8.4 Warning and Alarm Types
The drive software issues warnings and alarms to assist in
diagnosing issues. The warning or alarm number appears
in the LCP.
Warning
A warning indicates the drive has encountered an
abnormal operating condition that leads to an alarm. A
warning stops when the abnormal condition is removed or
resolved.
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]/[Off/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 fixed, cycle the input power before resetting the drive.
