The new MR-J3 generation of servo drives delivers state-of-the-art technology and simple operation in a very compact package. New functions like the advanced vibration suppression system and the further improved real-time autotuning ensure maximum precision, very short positioning times and simple installation. The new amplifiers are a full 40% slimmer than those of the MR-J2 Super series..

The MR-J3 series is available in three versions: The MR-J3-A models are suitable for drive systems with conventional control and are designed for regulating speed, torque and position control tasks. The MR-J3-B models are specified for complex, multi-axis movement sequences and for use in networked automation systems. A servo amplifier with built-in positioning ( MR-J3-T) is also available.

The units configure themselves by Plug & Play for Mitsubishi Electric' s motion control and positioning control systems, to which they are connected via the high-speed optical SSCNET III network, which has a cycle period of just 0.44 milliseconds. The MR-J3 is currently available with outputs from 50W to 7kW. Units with higher outputs are being added to the range at regular intervals.

Highlights:

* High-speed controllers for ultra-short positioning times; average speed frequency response 900Hz
* High-resolution encoders for maximum speed constancy ( 18 bits 262, 144 P/ rev)
* Advanced vibration suppression for outstanding adaptation to machine requirements
* Autotuning for extremely fast setup and installation
* Optimum cost/ benefit ratio
* Absolute position encoder included as standard equipment
* Minimum wiring overheads thanks to Plug & Play configuration and automatic motor identification
* Supports global standards
