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 6 Overcurrent parameter.
Note: Driver 6 is a digital (On/Off) 1
Amp output.
Set: Driver 6 is either open or
shorted, or Driver 6 exceeded
its overcurrent setting.
Clear: Correct the open or short,
and then Reset Controller.
