finely adjust the cable length.

Rough guide of temporary fixing: The plate should not move.
Notes for fine adjustment:
- No excess looseness or tension on the cables.
The cables should not be pressed strongly against the arm
edge.
- The X021, X121, BR021, and CN3 connectors should reach
the end face of the Arm #1 when they are pulled out.
The cables should not be too long.
Place a mark on the cables at the sleeve outlet on the base side.
Fix the cable bracket (C1)-A on the near side so that the cable
positions do not change.
