Charge lamp
Illuminates when the main circuit power supply is
ON. Do not plug/unplug power lines when this
lamp is ON.
Control signal (for operation panel)
Connected to the PLC’s I/O port or the
machine’s operation panel.
CN3 for RS-232C communication (option)
Connect the unit to user’s personal
computer to perform monitoring, batch
parameter entry and saving, graph display,
and test operation. Dedicated cable and
MR Configurator (setup software) are
available also.
(Note 2)
Optional regeneration unit (option)
Install this unit in situations involving fre-
quent regeneration and large load iner-
tia moments. Connect this unit referring
to “Standard Wiring Diagram”.
Notes: 1. If a 1-phase power supply (230VAC) is used, please connect it to terminals L1 and L2. Nothing should be connected to L3.
2. RS-232C and RS-422 are mutually-exclusive features. RS-422 communication is possible with parameter switching.
The RS-422 communication cable can be made by using the optional CN1 connector (MR-J2CN1).
3. The connections with the peripheral devices shown above apply for the MR-J2S-350A or smaller. Connect the MR-J2S-500A or larger and the MR-J2S-60A4 (400V type) or larger as
shown in the standard connection diagram.

Junction terminal block (option)
All signals can be recieved
easily at this terminal block
without a connection to
CN1A or CN1B.

Battery compartment (option)
Display panel
Setting section
A battery (MR-BAT) is installed in the holder when
your servo system is an absolute system. Not re-
quired when your servo system is an incremental
system.
Displays monitoring data, parameters,
and alarms.
Parameter settings and monitoring
etc. are executed with push buttons.
