Step by Step Guide

Step 1

Prepare a new set of 3 backup batteries for replacement.

Note: Be sure to replace all of three batteries with new ones at one time.

Step 2

Turn the controller power OFF.

Step 3

Remove the hexagon socket-head bolts (Allen bolts) from the battery support plate.

<Standard type (VM-6083, VM-60B1)>
<Dust- & splash-proof type (VM-6083-W, VM-60B1-W)>

Step 4

Pull out the battery support plate from the robot unit.

<Standard type ( VM-6083 ,VM-60B1)>
< Dust- & splash-proof type (VM-6083-W, VM-60B1-W) >

Step 5

Remove the dummy connector cap from the battery board.

Step 6

Connect a new battery (1st one) to the pin from which you have disconnected the dummy connector cap in Step 5.

NOTE:
Do not disconnect old backup batteries before connecting a new one to the pin from which the dummy connector cap is removed. If you do so, the encoder positional data may be lost.

Step 7

Disconnect the old backup battery that is left next to the new battery connected in Step 6, and then connect a new battery (2nd one).

Step 8

Disconnect the old backup battery that is left next to the new battery connected in Step 7, and then connect a new battery (3rd one).

Note:
Be sure to replace all of three batteries with new ones at one time. Otherwise, the battery service life will become short.

Step 9

Remove the last old battery and connect the dummy connector cap disconnected in Step 5.

Step 10

Secure the battery support plate to the connector plate.
Tightening torque: 1.6 ±0.3 Nm
