C4 Maintenance 12. Replacing the Battery Unit
152 C Series Maintenance Manual Rev.2
12.2 Replacing the Battery Board
After parts have been replaced (motors, reduction gear units, brakes, timing belts, etc.), the
Manipulator cannot perform positioning properly because a gap exists between the origin
stored in each motor encoder and its corresponding origin stored in the Controller.
Therefore, it is necessary to match these origins after replacing the parts.
The process of aligning the two origins is called “Calibration”.
Refer to
C4 Maintenance 16. Calibration and perform the calibration after the parts
replacement.
