Allen-Bradley Drive Fault Codes
Fault Description
Corrective Action/
Remarks
03 Power Loss Fault DC Bus voltage remains below
85% nominal for longer than .5
seconds. Monitor incoming AC line for low voltage or line power
interruption.
04 Under Voltage Fault DC Bus voltage fell below
minimum. Monitor AC incoming AC line for low voltage or line
power interruption.
05 Over Voltage Fault DC Bus maximum voltage
exceeded. Monitor the AC line for high line voltage or transient
conditions. High voltage can result from motor
regeneration. Buck transformer may be required.
06 Motor Stall Motor has stalled. Motor load is
excessive. Check motor wiring and connection terminals. Check wash
basket freedom of movement and excess belt tension.
07 Motor Overload Fault Internal electronic overload trip.
Excessive motor load exists. Check motor wiring and connection terminals. Check wash
basket freedom of movement and excess belt tension.
08 Over Temperature Fault Excessive heat detected by
heatsink transducer. Clear blocked or dirty heatsink fins. Check ambient
temperature. Check for blocked or nonoperating fan.
10 Serial Fault Drive lost communication with
controlling device. HIM removed while power applied, cycle power to clear.
12 Overcurrent Fault Overcurrent detected in
instantaneous hardware trip circuit. Check short circuit at the controller output or excessive
load conditions at motor.
22 Controller Reset Fault Stop input not present. Check stop input into control terminal board. Close door
and ensure any jumpers are placed correctly.
32 EEPROM Fault EEProm has invalid data. Consult the factory for further instructions.
33 Max Retries Fault Controller failed to reset fault
within the number of retries. 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.
38 Phase U Fault Phase-to-ground fault detected
between controller and motor in
Phase U. Check wiring between the drive and motor. Check for
grounded phase.
