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: VS-6556, VS6577
Tools and Parts needed
- Philips-Head screwdriver (Standard type) or Allen (hex) key (Dust-proof & splash-proof type)
- Encoder backup battery for VS series robots.
- 410611-0070 – Encoder backup battery (3set)
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.
