1 FUNCTIONS AND CONFIGURATION
1.1 Summary
The Mitsubishi Electric general-purpose AC servo MELSERVO-J4 series have further higher performance and higher
functions compared to the previous MELSERVO-J3 series.
MR-J4-_GF_ servo amplifier can be connected to controllers, such as a simple motion module on CC-Link IE Field Network.
CC-Link IE Field Network is an open network using Ethernet (1000BASE-T), allowing high-speed and large-capacity
communication. A communication speed of 1 Gbps achieves high-speed control of field devices and high-speed
communication between facilities, thus shortening operating cycle.
MELSERVO-J4 series compatible rotary servo motor is equipped with 22-bit (4194304 pulses/rev) high-resolution 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-_GF_ 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 easily 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.
MR-J4-_GF_ servo amplifier supports the Safe Torque Off (STO) function. By combining with optional MR-J3-D05, the servo
amplifier supports Safe stop 1 (SS1) function.
The 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 the MELSERVO-J4 series, servo amplifiers with the CN2L connector are also available as MR-J4-_GF_-RJ.
By using the CN2L connector, an A/B/Z-phase differential output type 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-_GF_ and MR-J4-_GF_-RJ servo amplifiers.

Page 30 Servo amplifier standard specifications *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-_GF-RJ servo amplifier. MR-J4-_GF 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 the following.
Page 280 TROUBLESHOOTING *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.
