Table 4.1 Alarm/Warning code list
(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 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.
