The Mitsubishi MR-J4-70TM-ECT is a servo amplifier rated for 0.75 kW output, powered from a single-phase 200 VAC line, and communicating over EtherCAT.
The 0.75 kW output matches a small servo motor — think indexing tables, pick-and-place axes, or conveyor diverters. Single-phase 200 VAC input simplifies panel wiring where three-phase isn't available, but watch the inrush: a 1-phase supply at 200 VAC means the DC bus charges through a smaller rectifier, so the upstream breaker and cable sizing should follow the drive's input current spec (not the motor's). EtherCAT on board means it drops directly into a motion network without an extra option card — the cycle times are down to 31.25 µs for fast position loops.
