5.4.3 Fault Descriptions and Corrective Actions
Table 5.6 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 ➁ 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. Restart procedure.
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.
Drive
OverLoad 64 Drive rating of 110% for 1
minute or 150% for 3 seconds
has been exceeded. Reduce load or extend Accel
Time (140).
Excessive
Load 79 Motor did not come up to
speed in the allotted time. 1. Uncouple load from motor.
2. Repeat Autotune (61).
FluxAmpsRef
Rang 78 The value for flux amps
determined by the autotune
procedure exceeds the
programmed Motor NP FLA
(42). 1. Reprogram Motor NP FLA
(42) with the correct motor
nameplate value.
2. Repeat Autotune (61).
