YASKAWA FSDrive-MV1000 - Fault, Alarm and Error Displays

5.3 Types of Faults, Alarms, and Errors
114 YASKAWA ELECTRIC EZZ010928 FSDrive-MV1000 Instructions
◆ 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 Minor Faults
and Alarms on page 115 in this case. To give an example, there are two types of indication for oS (Overspeed), one
being a fault and the other a minor fault.
