occurs in case none of the above failures has been detected
but at least one between the injected currents (Ivw, Iwv, Iwu,
Iuw) is lower than 10Adc (when 14.7Adc are expected instead).
- Remedy:
It reports a generic failure in the controller (power or logic).
9) SELCK 1.7 STA #1
Alarm 0xFE0E=205 [M]:
- Cause:
This alarm occurs only as a response of the SELFCHECK #1. It
occurs in case the selfcheck #1 has not been passed but none
of the above failure conditions has been detected.
- Remedy:
Only deepen analysis and interpretation of STATUS#1 (see
TESTER menu) may help to finalize the troubleshooting.
10) SELFCHECK #2
Warning 0xFE10=204 [M,S]:
- Cause:
This warning occurs when the SELFCHECKING routine #2 is in
progress and the check result has not been determined yet.
This selfchecking routine carries out an embedded monitoring
of the encoder and of the current in the motor when
commanded to move at a fixed speed of 25Hz. We suggest to
launch SELFCHECK #2 with the steered wheel lifted up. The
goal of this selftest is to check the functionality of encoder and
mechanical components (trasmission, sensor bearings, gears,
pinion). After the gathered data have been processed and an
unexpected result occurred, this warning message will turn in
an alarm information (see below).
- Remedy:
recycle the key to exit the SELFCHECK #2 warning
11) CHECK #2 OK
Warning 0xFE1F=204 [M]:
- Cause:
This alarm occurs only as a response of the SELFCHECK #2. It
occurs in case the selfcheck #2 has passed. Condition for
passing selfcheck #2 are (motor is turning at a fixed speed of
25Hz and the average Encoder increment is expected to be
6.42 in 16msec):
Motor Current lower than 6.5Arms
AND
Encoder Increment higher equal than 4 in 16msec
AND
Encoder Increment lower equal than 8 in 16msec
- Remedy:
Encoder and Transmission work properly.
12) SELCK 2.1 VBATT
Alarm 0xFE11=204 [M]:
- Cause:
This alarm occurs only as a response of the SELFCHECK #2. It
occurs in case the DC Bus (bB and –B posts) is lower
than 29V (for 48V battery) and 19V (for 24V battery).
- Remedy:
It reports a failure on the cable between plus or minus battery
and the controller.
13) SELCK 2.2 ENC LO
Alarm 0xFE12=204 [M]:
- Cause:
This alarm occurs only as a response of the SELFCHECK #2. It
occurs in case the minimum encoder increment in 16msec has
been detected lower than 2 (valley detection) and the average
