Type Fault Description
➀
Auto-Reset/Run When this type of fault occurs, and A092 [Auto Rstrt Tries] is
set to a value greater than “0,” a user-configurable timer, A093
[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.
➁
Non-Resetable This type of fault may require drive or motor repair, or is
caused by wiring or programing errors. The cause of the fault
must be corrected before the fault can be cleared.
