MOTOR FAULT CODES (8 OF 8)
POSSIBLE CAUSE
1. The VCL software in the controller
does not match the OS software in the
controller.
1. Vehicle movement sensed after the EM
Brake has been commanded to set.
2. EM Brake will not hold the motor from
rotating.
1. Limited Operating Strategy (LOS) control
mode has been activated, as a result of
either an Encoder Fault (Code 36) or a
Stall Detected fault (Code 73).
2. Motor encoder failure.
3. Bad crimps or faulty wiring.
4. Vehicle is stalled.
1. Emergency Reverse was activated and
concluded because the EMR Timeout
timer has expired.
2. The emergency reverse input is stuck
On.
1. Model_Number variable contains illegal
value.
2. Software and hardware do not match.
3. Controller defective.
1. Dual drive enabled on only one controller.
2. Incorrect position feedback type chosen
for motor technology in use.
3. Dual drive is enabled in torque mode.
TROUBLESHOOTING
SET / CLEAR CONDITIONS
Set: VCL and OS software do not match; when KSI
cycles, a check is made to verify that they match
and a fault is issued when they do not.
Clear: Download the correct VCL and OS software
into the controller.
Set: After the EM Brake was commanded to set
and time has elapsed to allow the brake to fully
engage, vehicle movement has been sensed.
Clear: 1. Activate the Throttle (EM Brake type 2).
2. Activate the Interlock (EM Brake type 1).
Set: Encoder Fault (code 36) or Stall Detected (code
73) was activated, if parameter LOS Upon Encoder
Fault = On and Interlock has been cycled, then the
Encoder LOS (code 93) control mode is activated,
allowing limited motor control.
Clear: Cycle KSI or, if LOS mode was activated by
the Stall Detected fault, clear by ensuring encoder
senses proper operation, Motor RPM = 0, and
Throttle Command = 0.
Set: Emergency Reverse was activated and ran
until the EMR Timeout timer expired.
Clear: Turn the emergency reverse input Off.
Set: Illegal Model_Number variable; when KSI
Number, and a fault is issued if one is not found.
Clear: Download appropriate software for your
controller model.
Set: When the Dual Drive software is enabled,
the controller must be set to either Speed Mode
Express or Speed Mode; otherwise this fault is set.
Motor Techology=0 must be paired with Feedback
Type=1, and Motor Technology=1 must be paired
with Feedback Type=2; otherwise this fault is set.
Clear: Adjust parameters to appropriate values and
cycle KSI.
