(X) Dependent on parameter
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 dangerous
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.
