📌 Expert Review & Manager’s Insight

• 🔍 Expert Review – Senior Drive Engineer:

  “Two axes in one unit. Saves 40% panel space. SSCNET III/H at 0.222ms cycle gives fast response. Built-in 20W regen resistor handles small decelerations well. A smart choice for compact machines.”

• 📈 Manager’s Insight – Automation Product Manager:

  “Lower total cost vs two single drives. Natural cooling means zero fan maintenance. USB setup cuts commissioning time by half. For OEMs building pick-and-place or small conveyors, this is gold.”

🏭 Applications & Suitable Equipment

• Pick-and-place robots: Two independent axes, fast positioning.
• Small CNC routers: X-Y stage control.
• Labeling machines: Precise speed and torque.
• Conveyor belts: Dual motor sync.
• Automatic winding machines: Tension control.
• Test equipment: Load simulation with 2 axes.

❓ FAQ – Professional Answers

• Q1: Can I use MR-J4W2-22B with only one axis active?

  Yes. You can run just one axis. The second axis can stay unused with no problem.

• Q2: What happens if main power is single-phase 220V?

  It works fine. The main circuit accepts 1-phase 200-240V AC. No derating needed for light loads.

• Q3: How to connect to a PC for tuning?

  Use the USB mini-B port. Download MR Configurator2 free from Mitsubishi. Plug and play.

• Q4: (Experience) Drive trips alarm “AL.16” – what to do?

  AL.16 means regenerative overload. Check deceleration ramp. Add external regenerative resistor if stopping heavy load often.

• Q5: Buying guide – warranty and delivery?

  We provide 12 months repair/replace warranty. Ship within 12-24 hours. Carriers: FedEx, UPS, DHL. Fast customs clearance support.

🛒 Selection Tips

• Check your motor’s rated current (≤1.5A per axis).
• For high inertia loads, buy external regenerative resistor (≥40W).
• Use shielded cables for SSCNET III/H communication.
• Keep ambient temperature below 55°C. Natural cooling needs open space.
• Order connector kit separately if lost. Ask us for bundle deals.
