a fault and the other a minor fault.
