POINT
Refer to "Servo Amplifier Instruction Manual" for the replacement procedure of
the battery.
Disconnecting the encoder cable will erase the absolute position data. After
disconnecting the encoder cable, always execute home position setting and then
positioning operation.
The battery MR-J3BAT for MR-J3 series is unavailable because the voltage
specification of the battery differs from that for MR-J4 series.
The battery MR-BAT for MR-J3W series is unavailable because the voltage
specification of the battery differs from that for MR-J4 series.
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.
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.
If [AL. 25 Absolute position erased] or [AL. E3 Absolute position counter warning]
has occurred, always perform home position setting again. Otherwise, it may
cause an unexpected operation.
