The MR-J4 series is the latest offering in the company's line of servo motors, servo amplifiers and motion controllers. According to the company, the new product offers frequency of 2500Hz, reducing settling times to less than two milliseconds to maximize machine performance and throughput for machine builders and end-users. A modular architecture provides a redundant two-channel STO input (Safe Torque Off) as standard on all MR-J4 amplifiers, and an optional module to provide SS1 (Safe Stop) input in line with EN61800-5-2. The system configuration also supports SIL2 (EN62061) and PLd (EN13849-1). For more advanced systems needing a high level of safety support for SS2, SOS, SLS, SBC and SSM, Mitsubishi Electric's MR-J4B employs amplifiers and motion controllers with safety modules. This flexibility allows users to reduce costs by "tuning" their system configuration to meet only the needed safety requirements for the target applications. In addition to the MR-J4A (analog/pulse train) and MR-J4B (SSCNET III/H motion network) models, the MR-J4 series includes two additional versions for two- and three-axis operation amplifiers. A more compact and efficient solution, this approach not only saves the machine manufacturer money in terms of energy costs and reducing CO2 emissions, but also saves on cabinet and panel space. According to the manufacturer, the next generation MR-J4 servo family also delivers cost savings with bus speeds three times faster via SSCNET III/H (Serial Network from Servo to Motion)*. And MR-J4 servos need fewer connections and less wiring and reduced energy consumption due to an increase of re-usable, regenerated energy when using the three axis model.
