1.1 Summary

The Mitsubishi Electric general-purpose AC servo MELSERVO-JE series have limited functions with keeping

high performance based on MELSERVO-J4 series.

The servo amplifier has position, speed, and torque control modes. In the position control mode, the

maximum pulse train of 4 Mpulses/s is supported. Further, it can perform operation with the control modes

switched, e.g. position/speed control, speed/torque control and torque/position control. Hence, it is

applicable to a wide range of fields, not only precision positioning and smooth speed control of machine tools

and general industrial machines but also line control and tension control.

The servo amplifier supports profile position/velocity/torque mode that drive motors with communication from

the controller. By specifying target position, target speed, acceleration time constant, and deceleration time

constant, a position command is created in the servo amplifier and the motor will be driven.

With built-in positioning function, the positioning operation can be performed by using point table method or

indexer method. Suitable for assembling a simple positioning system or for simplifying the system.

Drive motor, monitor, and parameter setting can be done with CC-Link IE field network Basic, SLMP,

Modbus/TCP and various Modbus RTU open networks by installing the general-purpose Ethernet connector

and RS-485 communication connector in each port.

With one-touch tuning and real-time auto tuning, you can automatically adjust the servo gains according to

the machine.

The tough drive function, drive recorder function, and preventive maintenance support function strongly

support machine maintenance.

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.

The MELSERVO-JE series servo motor equipped with an absolute position encoder whose resolution is

131072 pulses/rev will enable a high-accuracy positioning.
