Fault Type(s):
1 = MotorSpeed did not
ramp down fast enough
to meet conguration
(set by Interlock_Brake_
Supervision_Ramp_Delay
and Interlock_Brake_
Superivsion_Ramp_Rate).
2 = Vehicle brought to stop,
but then EM brake (if
congured) failed to set.
3 = Vehicle brought to stop,
but then traversed a
distance beyond that
set by Interlock_Brake_
Supervision_Position_
Settling_Limit.
1. For 1, ramp rate/time set too
conservatively (needs to be set for
worst case braking (full load) to
prevent false trip).
2. The vehicle could have a full
battery due to which regen is
limited and cannot decelerate fast
enough.
3. For 2, check EM Brake< for
failures/wear.
Set: The interlock brake
supervision function, when
enabled, monitors the vehicle
speed during interlock
braking to ensure the vehicle
is decelerating and stops
within the stopping distance.
Clear: Reset Controller.

Fault Type(s): 1
1. During an EMR event, the motor
speed exceeded the limit set
by the Emergency Reverse
Supervision parameters.
2. See Programmer » Application

Emergency Reverse Supervision.
Set: During an EMR event, the
motor speed exceeded the limit
set by the Emergency Reverse
Supervision parameters.

Fault Type(s):
1 = Driver current exceeded
hardware limits.
2 = Driver current exceeded
congured over-current limits.
3 = Driver commanded PWM
active, using diagnostic
pulses. Voltage measured
high, should be low. Typically
caused by driver failure, or
driver pin short to high.
4 = Driver commanded PWM
active, using diagnostic
pulses. Voltage measured
low, should be high. Either
open circuit, or driver pin
short to ground.
5 = Driver commanded PWM
is 0, and voltage measured
low (should be high). Either
open circuit, or driver pin
short to ground.
7 = Driver undercurrent -
Monitored current is below
undercurrent threshold.
Fault types 1-2 are
always checked.
Fault types 3-5 are only
checked if driver checks
are enabled.
1. Open or short on driver load.
2. Dirty connector pins at controller
or contactor coil.
3. Bad connector crimps or
faulty wiring.
4. Driver overcurrent, as set by the
Driver 1 Overcurrent parameter.
5. See Programmer » Controller
Setup » Outputs » Driver 1 » Driver
1 Overcurrent.
Set: Driver 1 is either open or
shorted, or Driver 1 exceeded
its overcurrent setting.
Clear: Correct the open or short,
and then Reset Controller.
