Expert Review – Automation Engineer

The MR-J4-60B offers reliable 600W servo control. The STO safety function simplifies machine safety design. The built‑in dynamic brake stops the motor quickly without extra parts. At only 40mm wide, it saves panel space. Tuning via USB is fast and clear. For single‑axis applications like conveyors or feeders, this amplifier is a smart choice. I recommend it for users who need safety and compactness.

Manager’s Insight – Powergear X Automation

We stock the MR-J4-60B because it meets many customer needs. It works with both 1‑phase and 3‑phase power. The STO function meets global safety rules. The 12‑month warranty and fast 12‑24h shipping via FedEx/UPS/DHL reduce project risks. For OEMs and system integrators, this drive lowers inventory costs. It is a proven, easy‑to‑use servo amplifier.

Applicable Devices & Applications

• CNC machinery – precise spindle or axis control.
• Robotics – single‑joint or gripper control.
• Packaging machines – indexing and cutting.
• Assembly lines – screwdriving or pick‑and‑place.
• Printing equipment – constant tension and speed.
• Lab automation – quiet, compact motion.

Frequently Asked Questions (FAQ)

• What is the maximum output power of MR-J4-60B?
  • 0.6 kW (600 watts). It drives motors up to that rating.
• Does MR-J4-60B support single‑phase power?
  • Yes. It accepts 1‑phase 200‑240 VAC or 3‑phase 200‑240 VAC.
• How do I use the STO safety function?
  • Wire the STO inputs to a safety relay. The amplifier cuts torque safely.
• What is the warranty period and shipping method?
  • 12 months. We ship within 12‑24 hours via FedEx, UPS, or DHL.
• Can I use this amplifier with a non‑Mitsubishi motor?
  • No. It works only with Mitsubishi servo motors (HG series).

Selection Guide & Buying Tips

• Power matching
  • Choose MR-J4-60B for 600W motors. For 400W, see MR-J4-40A.
• Safety requirements
  • If you need STO (safe torque off), pick this model. It meets EN 61800-5-2.
• Axis count
  • This is a single‑axis amplifier. For multi‑axis, use MR-J4-T series.
• Braking needs
  • The built‑in dynamic brake handles emergency stops. No external resistor.
• Panel space
  • 40mm width fits narrow cabinets. Check heat dissipation clearance.

Experienced User Advice

• Noise reduction
  • Keep signal wires away from power cables. Use shielded cables for encoder.
• STO wiring check
  • Test STO function before machine start. Use two independent channels.
• Auto‑tuning tip
  • Run without load first. Then add load and run advanced tuning.
• Parameter backup
  • Save parameters using MR Configurator2. Easy recovery after replacement.
