POSSIBLE CAUSE
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 Detect 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. a legal Model_Number, and a fault is
3. Controller defective.
1. Dual Motor Enable parameter is set On Set: When the Dual Drive software is
and Control Mode Select parameter
not set to 1 (Speed Mode Express)
or 2 (Speed Mode).
2. Motor Technology and Feedback
Type parameters do not match.

SET/CLEAR CONDITIONS
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: Activate the throttle.
Set: Encoder Fault (Code 36) or Stall
Detect Fault (Code 73) was activated,
and Brake or Interlock has been applied
to activate LOS control mode, allowing
limited motor control.
Clear: Cycle KSI or, if LOS mode was acti-
vated by the Stall 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 cycles, a check is made to confirm
issued if one is not found.
Clear: Download appropriate software
for your controller model.
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 Tech-
nology=1 must be paired with Feedback
Type=2; otherwise this fault is set.
Clear: Adjust parameters to appropriate
values and cycle KSI.
