Type Fault Description
1 Auto-Reset/Run When this type of fault occurs, and A163
[Auto Rstrt Tries] is set to a value greater
than “0,” a user-configurable timer, A164 [Auto Rstrt Delay], 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 may require drive or motor repair, or is caused by wiring or
programming errors. The cause of the fault must be corrected before the fault can be
cleared.
