Maintenance 6. Joint #3 (Replacing the Reduction Gear Unit)
S5 Rev.5 131
- After parts have been replaced (motors, reduction gear units, timing belts, etc.), the
Manipulator cannot perform positioning properly because a mismatch exists between the
origin stored in each motor encoder 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 12. Calibration and follow the steps that pertain to the software
you are using to perform the calibration.
- A reduction gear unit consists of the three parts described below. When replacing the
reduction gear unit, be sure to always replace the waveform generator, flexspline, and
circular spline all together as one set.
For the structure details of the reduction gear, refer to Maintenance: 13. Maintenance
Parts List.
