overloaded).
17) SELCK 2.6 I > 10A
Alarm 0xFE16=204 [M]:
- Cause:
This alarm occurs only as a response of the SELFCHECK #2. It
occurs in case the average encoder increment in 16msec has
been detected very close to the expected (higher than 6) and
the average current in the motor has been detected higher than
10Arms (too high for a lifted up steered wheel).
Note: at fixed 25Hz the average encoder increment is expected
to be 6.42 in 16msec.
- Remedy:
This situation is physiological when the steered wheel is on a
flat surface (we have measured 12Arms to steer an unloaded
truck @ Tamb=25°C). This situation must be investigated in
case it occurs with the steered wheel lifted-up (only very low
Tamb could physiological affect significantly the friction in the
transmission).
18) SELCK 2.7 POWER
Alarm 0xFE17=204 [M]:
- Cause:
This alarm occurs only as a response of the SELFCHECK #2. It
occurs in case the current in the motor does not reach the
commanded value for turning the motor at 25Hz.
- Remedy:
it reports a problem in the power actuator of the system
(including 3phase power bridge and motor). A SELFCHECK #1
test may help to clarify if the problem is in the motor or in the
controller.
19) SELCK 2.8 STA #2
Alarm 0xFE1E=204 [M]:
- Cause:
This alarm occurs only as a response of the SELFCHECK #2. It
occurs in case the selfcheck #2 has not been passed but none
of the above failure conditions has been detected.
- Remedy:
Only deepen analysis and interpretation of STATUS#2 (see
TESTER menu) may help to finalize the troubleshooting
