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 equipments. After the faults are fixed,
the input power must be cycled before the reset of the
frequency converter.
