MR-JE-B for Servo Network is now available!

Apply servos to all machines with reliable basic performance and advanced ease-of-use!

Easy To Use

Advanced One-Touch Tuning

Servo gains are adjusted with one-touch ease without a personal computer.

Tolerance against Instantaneous Power Failure

The instantaneous power failure tough drive function and the large capacity capacitor reduce machine downtime.

Absolute Position Detection System

Absolute position detection system can be easily configured with MR-JE-B servo amplifier.

Built-in Positioning Function

MR-JE-A has a built-in positioning function, enabling positioning operation with point table method, etc. Equipped with advanced functions such as simple cam and mark detection.

High Performance


MR-JE-B is compatible with 150 Mbps full duplex high-speed optical network SSCNETIII/H, achieving high-response system.

Fast and Accurate

The dedicated engine enables speed frequency response of 2.0 kHz, shortening the tact time.

High Resolution Encoder

The servo motor is equipped with 131072 pulses/rev (17-bit) high-resolution encoder, achieving high accuracy.

Energy Conservation

The large capacity main circuit capacitor allows the regenerative energy to be used effectively, reducing energy consumption.
