Servo Amplifiers MR-J3

The new MR-J3 generation of servo drives delivers state-of-the-art technology and simple operation in a very compact package.

Mitsubishi Electric Servo Amplifiers MR-J3

Features

  • 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
  • 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 two 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.

    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.
