Faults
A fault is a condition that stops the drive. There are two fault types.
When this type of fault occurs, and A451 [Auto Rstrt Tries] is set to a value greater than “0,” a user-
configurable timer, A452 [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.
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.
