Mitsubishi MR-J4W2-1010B Dual Axis Servo Drive 1kW

MR-J4W2-1010B Mitsubishi Dual-Axis Servo Drive

Product Introduction

The MR-J4W2-1010B belongs to the MELSERVO MR-J4 family. This servo amplifier controls two axes simultaneously. You save space and cost compared to two single-axis drives. It works well for packaging, pick-and-place, and general automation.

This drive accepts either single-phase or three-phase input. The rated supply voltage ranges from 200 to 230 volts AC. Additionally, it tolerates voltage fluctuations from 170 to 264 volts AC. Such flexibility makes the MR-J4W2-1010B suitable for different factory power conditions.

The command interface uses SSCNET III/H. This protocol enables high-speed, real-time communication with Mitsubishi controllers. You get precise motion control with minimal wiring. Therefore, the MR-J4W2-1010B is a smart choice for multi-axis machines.

Key Technical Specifications

The MR-J4W2-1010B offers robust performance for demanding applications. Below are its main technical features.

• Number of Axes: 2 axes

• Input Phase: 1-phase or 3-phase

• Command Interface: SSCNET III/H

• Output Power Rating: 1 kW per axis

• Current Rating: 6 Amperes

• Rated Supply Voltage: 200 to 230 Volts AC

• Current Consumption: 9.8 Amperes

• Permissible Voltage Fluctuation: 170 to 264 Volts AC

• Power Consumption: 55 Watts

• Cooling Method: Forced ventilation cooling

• Control Method: Sine wave PWM control and current control

Furthermore, this drive has six digital inputs and four digital outputs. You can connect limit switches, sensors, and brake controls directly. The built-in dynamic brake and regenerative brake improve safety during sudden stops.

Protection and Environmental Ratings

The MR-J4W2-1010B carries an IP20 protection class. This rating protects against solid objects larger than 12mm. It does not protect against water. Therefore, you must install this drive inside a control cabinet. Keep it away from liquids and conductive dust.

Operating temperature should stay within 0°C to 55°C. Storage temperature ranges from -20°C to 65°C. Ambient humidity must remain between 5% and 90% without condensation. Following these conditions ensures long service life for the MR-J4W2-1010B.

Physical Dimensions and Weight

Weight is an important factor for panel mounting. The MR-J4W2-1010B weighs only 1.36 kg or 3.00 lbs. This light weight makes installation easy for one person.

Dimensions are as follows:

• Height: 168 mm (6.61 inches)

• Width: 85 mm (3.35 inches)

• Depth: 195 mm (7.68 inches)

These compact dimensions allow the MR-J4W2-1010B to fit in tight spaces. You can mount multiple units side by side efficiently.

Installation Guidelines

Follow these steps for a successful installation. First, mount the MR-J4W2-1010B vertically on a flat, metal panel. Leave enough space around the unit for airflow. Next, connect the main power supply to the correct terminals. Use the recommended wire gauge for 6 to 10 amperes.

Then, connect the SSCNET III/H cable to your controller. Use high-quality shielded cables for best results. After that, wire the motor power and encoder cables to each axis. Finally, connect all digital I/O signals. Always turn off power before making any connections. The forced ventilation fan needs free space to operate. Do not block the air intake or exhaust.

Frequently Asked Questions (FAQ)

1. Can I use the MR-J4W2-1010B with only one axis active?
Yes, you can operate a single axis. The unused axis simply remains idle. However, you still need to connect the power supply properly.

2. What type of motor works with this drive?
The MR-J4W2-1010B works with Mitsubishi HG series servo motors. Each axis supports up to 1kW continuous output.

3. Do I need an external reactor for this drive?
An external reactor is optional but recommended. It reduces harmonic distortion. For weak power supplies, a reactor improves stability.

4. How do I connect the regenerative brake?
The regenerative brake is built inside the MR-J4W2-1010B. You only need to connect an external resistor for high-inertia applications. Check the manual for resistor sizing.

5. Is this drive compatible with a 110V power supply?
No, the minimum rated voltage is 200V AC. Using 110V will trigger an undervoltage alarm. You must supply 200 to 230V AC for proper operation.
