Mitsubishi Electric UK has launched a new next generation of energy efficient Melservo MR-J4 servos amplifiers, complete with associated positioning units. The easy to use motion modules and high-end integrated motion control systems enable machine builders and end users to improve productivity and reduce energy costs.

One touch auto-tune

The series features single, dual and triple axis amplifiers for improved economy, greater energy efficiency and reduced panel space requirements. The servos can all operate with rotary, linear and direct drive motors to simplify the system building process.   Engineering and commissioning time is reduced by a “one touch” auto tune function that matches the machine mechanics to the servo system in a single operation. This function operates in real time and is dynamic, so as the machine conditions change over time, the MR-J4 system tuning automatically adjusts.

Covering the range from 0.1kW to 55kW, MR-J4 servo amplifiers are available in two versions. The MR-J4A provides analogue and pulse train connections and is designed for conventional control systems and for speed, torque and closed-loop position control. The MR-J4B comes with connectivity to Mitsubishi Electric’s SSCNETIII/H high performance servo network, meeting the needs of integrated automation systems where complex multi-axis motion control is required.

SSCNETIII/H control information is delivered over a full duplex 150Mbps fibre optic bus, which simplifies connection and commissioning and permits synchronous coordination of up to 96 axes. Both versions of the amplifier come with built in local I/O for interfacing with signals such as over travel limits and print mark registration.

Life diagnosis function

The MR-J4 amplifiers also include a “life diagnosis function” which monitors the condition of the amplifier at a component level and notifies the user of any degradation in its operation. This feature recognises changes in machine dynamics such as increased vibration and increased motor torque. This aids preventative maintenance and minimises machine downtime.

Outperforms accuracy of other servo by 4 times

The matched servo motors are fitted with 22-bit absolute encoders as standard, corresponding to more than four million pulses per revolution, and outperform the accuracy of other servo motors on the market by a factor of four.  Combined with the processing speed of the MR-J4 servo amplifiers 2.5kHz frequency response and inbuilt vibration suppression filter results in improved machine performance, with minimised positioning times, reduced cycle times and greater throughput.

Features such as STO (Safe Torque Off) and SS1 (Safe Stop 1) are built in as standard, ensuring servo system safety meets EN 61800-5-2. In addition, SS2, SOS, SLS, SBC and SSM safety options are available.
