A trip is the action when an alarm has appeared. The trip
coasts the motor and can be reset by pressing [Reset] or
by using the Reset function via a digital input (parameter
group 5-1* Digital Inputs [1]). The original event that
caused an alarm cannot damage the adjustable frequency
drive or cause dangerous conditions. A trip lock is an
action when an alarm occurs, which may damage the
adjustable frequency drive or connected parts. A trip lock
situation can only be reset by power cycling.
