Driver 2 Fault
Driver_2_Fault
0x2161
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 2 Overcurrent parameter.
5. See Programmer » Controller
Setup » Outputs » Driver 2 » Driver
2 Overcurrent.
Set: Driver 2 is either open or
shorted, or Driver 2 exceeded
its overcurrent setting.
Clear: Correct the open or short,
and then Reset Controller.
