12.2 Replacing the Battery 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: 14. Calibration to perform the calibration.

Push down the shaft to its lower limit while pressing the brake release switch. Be

s
pressed, the brake
for Joint #3 is released simultaneously.
Be careful of the
shaft while the brake release switch is being pressed because
the
shaft may be lowered by the weight of an end effector
.
