Expert Review – Motion Control Specialist
The MR-J4W2-1010B cuts panel space by half. One drive runs two motors. The built‑in dynamic and regenerative brakes handle deceleration without extra parts. SSCNET III/H offers fast, real‑time control. At 1kW per axis, it suits many factory machines. For OEMs building multi‑axis systems, this drive lowers cost and wiring time. Highly recommended for pick‑and‑place or small CNC.
Manager’s Insight – Powergear X Automation
We see strong demand for the MR-J4W2-1010B. It simplifies dual‑axis builds. The 12‑month warranty and 12‑24h shipping via FedEx/UPS/DHL give our customers confidence. The regenerative brake saves energy. IP20 protection keeps dust out. For packaging, labeling, or assembly lines, this is a smart, compact choice.
Applicable Devices & Applications
- Pick‑and‑place machines – control X and Z axes together.
- Small CNC routers – drive two axes with one unit.
- Packaging equipment – feeder and cutter axes.
- Labeling machines – conveyor and label head.
- Assembly robots – dual‑arm or dual‑station.
- Printing presses – two synchronized rollers.
Frequently Asked Questions (FAQ)
- How many motors can MR-J4W2-1010B control?
- Two motors. Each axis provides 1kW output.
- Does it work with 1‑phase power?
- Yes. Use 1‑phase 200‑230 VAC or 3‑phase.
- What is SSCNET III/H?
- A high‑speed motion network from Mitsubishi.
- Are both brakes built‑in?
- Yes. Dynamic brake and regenerative brake are inside.
- What warranty and shipping do you offer?
- 12 months. We ship within 12‑24 hours via FedEx, UPS, or DHL.
Selection Guide & Buying Tips
- Axis count
- Need two axes? This unit saves space and cost vs two single drives.
- Power per axis
- Each axis max 1kW. For higher power, see MR-J4W2-2020B.
- Braking needs
- Built‑in regenerative brake handles most deceleration. No external resistor.
- Communication
- Must use SSCNET III/H. Not for pulse‑train or RS‑422.
- Cooling
- Forced ventilation required. Keep fans clean.
Experienced User Advice
- Wiring order
- Connect SSCNET III/H cables in a daisy chain. Terminate at last drive.
- Brake test
- Test dynamic brake with emergency stop. It stops motors fast.
- Parameter backup
- Save parameters for both axes separately using MR Configurator2.
- Heat management
- Leave 100mm above fan outlet for hot air.
