5.3 MR-J4-Series Battery

5.3.1 Battery replacement procedure

Model: MR-BAT6V1SET, MR-BAT6V1BJ, MR-BT6VCASE
WARNING
CAUTION
Replace the old battery with only the control circuit power supply turned on. Replacing a battery with the
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 (when 30 kW or more is used, 20 minutes or more) 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.
POINT
When using the BAT6V1SET battery and the MR-BT6VCASE battery case are
used
Replacing a battery with the control circuit power supply turned off will erase the
absolute position data.
When using the MR-BAT6V1BJ battery for junction battery cable
In order to prevent the absolute position data from being erased, replace the
MR-BAT6V1BJ battery for junction battery cable according to the procedure
described in the Instruction Manual.
Verify that the battery for replacement is within its service life.
POINT
Refer to the Instruction Manual for battery transportation and the new EU
Directive on batteries.
