A new cable needs to be
prepared. Refer to (3) of this
section for details.
Analog monitors (MO1 and
CN3
MO2) are not supported. When
using MO1 and MO2, please
consider replacing the servo
amplifier with two MR-J4 single-
axis servo amplifiers.
Replace the existing connectors
CNP1
with the ones supplied with the
CNP2
servo amplifier.
CNP3A
CNP3B
A new battery needs to be
prepared.

For details, refer to "MR-J4W2-
_B Servo Amplifier Instruction
Manual".
When not using the STO in MR-
J4W2, attach the short-circuit
CN8
connector supplied with the
servo amplifier to CN8.
