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