7 Diagnostics and Troubleshooting

7.1 Warning and Alarm Types

Warning/ Description
alarm type
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 frequency converter
after an alarm.
Reset the frequency converter in any of 4 ways:
•
Press [Reset].
•
Digital reset input command.
•
Serial communication reset input command.
•
Auto reset.
Trip
A trip is an action by the frequency converter to suspend
operation to prevent damages 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
A trip lock is an action by the frequency converter to
suspend operation to prevent damages 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 fixed,
cycle the input power before resetting the frequency
converter.
