correctly
，
set correctly with AUX FUNCTION 11 (see12.4.1.9), And check motor bearing sensor (encoder)
whether slip (bearing sensor has two loop connection: one connects rotor shaft; another connecs electric
cabinet) or not, no slip, check if the two road rate differential wiring structure reliable connect or not.
6) STEER SENSOR KO
CAN Bus code =84
-
Cause:
If the jitter range of instructions(CPOC1 on CNA#9 or CPOC2 on CNA#8)
to potentiometer is more than MAX SP SLOPE (see 12.4.6.3) will cause fault.
The fault is often due to potentiomete rprovides discontinuous voltage
signal
。
-
Handle:
Replace two-way potentiometer
7) JERKING FB POT
CAN Bus code =223
-
Cause: numerical changes of feedback potentiometer in 16 milliseconds jitters greater
than 0.3 V will failure. Failure is often due to a discrete output voltage signal of feedback
potentiometer.
。
- Handle:
Change the feedback potentiometer.
8) FB POT LOCKED or FB SENS LOCKED CAN
Bus code =222
- Cause:
The application of a feedback potentiometer, adjust potentiometer
numerical but feedback potentiometer (CPOT on CNB# 6) also don't
change (or opposite direction change), at this time will failure
。
In the application of trigger switch, set ENCODER CONTROL to off, t
controls the change of ,potentiometer but feedback ENCODER
potentiometer is not calculated value change, at this time will failure
。
- Treatment: In the application of trigger switch, check if the encoder is mechanical
loose or not and steering wheel has choking phenomenon or not.
Make sure that the wiper is not beyond the maximum machinery
limitation of steering wheel.
。
In addition, fault may occur in the installation, when the motor rotation
direction is not the same with the expected direction .
。
In the application of trigger switch, check if the encoder is mechanical
loose or not and steering wheel has choking phenomenon or not.
。
It is easy to solve the problem
，
set DEBUG OUTPUT to 11 (see 12.4.6.4).
9) STEPPER MOTOR MISM
CAN Bus code =219
-
Cause: when the attachment frequency of stepping motor is not match with
differential pressure will be fault.
。
(such as
：
There is high differential pressure but low frequency of connection between D and
Q of stepping motor). when the step motor difference increases in normal
conditions , the stepping motor frequency also will be increase
subsequently.
- Treatment: Need to change the controller.
10) ENCODER ERROR
CAN Bus code =241
- Cause:
When ENCODER CONTROL sets up to ON. The actual frequency can't
reach a set frequency will be alarm
。
- Treatment:
Since the two conditions of individual exists
：
encoder resolution is
not match with the actual encoder,or there is wrong connection of
two encoder galleries.the new way is connecting two encoder
galleries.
11) BAD ENCODER SIGN
