It is the motion-axis amplifier for a MELSERVO-J5 system, receiving position/velocity commands from a motion controller over the high-speed fiber-optic SSCNETIII/H network and driving a compatible servo motor with feedback. ## What SSCNETIII/H means for integration SSCNETIII/H is Mitsubishi's high-speed synchronous motion network, running at 150 Mbps over fiber-optic cable. It carries position data, status, and parameter uploads between the motion controller and up to 64 axes in a daisy-chain or ring topology. The MR-J5-70B is a node on that network — it does not contain a motion controller itself, so it requires a compatible SSCNETIII/H master (e.g., a Mitsubishi iQ-R or iQ-F PLC with motion module). The drive's power stage is rated for 70B-class output (the '70' in the order code typically corresponds to a 7 kW servo motor, though the exact motor match should be verified from the motor nameplate). The 'B' suffix indicates the standard model with built-in dynamic brake and regenerative resistor.","metaTitle":"Mitsubishi MR-J5-70B MELSERVO Servo Drive, SSCNETIII/H","metaDescription":"Mitsubishi MELSERVO MR-J5-70B servo drive with SSCNETIII/H interface.
