3) POWER FAILURE #2
CAN Bus code = 72
- Cause:
Motor start to operation,but motor U phase current is 0,then fault alarm.
- Handle:
Check the power insurance is normal or not. Check the battery and the
wiring of positive controller. Check the wiring of motor U phase. Otherwise
need to replace controller
。
4) POWER FAILURE #3
CAN Bus code = 71
- Cause:
Motor start to operation,but motor V phase current is 0,then fault alarm.
。
- Handle:
heck the power insurance is normal or not. Check the battery and the
wiring of positive controller. Check the wiring of motor V phase.
Otherwise need to replace controller.
5) LOGIC FAILURE #1
CAN Bus code = 19
- Cause:
When practical voltage of the interphase motor of between W and U are
different with expected value ,fault alarm.
- Handle:
Should replace the controller .
6) LOGIC FAILURE #2
CAN Bus code = 18
- Cause:
When practical voltage of the interphase motor of between W and U a
different with expected value ,fault alarm.
- Handle:
Should replace the controller.
7) MAIN CONT. OPEN
CAN Bus code = 48
- Cause:
when CAN BUS is set by PRESENT causes fault.
Contactor close is controlled by traction controller
，
eps-ac0 outstanding
messege through CAN.If this information lacks more than about 1.5 secs, this
alarm occurs. If there is no information transmission more than 1.5 seconds,
may cuase fault.
- Handle:
The cause of the problem is the traction control of the main contactor in
the open
8) CAN BUS KO
CAN Bus code = 247
- Cause:
when CAN BUS is set by PRESENT causes fault
。
.
Eps-ac0 Must receive all information of traction controller.
。
If there is no
information transmission more than 1.5 seconds, may cuase fault.
- Handle:
Check the CAN Bus communication system
，
analysis structure of
traction controller turn to steering.
9) MOTOR LOCKED
CAN Bus code = 220
-
Cause:
. Motor current keep close to maximum current time more than
1 second, there will be an fault alarm.
。
-
Handle: Check if motor has mechanical lock or not , Simple method is to DEBUG
OUTPUT Settings for 11
(see12.4.6.4).
14.1.3 Trouble light flickers 3 times.
1) D LINE SENSOR KO
CAN Bus code = 243
- Cause:
When the average voltage of step motor(join CNA#9) is not zero cuases
fault: Stepping motor voltage is a sine wave of total null voltage .
-
Handle : Check the step motor connection,especially resistance measurement between CNA# 9 and
