Allen-Bradley Drive Fault Codes
Description
DC Bus voltage remains below
85% nominal for longer than .5
seconds.
DC Bus voltage fell below
minimum.
DC Bus maximum voltage
exceeded.
Motor has stalled. Motor load is
excessive.
Internal electronic overload trip.
Excessive motor load exists.
Excessive heat detected by
heatsink transducer.
Overcurrent detected in
instantaneous hardware trip circuit.
DC Bus regulation prevents
machine from decelerating
typically due to high input voltage,
motor regeneration or unstable
motor operation.
Controller failed to reset fault
within the number of retries.
Phase-to-ground fault detected
between controller and motor in
Phase U.

Corrective Action/
Remarks
Monitor incoming AC line for low voltage or line power
interruption.
Monitor AC incoming AC line for low voltage or line
power interruption.
Monitor the AC line for high line voltage or transient
conditions. High voltage can result from motor
regeneration. Buck transformer may be required.
Check motor wiring and connection terminals. Check wash
basket freedom of movement and excess belt tension.
Check motor wiring and connection terminals. Check wash
basket freedom of movement and excess belt tension.
Clear blocked or dirty heatsink fins. Check ambient
temperature. Check for blocked or nonoperating fan.
Check short circuit at the controller output or excessive
load conditions at motor.
Verify DC Bus (d005) is less than 340V for 200-240V
applications or 680V for 380-480V applications. Check for
an imbalanced wash load. Check for proper speed
increment through all extract speeds.
Fault exists that must be corrected before further operation.
Check "Fault Buffer 1" on 1305 and 1336 for specific fault
that triggered max retries fault.
Check wiring between the drive and motor. Check for
grounded phase.
