The Mitsubishi MR-J4-10B1-RJ is a servo amplifier delivering 0.1 kW rated output, designed for single-phase 100-120 VAC supply lines. It communicates over the SSCNET III/H high-speed motion network and supports full closed-loop control for position and velocity feedback from a separate encoder.
What the ratings mean for fit
The 0.1 kW output (100 W) matches small-axis servo applications — indexing tables, pick-and-place Z-axes, or conveyor diverters under 0.5 N·m continuous torque. The single-phase 100-120 VAC input means it plugs into standard North American or Japanese 115 V branch circuits without a step-down transformer; no three-phase power is required at the cabinet. SSCNET III/H is Mitsubishi's proprietary high-speed synchronous network, running at 150 Mbps over a dedicated fiber-optic ring. It carries position commands, feedback, and parameter data between the motion controller and up to 256 axes per network. The 'full closed-loop control' designation means the amplifier accepts feedback from both the motor encoder and an external linear scale or rotary encoder — essential for applications demanding backlash compensation or sub-micron positioning.
