Reset Mode
A trip is the action when an alarm has appeared. The trip will coast the
motor and can be reset by pressing the reset button or make a reset by
a digital input (parameter group 5-1* [1]). The original event that
caused an alarm cannot damage the frequency converter or cause dan-
gerous conditions. A trip lock is an action when an alarm occurs, which
may cause damage to frequency converter or connected parts. A Trip
Lock situation can only be reset by a power cycling.
