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.
