Servo Amplifier Correspondence
The applicable servo system network is changed from SSCNET to SSCNET III or SSCNET III/H. Use
servo amplifiers compatible with SSCNET III or SSCNET III/H. Select a servo motor that can be connected
with an SSCNET III or SSCNET III/H-compatible servo amplifier.

For the communication with servo amplifiers, "SSCNET III" or "SSCNET III/H" must be set for each system in
the SSCNET setting of the system setting.
When "SSCNET III/H" is set, MR-J4(W)-□B can be used. When "SSCNET III" is set, MR-J3(W)-□B can be
used.
When MR-J4(W) (MR-J3 compatibility mode compatible product) is connected to the system where "SSCNET
III" is set, the servo amplifier operates in the MR-J3 compatibility mode (SSCNET III). However, if the
MR-J4(W) that was once connected to "SSCNET III/H" is connected to "SSCNET III", an alarm may occur. For
details, refer to MR-J4 SERVO AMPLIFIER INSTRUCTION MANUAL.
