Fault Types
Type Fault Description
1 Auto-Reset/Run When this type of fault occurs, and A541
[Auto Rstrt Tries] is set to a value greater than
“0,” a user-configurable timer, A542 [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.
