HSR Series Encoder Battery Replacement

Modified on Wed, 16 Oct at 4:54 PM

Please read our Legal Disclaimer before executing any steps on this article. 


Overview

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)
NOTE:
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.

Step-by-Step Guide


Step 1

Make two new backup batteries ready for use. (Always replace two batteries as a pair.)  


Step 2

Turn the controller power OFF. 



Step 3

Remove the cover from the robot unit.
Four hex. Socket-head bolts (M3x8)


Step 4

Disconnect the old battery (1st one) from the battery board and then remove it from the holder. 


Step 5

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.  


NOTE:
Do not disconnect both of the current batteries at the same time. Doing so will lose the encoder positional data.

Step 6

Disconnect the remaining old battery (2nd one) from the battery board and then remove it from the holder. 


Step 7

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.


NOTE:
Be sure to replace both of the two batteries with new ones at one time. Otherwise, the battery service life will become short.

Step 8

 Install the cover to the robot unit.
 Hex. Socket-head bolt (M3x8): 1.6±0.3 N•m
