system. Communication between them requires a stuffing bit
(stuffing bit must be reversed at any new frame). In case the
stuffing bit is frozen longer than 100 ms this alarm occurs.
- Remedy:
If it is repetitive, it reports a problem in the controller
26) TFD STB I HIGH
Warning with E-steering motor controller off 0xFFEC = 236
Group #3 [M,S]:
MAIN CONTACTOR other than OPTION #1 to keep the motor
controller to on.
- Cause:
If the output of the amplifier for measuring the current in the TFD is
not default at rest, this alarm occurs.
Default for MuC is 0.5 V (alarm when it is higher than 1 V). For
MuC output increases when the current is not null.
Default for SuC is 4.5 V (alarm when it is lower than 4 V). For SuC
output decreases when the current is not null.
- Remedy:
It reports a problem in the controller.
27) INPUT MISMATCH
Alarm 0xFFFA = 250 Group #0 [S]:
- Cause:
MuC and SuC read the inputs independently. SuC checks that the
values it is reading match in real time with those the MuC is
reading. SuC raises this alarm in case they are mismatched.
- Remedy:
If it is repetitive, it reports a problem in the controller.
28) SP MISMATCH
Alarm 0xFFCF = 207 Group #0 [S]:
- Cause:
MuC and SuC evaluate independently the speed set point and the
position set point. This alarm is raised by the SuC in case it
evaluates different set points than the MuC.
- Remedy:
If it is repetitive, it reports a problem in the controller.
29) OUTPUT MISMATCH
Alarm 0xFFD0 = 208 Group #0 [S]:
- Cause:
SuC compares the set points of motor current, motor speed and
position with the actual values. If there is a mismatch SuC raises
this alarm. Imax in the motor with the correct sign is an exception:
no alarm in this case.
- Remedy:
If it is repetitive, it reports a problem in the controller.
30) SLAVE ALARM XX
Warning with E-steering motor controller off 0xFFED = 237
[M]:
- Cause:
When SuC raises an alarm, steering motor cannot be actuated.
MuC, by raising this warning, reports that SuC has cut off the
power stage. In the Zapi console, MuC specifies the LSbyte of the
SuC alarm code. For instance, in case of SuC alarm code FFD0
(OUTPUT MISMATCH), MuC raises SLAVE ALARM D0. (i.e. XX
assumes the two last nibbles of the SuC alarm code.)
