A personal computer is connected by
using the RS-422/RS-232C converter.

RS-422 communication (CN3)
The speed or torque’s
analog signal is
output. (2ch)

Optional
regeneration unit
(option)
Install this unit in situations
involving frequent regener-
ation and large load inertia
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. When a personal computer is connected with the RS-422/RS-232C converter cable (refer to “Introductory Parts” in this catalog), some functions of the MR Configurator (setup software)
may be limited.
3. This example is the case that the cable from the motor is led out in the opposite direction of the motor shaft. An option cable is also available for leading the cable out in the direction of
motor shaft. Refer to the section “Options ● Cables and Connectors” in this catalog.
4. Always disconnect the connection across P1-P2 when using the FR-BEL.
5. Always disconnect the connection across P-D when connecting the optional regeneration unit externally.
Servo motor HF-
(Above picture is HF-KP13.)
Junction terminal block (option)
All signals can be recieved easily at
this terminal block without a connection
to CN1.
Positioning controllers
The MR-J3-A can be connected to a
Mitsubishi controller or any pulse train
output controller.
Battery (option)
Display panel
Setting section
A battery (MR-J3BAT) is installed
in the holder when your servo
system is an absolute system.
Not required when your servo
system is an incremental sys-
tem. Leave the control circuit
power supply ON while replac-
ing the battery.
Displays monitoring data, parameters,
and alarms.
Parameter settings and monitoring
etc. are executed with push buttons.
Servo amplifier
MR-J3- A
(Note 4)
(Note 5)
Used to protect the power
supply line.
Circuit breaker
(NFB)
Power supply
3-phase 200-230VAC
or
1-phase 230VAC
(Note 1)
Used to turn off the
servo amplifier’s power
when an alarm has been
triggered.

reactor (FR-BEL)
Charge lamp
Illuminates when the
main circuit power supply
is ON. Do not plug/un-
plug 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.
USB communication (CN5) (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.
