Designed for high-performance multi-axis motion control, the Mitsubishi Electric MR-J4W2-1010B serves as a dual-axis AC servo amplifier operating within the MELSERVO-J4 product line. This unit integrates two independent 1.0 kW drive axes into a single physical housing, significantly reducing panel footprint and simplify cabling. Featuring high-speed SSCNET III/H fiber-optic communication, it provides high-speed synchronous control with real-time feedback. The amplifier is engineered to support rotary, linear, and direct-drive servo motors, adapting to complex motion profiles with integrated vibration suppression and advanced tuning functions.

When migrating from two separate single-axis MR-J4-100B amplifiers to a single MR-J4W2-1010B unit, ensure you are utilizing MR Configurator2 (version 1.20W or higher). The software treats this dual-axis unit under a single physical station address with sub-axis parameter tabs. Check that your PLC network configuration map has assigned consecutive Axis A and Axis B addresses inside the Simple Motion Module or Motion Controller setup.
Since Axis A and Axis B share a single, built-in regenerative resistor, simultaneous deceleration of both high-inertia loads will quickly trigger regenerative overvoltage faults (Fault AL.30 or AL.33). If both axes operate under rapid cyclical start/stop sequences, we strongly advise installing an external regenerative option (such as the MR-RB12) to bypass the internal limits and prevent thermal overload of the integrated bus.
SSCNET III/H fiber-optic cables (CN1A and CN1B) are extremely sensitive to particulate contamination. Use dedicated cleaning fluid and lint-free wipes on the fiber ends before mating. A minute dust particle can degrade signal intensity, resulting in intermittent SSCNET command errors (AL.37 or AL.E4). Observe the minimum bending radius of 25 mm for standard fiber cables; tighter bends can attenuate the optical link signal permanently.
CRITICAL WARNING
Isolate and lock out all 3-phase mains (L1/L2/L3) and control power (L11/L21) circuits before handling wiring. High-voltage charge remains stored in the internal DC bus capacitors after power disconnection. Always wait a minimum of 15 minutes and verify that the voltage across terminals P+ and N- is under 50 VDC using an appropriately rated digital multimeter before initiating maintenance.
