Description

Operating as a multi-axis drive solution within the MELSERVO-J4 platform, the MR-J4W3-222B servo amplifier provides independent closed-loop control for up to three AC servo motors. Designed to reduce cabinet footprint and simplify wiring complexity, this unit integrates three drive axes into a single physical housing while sharing a common power supply bus.

The MR-J4W3-222B utilizes the SSCNET III/H high-speed optical network interface to achieve synchronous, real-time motion control with minimal transmission delay. This communication protocol ensures high noise immunity and fast cycle times, making the amplifier highly compatible with Mitsubishi motion controllers and Q-Series or iQ-R Series PLC systems. By managing three axes with a single network connection, system integration is significantly streamlined.

Features

Three-axis configuration saves panel space and reduces total system component count.
SSCNET III/H fiber optic network interface ensures high-speed, noise-free communication.
Supplements precise motion profiles with advanced vibration suppression and real-time auto-tuning functions.
Common DC bus system improves energy efficiency by allowing regenerative energy to be shared among active axes.
Compatible with high-resolution rotary and linear encoders for high-precision positioning.

Applications

Multi-axis robotic assembly lines and pick-and-place systems.
Semiconductor manufacturing and electronic component insertion machinery.
High-speed packaging, labeling, and sorting systems.
Precision XY-Z positioning tables and multi-axis CNC machines.

Installation Guidelines

Mounting: Install vertically on a flat, clean metal plate within a sealed control cabinet to facilitate proper convective cooling.
Clearance: Maintain at least 10 mm of clear horizontal space on either side and 40 mm of vertical space above and below the amplifier.
Fiber Optic Handling: Ensure that SSCNET III/H fiber optic cables do not exceed their minimum bending radius of 25 mm during installation to prevent transmission loss.
Grounding: Connect the Protective Earth (PE) terminal of the amplifier to the cabinet ground bar using a low-impedance conductor.

FAQ

How many axes can the MR-J4W3-222B servo amplifier control?

The MR-J4W3-222B is a 3-axis amplifier capable of controlling up to three AC servo motors independently from a single unit.

What does the '222' designate in the MR-J4W3-222B model number?

The '222' indicates the rated output power for each of the three axes. In this configuration, Axis A, Axis B, and Axis C are each rated for 0.2 kW (200 W).

What communication network does this servo amplifier use?

It uses the SSCNET III/H high-speed optical fiber motion network, which connects to compatible Mitsubishi Motion Controllers or Simple Motion Modules.

Can I use single-phase power for the main circuit input of this drive?

No, the MR-J4W3-222B requires a 3-phase 200 VAC to 240 VAC power source for the main power input to guarantee rated performance across all three active axes.
