1) Cannot be Auto reset via 14-20 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 (Par. E-1# [1]). The original event that caused an alarm cannot damage the
adjustable frequency drive or cause dangerous conditions. A trip lock is an action that occurs in conjunction with an alarm,
which may cause damage to the adjustable frequency drive or connected parts. A trip lock situation can only be reset by
power cycling.
