The Mitsubishi MR-JE-10B is a digital AC servo amplifier rated for a 100 W servo motor. It accepts a 3-phase or 1-phase 200 V AC supply (permissible range 170 V AC to 264 V AC at ±5% frequency tolerance) and delivers a 3-phase 170 V AC output at 1.1 A — the figure that governs actual motor torque, not the 0.9 A input draw. The built-in dynamic brake holds the load on a power-loss or E-stop event, which matters for vertical-axis applications where a coasting drop would crash tooling or product.
Control interface and feedback loop
Communication runs on SSCNET III/H at a cycle of 0.444 ms or 0.888 ms, settable to match the motion controller's bus timing. The control method is sine-wave PWM with current control — standard for this class of drive, giving smooth torque down to near-zero speed without cogging. The 24 V DC ± 10% interface supply (0.3 A capacity) powers the control logic and encoder feedback; pull that from a separate PELV source, not the motor power bus, to keep noise off the position loop.
Listed to UL 508C (power conversion equipment) and CE-marked to LVD EN 61800-5-1 and EMC EN 61800-3 — the EMC standard for adjustable-speed drives. The lifecycle stage is current production, so this is a standard-catalog order, not a last-time-buy scavenger hunt.
