Expert Review
- “The MR-J4-350B delivers rock-solid 3.5 kW power with SSCNET III/H speed. The STO safety reduces external hardware. Its compact frame fits crowded panels. Great for high-duty applications.” – Senior Controls Engineer, Powergear X.
Manager’s Insight
- “For factory upgrades, this Mitsubishi drive cuts wiring time via network control. Built-in dynamic brake and close mounting lower total cost. We recommend it for packaging and CNC retrofits.” – Product Manager, Industrial Automation.
What Devices & Applications Fit Best?
- CNC machines: Milling, lathes, routers – precise axis control.
- Packaging equipment: High-speed indexing, cut-to-length.
- Industrial robots: Pick & place, assembly arms.
- Printing & converting: Tension control, synchronized rolls.
- Material handling: Conveyor drives, stackers.
- Works with Mitsubishi HG series servo motors (medium to high inertia).
Frequently Asked Questions (FAQ)
Q1: Does MR-J4-350B work without a separate dynamic brake resistor?
A: Yes. It has a built-in dynamic brake. For high inertia loads, add an external regenerative resistor.
Q2: Can I use this amplifier with single-phase power only?
A: Main circuit needs 3-phase 200-240V AC. Control circuit works with 1-phase. Use proper 3-phase supply for full 3.5 kW.
Q3: What is the warranty period and shipping speed?
A: 12-month warranty against defects. We ship within 12-24 hours. Couriers: FedEx, UPS, DHL. Tracking provided.
Q4: How to select between MR-J4-350B and other MR-J4 models?
A: Choose MR-J4-350B when you need 3.5 kW power and SSCNET III/H network. For pulse-train control, pick MR-J4-200A. For lower power, check MR-J4-100B.
Q5: Does close mounting affect heat dissipation?
A: Minimal. The design allows side-by-side installation. Keep ambient under 55°C and provide airflow.
Quick Selection Guide
- Confirm motor power: up to 3.5 kW servo motor (Mitsubishi HG series).
- Need network control? SSCNET III/H is high-speed and noise immune.
- Safety required? STO is built-in, no extra relay needed.
- Check voltage: 200-240V AC 3-phase available on site.
- Panel space small? 90mm width allows dense mounting.
