3. COMMON POINTS TO NOTE
3.1 Points to Note When Replacing a Battery
POINT
The MR-BAT and A6BAT battery for MR-J2S and the MR-J2M-BT battery unit
for MR-J2M cannot be used due to different battery voltage specifications.
The battery replacement procedures for MR-J2S/J2M and for MR-J4 are
different.
(The HC/HA motor has a super capacitor condenser.)
When replacing the battery for MR-J4, observe the following points and
procedures.
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.
POINT
Replacing battery with the control circuit power off will erase the absolute
position data.
Verify that the battery for replacement is within its service life.
POINT
Replace the old battery with only the control circuit power supply turned on.
Replacing battery with the control circuit power on will not erase the absolute
position data.
