Table 6.1 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 [Reset]
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.
