4.2.3 Fault Descriptions and Corrective Actions
Table 4.5 describes drive faults and corrective actions. It also indicates if the fault is
➀ Auto-resettable
➁ Non-resettable
➂ User-configurable

Description Action
Analog In
Loss 29
➀
➂
An analog input is configured
to fault on signal loss. A signal
loss has occurred.
Configure with Anlg In 1, 2
Loss (324, 327).
1. Check parameters.
2. Check for broken/loose
connections at inputs.
Anlg Cal
Chksum 108 The checksum read from the
analog calibration data does
not match the checksum
calculated. Replace drive.
Auto Rstrt
Tries 33
➂
Drive unsuccessfully
attempted to reset a fault and
resume running for the
programmed number of Auto
Rstrt Tries (174).
Enable/disable with Fault
Config 1 (238).
Correct the cause of the fault
and manually clear.
AutoTune
Aborted 80 The autotune procedure was
canceled by the user or a fault
occurred. Restart procedure.
Auxiliary
Input 2
➀
Input is open. Check remote wiring.
Cntl Bd
Overtemp 55 The temperature sensor on
the Main Control Board
detected excessive heat. 1. Check Main Control Board
fan.
2. Check surrounding air
temperature.
3. Verify proper
mounting/cooling.
DB
Resistance 69 Resistance of the internal DB
resistor is out of range. Replace resistor.
Decel Inhibit 24
➂
The drive is not following a
commanded deceleration
because it is attempting to limit
bus voltage. 1. Verify input voltage is within
drive specified limits.
2. Verify system ground
impedance follows proper
grounding techniques.
3. Disable bus regulation
and/or add dynamic brake
resistor and/or extend
deceleration time.
