Fault Type Fault Description
➀ Auto-Reset Run When this type of fault occurs, and [Auto Rstrt Tries] ( page 98 ) is set to a value
greater than ‘0’, a user-configurable timer, [Auto Rstrt Delay] ( page 98 ) begins.
When the timer reaches zero, the AFE attempts to automatically reset the fault.
If the condition that caused the fault is no longer present, the fault is reset and
the AFE is restarted.
➁ Non-Resettable This type of fault normally requires AFE or motor repair. The cause of the fault
must be corrected before the fault can be cleared. After repair, the fault is reset
on power up.
➂ User Configurable These faults can be enabled and disabled to annunciate or ignore a fault
condition by using [Fault Config] (
page 105 ).
