Effect of fault
Possible Cause Note
44
Brake Wiper Low
Full brake.
1. See note, voltage too low on pin-17 Not used – If fault occurs
then check controller
connector for
contamination
45
Pot Low Overcurrent
Shutdown throttle;
Full brake.
1. Current into pin-18 exceeded 0.010A Not used – If fault occurs
then check controller
connector for
contamination.
46
EEPROM Failure
Shutdown main contactor;
Shutdown motor;
Shutdown EM bake;
Shutdown Throttle;
Shutdown interlock
Shutdown Driver 1;
Shutdown Driver 2;
Shutdown Driver 3
Shutdown Driver 4;
Shutdown PD;
Full brake.
1. Controller parameters corrupted. Controller must be
returned to factory for
reprogramming.
47
HPD/Sequencing Fault
Shutdown throttle.
1. Startup switches not operated in the
correct order.
2. Faulty wiring or switches.
Refer to operator section
for correct startup
sequence.
49
Parameter Change Fault
Shutdown main contactor;
Shutdown motor;
Shutdown EM bake.
1. May occur when adjusting parameters. Cycle key switch to clear
fault.
68
VCL Runtime Error
Shutdown main contactor;
Shutdown motor;
Shutdown EM bake;
Shutdown Throttle;
Shutdown interlock
Shutdown Driver 1;
Shutdown Driver 2;
Shutdown Driver 3
Shutdown Driver 4;
Shutdown PD;
Full brake.
1. Controller parameters corrupted. Controller must be
returned to factory for
reprogramming.
69
External Supply Out of Range
None.
1. Faulty wiring.
2. Faulty motor encoder.
3. Faulty dash display.
Excessive combined
current into pin-26 and
pin-25.
71
OS General
Shutdown main contactor;
Shutdown motor;
Shutdown EM bake;
Shutdown Throttle;
Shutdown interlock
Shutdown Driver 1;
Shutdown Driver 2;
Shutdown Driver 3
Shutdown Driver 4;
Shutdown PD;
Full brake.
1. Internal controller fault. If cycle key switch does not
clear fault, controller may
have failed.
72
PDO Timeout
Shutdown interlock;
CAN NMT State set to Pre-operational
1. Internal controller fault. Cycle key switch to clear
fault.
73
Stall Detect
Control mode changed to LOS.
1. Stalled motor.
2. Faulty motor encoder.
3. Faulty wiring to encoder.
4. Encoder power supply fault.
Encoder power supply is
provided by pin-26 from
controller.
