MITSUBISHI MR-J2S-70B

Product Details MITSUBISHI MR-J2S-70B is a high-performance MELSERVO servo amplifier belonging to the MELSERVO-J2-Super series, designed for SSCNET fieldbus high-speed closed-loop motion control systems. This MELSERVO servo amplifier supports 700W rated power, compatible with 3-phase or single-phase 200VAC input power and pairs perfectly with Mitsubishi HC series servo motors. This MELSERVO servo amplifier adopts sine-wave PWM control, integrated adaptive vibration suppression and machine resonance filter to eliminate mechanical oscillation and improve running smoothness. This MELSERVO servo amplifier supports 131072 pulses/rev high-resolution encoder feedback, delivering ultra-precise positioning performance without frequent home reset after power cycle.

This unit acts as core axis motion drive controller for multi-axis synchronized automation equipment. The axis motion drive controller receives position commands from upper motion controller via SSCNET bus, realizing fast transmission of motion setpoints, operating status and alarm messages. The axis motion drive controller supports position, speed and torque three control modes, and runs automatic gain tuning to simplify on-site commissioning work. The axis motion drive controller integrates comprehensive protective functions including overcurrent, overvoltage, overload, overspeed, undervoltage and encoder fault protection to safeguard the whole servo system. The axis motion drive controller equips status LED indicators and RS232C port, supporting MR Configurator software for parameter editing, real-time monitoring and fault diagnosis.

This reliable legacy servo drive unit is an obsolete original spare part for old production line maintenance. The legacy servo drive unit works stably within 0~55℃ working temperature, resisting electromagnetic interference in complex industrial cabinet environments. The legacy servo drive unit supports dynamic brake function to lock the motor shaft rapidly when emergency stop triggers, improving equipment operation safety. The legacy servo drive unit is widely applied in CNC machine tools, packaging machinery, automated assembly equipment and material handling systems. The legacy servo drive unit can replace damaged original drives to restore multi-axis motion control and minimize unexpected production downtime during equipment overhaul.
