Servo Amplifiers MR-J3
AC Servo Systems
Servo and Motion system products provide solutions for applications as simple as a single axis point-to-point system through to fully synchronised 96 axis systems.
Servo Amplifiers
With their 32bit RISC processors, these advanced servo amplifiers include features such as Real Time Adaptive Tuning and Zero-speed mocrovibration suppression. Real Time Adaptive Tuning is unique to Mitsubishi’s servo amplifiers. Not only does it automatically tune to match the load, it also has the capability to adjust these values even if the load changes. This means that it is easy and fast to set-up for optimum respose without compromising performance.
Servo Motors
All servo motors in the Mitsubishi range use rare earth magnets and concentrated winding techniques to keep the inertia of the rotor extremely low. They also incorporate serial encoders for high resolution that is much less susceptible to noise, thus ensuring integrity in positioning. In addition, all motors are rated for up to 300 percent overload.
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.
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.
