Type Fault Description
1 Auto-Reset Run When this type of fault occurs, and [Auto Rstrt Tries] (see page 41) is set to a value
greater than “0,” a user-configurable timer, [Auto Rstrt Delay] (see page 41
) begins.
When the timer reaches zero, the drive attempts to automatically reset the fault. If the
condition that caused the fault is no longer present, the fault will be reset and the drive
will be restarted.
2 Non-Resettable This type of fault normally requires drive or motor repair. The cause of the fault must be
corrected before the fault can be cleared. The fault will be reset on power up after
repair.
3 User Configurable These faults can be enabled/disabled to annunciate or ignore a fault condition.
Type Alarm Description
1 User Configurable These alarms can be enabled or disabled through [Alarm Config 1] on page 53
.
2 Non-Configurable These alarms are always enabled.
