Table 9.3 Alarm/Warning Code List
A trip is the action when an alarm has appeared. The trip coasts the motor and can be reset by pressing [Reset] or make a
reset by a digital input (parameter group 5-1* Digital Inputs [1] Reset). 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.
