error
Main causes include:
1. Discharged batteries.
2. Defective encoder battery board (1FG/1HG board).
3. Defective encoder.
4. Short in the harness from the encoder battery backup board to the encoder.
5. Short in the harness or defective encoder causing increased battery discharge.
6. Battery alarm signal line from the 1FG/1HG board is disconnected.
7. Defective servo board (1KB board).
⇒
Replace the battery. There is a possibility that internal encoder data may be lost.
Check the robot zeroing.
⇒
Check each harness for short circuit.
⇒
Replace the encoder, the 1KB servo board, or the 1FG/1HG encoder battery backup
board, if necessary.
