About Faults

Faults indicate conditions within the drive that require immediate attention. The drive
responds to a fault by initiating a coast-to-stop sequence and turning off output power
to the motor.

In addition, some faults are auto-resettable, non-resettable, and/or user-configurable
as described in table 5.5.

Fault Description

Auto-Reset/Run

If the drive is running when this type of fault occurs, and
Auto Rstrt Tries (174) is set to a value greater than 0, a
user-configurable timer, Auto Rstrt Delay (175) 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.

Non-Resettable

This type of fault normally requires drive or motor repair.
The cause of the fault must be corrected before the fault
can be cleared. The fault will be reset on power up after
repair.

User-Configurable

These faults can be enabled/disabled to either annunciate
or ignore a fault condition using Fault Config 1 (238).
