Operating Guide
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.
