EFFECT OF FAULT
POSSIBLE CAUSE SET / CLEAR CONDITIONS
73 Stall Detected
ShutdownEMBrake;
Motor disabled;
Control Mode changed to LOS
(Limited Operating Strategy).
1. Stalled motor.
2. Motor encoder failure.
3. Bad crimps or faulty wiring.
4. Problems with power supply for the
motor encoder.
5. See Monitor menu » Motor: Motor RPM.
Set: No motor encoder movement detected.
Clear: Either cycle KSI, or if parameter LOS Upon
Encoder Fault = On and Interlock has been cycled,
then the Stall Detected fault is cleared and Encoder
LOS fault (code 93) is set, allowing limited motor
control.
74 Fault On Other Traction

FullBrake.
1. The Supervisor has detected a mismatch
in redundant readings.
2. Internal damage to Supervisor
microprocessor.
3. Switch inputs allowed to be within
upper and lower thresholds for over 100
milliseconds. (for recurring errors, check
the switches for moisture).
Set: Mismatched redundant readings; damaged
Supervisor; illegal switch inputs.
Clear: Check for noise or voltage drift in all switch
inputs; check connections; cycle KSI.
