(6) Battery replacement procedure
WARNING
Before replacing a battery, turn off the main circuit power and wait for 15 minutes
or longer until the charge lamp turns off. Then, check the voltage between P+ and
N- with a voltage tester or others. Otherwise, an electric shock may occur. In
addition, when confirming whether the charge lamp is off or not, always confirm it
from the front of the servo amplifier.
CAUTION
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
Ground human body and work bench.
Do not touch the conductive areas, such as connector pins and electrical parts,
directly by hand.
The battery built in MR-BAT6V1BJ cannot be replaced. Do not disassemble the
MR-BAT6V1BJ. Otherwise, it may cause a malfunction.
POINT
To replace the MR-BAT6V1BJ, follow the procedures given in this section to
avoid erasing absolute position data.
Before replacing batteries, check that the new battery is within battery life.
For MR-BAT6V1BJ, the battery can be replaced with the control circuit power supply off.
(a) Battery installation and removal procedure
The battery installation and removal procedure to the servo amplifier are the same as for the MR-
BAT6V1SET battery. Refer to (3) of section 11.8.2.
(b) Preparation for replacing MR-BAT6V1BJ
Prepare a new MR-BAT6V1BJ as follows.
Model Number and use Remark
MR-BAT6V1BJ 1 for replacement Battery within two years from the production date.
(c) Procedures of replacing MR-BAT6V1BJ
Replace the product as follows regardless of on/off of the control circuit power supply. When it is
replaced with other procedures, the absolute position data will be erased.
1) Remove the connector for branch cable connection (black) of the old MR-BAT6V1BJ.

11.8.4 MR-BT6VCASE battery case
POINT
The battery unit consists of an MR-BT6VCASE battery case and five MR-
BAT6V1 batteries.
For the specifications and year and month of manufacture of MR-BAT6V1
battery, refer to section 11.8.5.
MR-BT6VCASE is a case used for connecting and mounting five MR-BAT6V1 batteries. A battery case does
not have any batteries. Please prepare MR-BAT6V1 batteries separately.
(1) The number of connected servo motors
One MR-BT6VCASE holds absolute position data up to eight axes servo motors. For direct drive motors,
up to four axes can be connected. Servo motors and direct drive motors in the incremental system are
included as the axis Nos. Linear servo motors are not counted as the axis Nos. Refer to the following
table for the number of connectable axes of each servo motor.
Servo motor Number of axes
Rotary servo motor 0 1 2 3 4 5 6 7 8
Direct drive motor 4 4 4 4 4 3 2 1 0
