AF9ZP0BA - EPS-ACW REACH TRUCK - User Manual
Page - 71/90
- Cause:
This warning occurs when Hardware Setting 0-POS TEACHING
has been turned ON (and the key recycled).
- Remedy:
Turn off the key.
28) SLAVE ALARM XX
Warning with eps off 0xFFED=237 [M]:
- Cause:
When SuC raises an alarm it cuts off the power stage and
steering motor cannot be actuated anymore. Then MuC raises
this warning. In the Zapi console, MuC specifies the LSByte of
the SuC alarm code on the XX position. For instances:
1. LOGIC FAILURE #4:
SLAVE ALARM 10
2. OUTPUT MISMATCH:
SLAVE ALARM D0
3. INPUT MISMATCH:
SLAVE ALARM FA
4. SP MISMATCH:
SLAVE ALARM CF
- Remedy:
If it is repetitive, it reports a problem in the controller.
29) CAN BUS KO
Alarm 0xFFF7 Group #3=247 [M,S]:
- Cause:
Both MuC and SuC lack of the Traction Can Bus messages
(Can ID 0x388 for MuC and 0x389 for SuC) longer than
200msec, this alarm occurs.
- Remedy:
Problem can be in a wrong Can Bus connection, traction
controller switched off or not mounted. Identification of the root
of the problem needs a Can Bus analyzer.
30) EPS NOT ALIGNED
Warning 0xFFEE=238 with eps on and no drive [M,S]:
- Cause:
This warning occurs at key on in three ways:
1. No edge on the straight ahead switch (SW1 on CNA#12)
longer than 3secs
OR
2. No edge on the straight ahead switch (SW1 on CNA#12)
within 180 degrees rotation of the MDU
OR
3. The encoder is not able to return to the 0 degrees position
(straight ahead) after the edge on SW1 has been detected.
Remedy:
STATUS #2 Selfchecking routine helps to found the root of the
problem. This
31) INIT VMN NOT OK
Alarm 0xFFFB=251 Group #0 [M]:
- Cause:
After key-on, with the three phase power bridge off, the DC bus
voltage is expected to raises up to 14Vdc within 3.2secs (alarm
CAPACITOR CHARGE below if it isn’t). In the same time,
steering controller monitors the common voltage at the motor
terminals (see STATUS #5 1ST value in Fig 15.31-1) and raises
this alarm when the 3.2secs time-out is expired and:
a) the common voltage is lower than 7Vdc (bottom power
mosfet shortcircuited to –B).
OR
b) the common voltage is stuck to the DC Bus (top power
mosfet shorcircuited to +B). (It is considered stuck in case it is
in a window of +/- 1Vdc around the DC Bus).
STATUS #5 in the TESTER menu, supplies the real time value
