1. To prevent electric shock, note the following
WARNING
Before wiring and inspections, turn off the power and wait for 15 minutes or more until the charge lamp
turns off. Then, confirm that the voltage between P+ and N- is safe with a voltage tester and 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.
Ground the servo amplifier and servo motor securely.
Any person who is involved in wiring and inspection should be fully competent to do the work.
Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, it
may cause an electric shock.
Do not operate switches with wet hands. Otherwise, it may cause an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric
shock.
During power-on or operation, do not open the front cover of the servo amplifier. Otherwise, it may cause
an electric shock.
Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging
area are exposed and you may get an electric shock.
Except for wiring and periodic inspection, do not remove the front cover of the servo amplifier even if the
power is off. The servo amplifier is charged and you may get an electric shock.
To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo
amplifier to the protective earth (PE) of the cabinet.
To avoid an electric shock, insulate the connections of the power supply terminals.
2. To prevent fire, note the following
CAUTION
Install the servo amplifier, servo motor, and regenerative resistor on incombustible material. Installing
them directly or close to combustibles will lead to smoke or a fire.
Always connect a magnetic contactor between the power supply and the main circuit power supply (L1,
L2, and L3) of the servo amplifier, in order to configure a circuit that shuts down the power supply on the
side of the servo amplifier’s power supply. If a magnetic contactor is not connected, continuous flow of a
large current may cause smoke or a fire when the servo amplifier malfunctions.
Always connect a molded-case circuit breaker, or a fuse to each servo amplifier between the power
supply and the main circuit power supply (L1, L2, and L3) of the servo amplifier, in order to configure a
circuit that shuts down the power supply on the side of the servo amplifier’s power supply. If a moldedcase circuit breaker or fuse is not connected, continuous flow of a large current may cause smoke or a
fire when the servo amplifier malfunctions.
When using the regenerative resistor, switch power off with the alarm signal. Otherwise, a regenerative
transistor malfunction or the like may overheat the regenerative resistor, causing smoke or a fire.
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the servo amplifier and servo motor.
3. To prevent injury, note the following
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal. Otherwise, a
burst, damage, etc. may occur.

1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Summary
The Mitsubishi MELSERVO-J4 series general-purpose AC servo has further higher performance and higher
functions compared to the previous MELSERVO-J3 series.
MR-J4-_B_ servo amplifier is connected to controllers, including a servo system controller, on the highspeed synchronous network SSCNET III/H. The servo amplifier directly receives a command from a
controller to drive a servo motor.
MELSERVO-J4 series compatible rotary servo motor is equipped with 22-bit (4194304 pulses/rev) highresolution absolute encoder. In addition, speed frequency response is increased to 2.5 kHz. Thus, faster and
more accurate control is enabled as compared to MELSERVO-J3 series.
MR-J4-_B_ servo amplifier operates MELSERVO-J4 series compatible rotary servo motors, linear servo
motors, and direct drive motors as standard.
With one-touch tuning and real-time auto tuning, you can automatically adjust the servo gains according to
the machine.
The tough drive function and the drive recorder function, which are well-received in the MELSERVO-JN
series, have been improved. The MR-J4 servo amplifier supports the improved functions. Additionally, the
preventive maintenance support function detects an error in the machine parts. This function provides strong
support for the machine maintenance and inspection.
SSCNET III/H achieves high-speed communication of 150 Mbps full duplex with high noise immunity due to
the SSCNET III optical cables. Large amounts of data are exchanged in real-time between the controller and
the servo amplifier. Servo monitor information is stored in the upper information system and is used for
control.
On the SSCNET III/H network, the stations are connected with a maximum distance of 100 m between them.
This allows you to create a large system.
The MR-J4-_B_ servo amplifier supports the Safe Torque Off (STO) function. When the MR-J4W_-B servo
amplifier is connected to a SSCNET III/H-compatible servo system controller, in addition to the STO function,
the servo amplifier also supports the Safe Stop 1 (SS1), Safe Stop 2 (SS2), Safe Operating Stop (SOS),
Safely-Limited Speed (SLS), Safe Brake Control (SBC), and Safe Speed Monitor (SSM) functions.
The MR-J4W_-B servo amplifier has a USB communication interface. Therefore, you can connect the servo
amplifier to the personal computer with MR Configurator2 installed to perform the parameter setting, test
operation, gain adjustment, and others.
In MELSERVO-J4 series, servo amplifiers with CN2L connector is also available as MR-J4-_B_-RJ. By using
CN2L connector, an A/B/Z-phase differential output method external encoder can be connected to the servo
amplifier. In a fully closed loop system, a four-wire type external encoder is connectable as well. The
following table indicates the communication method of the external encoder compatible with MR-J4-_B_ and
MR-J4-_B_-RJ servo amplifiers.

P2 of MR-J3 servo amplifiers.
3. This is for MR-J4-_B-RJ servo amplifier. MR-J4-_B servo amplifier does not have CN2L connector.
4. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does
not stop immediately but coasts at an alarm occurrence for which the servo motor does not decelerate to stop. Ensure the
safety in the entire equipment. For alarms for which the servo motor does not decelerate to stop, refer to chapter 8.
5. The power factor improving AC reactor can also be used. In this case, the power factor improving DC reactor cannot be used.
When not using the power factor improving DC reactor, short P3 and P4.
6. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake
interlock) in [Pr. PD07] to [Pr. PD09]. Failure to do so will cause the servo amplifier to become servo-off when an
instantaneous power failure occurs.

1. FUNCTIONS AND CONFIGURATION
Note 1. Refer to section 1.3 for the power supply specification.
2. MR-J4 servo amplifier has P3 and P4 in the upstream of the inrush current suppression circuit. They are different from P1 and
P2 of MR-J3 servo amplifiers.
3. This is for MR-J4-_B4-RJ servo amplifier. MR-J4-_B4 servo amplifier does not have CN2L connector.
4. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does
not stop immediately but coasts at an alarm occurrence for which the servo motor does not decelerate to stop. Ensure the
safety in the entire equipment. For alarms for which the servo motor does not decelerate to stop, refer to chapter 8.
5. The power factor improving AC reactor can also be used. In this case, the power factor improving DC reactor cannot be used.
When not using the power factor improving DC reactor, short P3 and P4.
6. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake
interlock) in [Pr. PD07] to [Pr. PD09]. Failure to do so will cause the servo amplifier to become servo-off when an
instantaneous power failure occurs.
