5.3.1 Battery replacement procedure
Model: MR-BAT6V1SET, MR-BAT6V1BJ, MR-BT6VCASE
WARNING

control circuit power supply turned on will cause [AL.9F.1 low battery] but will not erase the absolute position
data.
Refer to the Instruction Manual for the procedure for mounting the battery on the servo amplifier.
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.
The internal circuits of the servo amplifier may be damaged by static electricity.
Always take the following precautions.
Ground your body and the work bench.
Do not touch the conductive areas, such as connector pins and electrical parts,
directly by hand.
The built-in battery for the MR-BAT6V1BJ battery for junction battery cable cannot
be replaced. Therefore, do not disassemble the MR-BAT6V1BJ battery for
junction battery cable. Doing so may cause a malfunction.
