The encoder built in the servomotor stores position data. To prevent the position data from being lost, the encoder backup batteries supply power to the encoder memory.
Periodically replace the encoder backup batteries that are loaded in the robot unit.
This procedure applies to the following robot types: HSR-048, HSR-055, HSR-065
Tools and Parts needed
- Allen (hex) key
- Encoder backup battery for HSR series robots.
- 410679-0010 – Encoder backup battery (2set)
If you are not sure which part number you need or the Robot Arm you own, please stop and contact your DENSO Robotics sales representative.
Make two new backup batteries ready for use. (Always replace two batteries as a pair.)
Turn the controller power OFF.
Remove the cover from the robot unit.
Disconnect the old battery (1st one) from the battery board and then remove it from the holder.
Connect a new battery (1st one) to the battery board from which you have disconnected the old one in Step 4, and then load it into the holder.
Disconnect the remaining old battery (2nd one) from the battery board and then remove it from the holder.
Connect a new battery (2nd one) to the battery board from which you have disconnected the old one in Step 6, and then load it into the holder.
Install the cover to the robot unit.
