4) POWER FAILURE #3
CAN Bus Code = 71
- Cause:
This alarm occurs when the current in the phase V of the motor is
zero and the motor is commanded for moving.
- Remedy:
Check the power fuse is OK. Check the battery positive arrives to
the controller. Check the continuity of the wire in the phase V of
the motor. Otherwise it is necessary to replace the controller.
5) LOGIC FAILURE #1
CAN Bus Code = 19
- Cause:
This alarm occurs when the real voltage between phases W and U
of the motor is different from the desired.
- Remedy:
It is necessary to replace the controller.
6) LOGIC FAILURE #2
CAN Bus Code = 18
- Cause:
This alarm occurs when the real voltage between phases W and V
of the motor is different from the desired.
- Remedy:
It is necessary to replace the controller.
7) MAIN CONT. OPEN
CAN Bus Code = 48
- Cause:
This alarm occurs only when the setting CAN BUS is PRESENT.
Then the eps-ac0 waits for a via CAN information that the traction
controller has closed the main contactor. If this information lacks
more than about 1.5 secs, this alarm occurs.
- Remedy:
Find, on the traction controller, the reason for keeping the main
contactor open.
8) CAN BUS KO
CAN Bus Code = 247
- Cause:
This alarm occurs only when the setting CAN BUS is PRESENT.
Then the eps-ac0 must receive the event messages from the
traction controller. If these messages lack more than about 1 sec,
this alarm occurs.
- Remedy:
Check the CAN Bus communication system and analyse the
frames from the traction controller to the steer controllers.
9) MOTOR LOCKED
CAN Bus Code = 220
- Cause:
This alarm occurs if the current in the steering motor stays close to
the maximum current longer than 1 sec.
- Remedy:
Search for a mechanical problem locking the motor. To make
easier the fault catching, set DEBUG OUTPUT to level 11 (see
12.4.6.4).
14.1.3 Three Blinks Alarms
1) D LINE SENSOR KO
CAN Bus Code = 243
- Cause:
This alarm occurs when the mean voltage on the Direct line of the
stepper motor (connection CNA#9) is not null: the voltage on every
stepper motor line is a sine wave with null mean voltage.
- Remedy:
Check the continuity of the stepper motor connections. In particular
the resistance between CNA#9 and the minus battery (with the
