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 Ta bl e 2 0
.
Table 20 - Fault Types
The drive indicates faults in the following ways:
• Status LEDs on the drive control panel (see Determining Drive Status
Using the Status LEDs on page 196).
• Drive status parameters Drive Status 1 (209) and Drive Status 2 (210).
• Entries in the fault queue (see About the Fault Queue
on page 202).
• Pop-up screen on the OIM. See Figure 81
. The screen displays:
– Fault number
– Fault name
– Time that has elapsed since fault occurred.
No.

Fault Description
1 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 resets and the drive
restarts.
2 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 resets on power up after repair.
3 User-Configurable These faults can be enabled/disabled to either annunciate or ignore a fault condition
using Fault Config 1 (238).
4 Normal Fault The fault is resettable using normal fault clearing mechanisms on the drive (Stop/
Reset button, powercycling, etc.) or through VS Utilities.
