Code Description Comments
3-032 EM Brake Fault The brake coil is either opened or shorted.
3-036 Encoder Fault Unexpected result from the motor encoder. Output disabled. Check to make
sure either motor power or encoder wires are not reversed or disconnected.
3-037 Motor Open One of the phases to the motor is open.
3-038 K3 Weld The K3 contacts are detected closed when not commanded. May also occur if
a motor phase is disconnected.
3-039 K3 Contact Open The K3 is not providing power when commanded.
3-041 Pedal Open The throttle pot wiper voltage is too high.
3-042 Pedal Short The throttle pot wiper voltage is too low
3-045 Pot Low Overcurrent The pot low current exceeds 10 mA.
3-046 EEPROM Fault The controller operating system tried to write to EEPROM memory and failed.
3-047 HPD Fault KSI, interlock, direction, and throttle inputs applied in incorrect sequence.
3-049 Parameter Change The main controller commanded a parameter change. The drive is disabled
until KSI is cycled.
3-051 Pedal Disable The throttle was detected active on power-up. Throttle will be disabled.
3-052 Throttle active while
off seat
(Won’t be displayed on screen) The throttle was not at neutral when the
operator left the seat longer than the seat switch debounce time.
3-053 Push Too Fast Fault (Won’t be displayed on screen) The wheel speed while in push mode is
detected too high. The drive controller will activate to reduce wheel speed.
3-054 Throttle active with
CAN interlock off
(Won’t be displayed on screen) The throttle was not in neutral when the
interlock signal on the CAN Bus was not enabled.
3-055 E-Stop (Won’t be displayed on screen) The E-stop was pressed while in motion. The
controller will decelerate the machine and set the EM brake.
3-056 Low BDI Low Battery Discharge Indicator. Drive power is reduced.
3-057 EM Brake Type The EM brake type is incorrectly set in programming
3-058 Throttle Active with
E-Stop
(Won’t be displayed on screen) The E-stop was pressed while the throttle was
active. The machine will be slowed and stopped by the controller.
3-059 Throttle Forward Max
Calibration
(Won’t be displayed on screen) The throttle maximum position during
calibration is less than the deadband.
3-061 Throttle Reverse Max
Calibration
3-062 Throttle Neutral
Deadband Calibration
(Won’t be displayed on screen) Unexpected results for neutral deadband
calibration
3-063 Throttle Calibration
Incomplete
(Won’t be displayed on screen) the throttle calibration was started but not
completed.
3-064 Throttle Calibration
with Active Pot Fault
(Won’t be displayed on screen) The throttle calibration was attempted while the
3-041 or 3-042 error conditions were set.
3-065 Multiple Throttle
Calibrations Active
(Won’t be displayed on screen) This is a programming error that should not be
encountered.
3-068 VCL Fault Vehicle Control Language fault. Internal software error.
3-069 Supply Fault The internal 5 or 12 volt power supplies are out of range.
3-071 OS General Internal controller fault
3-072 PDO Timeout The time between CAN PDO messages received exceeded the timeout period.
3-073 Stall No motor encoder movement detected.
