Warning/
alarm type
Description
Warning A warning indicates an abnormal operating
condition that leads to an alarm. A warning stops
when the abnormal condition is removed.
Alarm An alarm indicates a fault that requires
immediate attention. The fault always triggers a
trip or trip lock. Reset the drive after an alarm.
Reset the drive in any of 4 ways:
•
Press [Reset]/[O/Reset].
•
Digital reset input command.
•
Serial communication reset input command.
•
Auto reset.
Trip
When tripping, the drive suspends operation to prevent
damage to the drive and other equipment. When a trip
occurs, the motor coasts to a stop. The drive logic
continues to operate and monitor the drive status. After
the fault condition is remedied, the drive is ready for a
reset.
Trip lock
When trip locking, the drive suspends operation to prevent
damage to the drive and other equipment. When a trip
lock occurs, the motor coasts to a stop. The drive logic
continues to operate and monitor the drive status. The
drive starts a trip lock only when serious faults occur that
can damage the drive or other equipment. After the faults
are xed, cycle the input power before resetting the drive.

6.5.1 Warnings/Alarm Messages
A warning or an alarm is signalled by the relevant indicator
light on the front of the frequency converter and indicated
by a code on the display.

motor may still be continued. Warning messages may be
