11.2 Replacing the Resolver Board
After battery board and parts have been replaced (motors, reduction gear units, brakes,
timing belts, ball screw spline unit, etc.), the manipulator cannot operate properly because
a mismatch exists between the origin stored in each motor and its corresponding origin
stored in the controller.
After replacing the parts, it is necessary to match these origins.
The process of aligning the two origins is called “Calibration”.
Refer to Maintenance: 13. Calibration to execute the calibration.
