Code: C-1246
Classification: SD: SD-513 abnormality
Cause:
After the gripper motor (M26) starts the home position search operation, the gripper open close home sensor (PS39) does not become active within a specified period of time. Alternatively, a specified period of time has passed since M36 starts the operation. However, the gripper open close sensor (PS40), the gripper angle sensor/1 (PS41), or the gripper angle sensor/2 (PS42) does not become active.
Measures to take when alert occurs:
The main body and the option stop immediately.
Estimated abnormal parts:
- Gripper open close home sensor (PS39)
- Gripper open close sensor (PS40)
- Gripper angle sensor/1 (PS/41)
- Gripper angle sensor/2 (PS/42)
- Gripper motor (M26)
- SD drive board (PCB2)
- SD control board (PCB1)
Press the help key to activate and deactivate the sub power switch (SW2) of the main body.
Note:
- Faulty part isolation allows you to use the machine temporarily.
- The message "Please call service" and "Press [Help] to disengage" are alternately displayed.
- When you press the help key, the message "Please turn on the power again" is displayed.
Solution:
- Check the grip roller drive section, and if there is any abnormality, clean or repair it.
- Check the connector connection and the wiring harness between PCB2 and the motor, PCB1 and the sensor. Then, repair them when there is any abnormality.(Wiring diagram: SD-513 (2/2): 6-B) (Wiring diagram: SD-513 (2/2): 19-O, 20-O).
- Check the connector connection and the wiring harness between PCB2 and PCB1, and if there is any abnormality, repair them.
- Check the I/O drive of the motor and the coupling of the gear, and repair or replace it when there is any abnormality.
- Check I/O and the operation of the sensor, and if there is any abnormality, repair or replace it.
- Replace PS39, PS40, PS41 or PS42.
- Replace M6.
- Replace PCB2.
- Replace PCB1.
