16) SL CENTERING
CAN Bus Code = 213
- Cause: This alarm occurs when an automatic centering is requested from
steady state condition. Then the slave uC expects the angle
measured on the steered wheel goes into a window from -20 to
+20 degrees before the traction turns moving. In case the traction
turns moving with a steered wheel outside that window, this alarm
occurs.
- Remedy: It is necessary to replace the controller.
13.1.2 Two Blinks Alarms
1) HIGH CURRENT
CAN Bus Code = 70
- Cause: This alarm occurs if the circuit to limit via hardware the current in
the motor is either always active at key-on or repeatedly active
when the motor is turning.
- Remedy: Check the motor is suited to work with the eps-ac0 (not oversized).
Otherwise it is necessary to replace the controller.
2) POWER FAILURE #1
CAN Bus Code = 73
- Cause: This alarm occurs when the current in the phase W 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 W of
the motor. Otherwise it is necessary to replace the controller.
3) POWER FAILURE #2
CAN Bus Code = 72
- Cause: This alarm occurs when the current in the phase U 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 U of
the motor. Otherwise it is necessary to replace the controller.
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.
