Description

Designed for high-precision motion control applications, the MR-J4-200B functions as a high-performance rotary servo, linear servo, and direct drive motor controller within the MELSERVO-J4 platform. This unit interfaces seamlessly via the high-speed SSCNET III/H synchronous network, enabling highly synchronized multi-axis operations with minimal transmission delay.

Operating on a 200V class voltage input, this unit delivers a rated output capacity of 2000W (2.0 kW). It incorporates advanced diagnostic and machine-tuning capabilities, including real-time vibration suppression and a "tough drive" function that prevents sudden shutdowns by automatically adjusting parameters during transient overloads or temperature spikes.

Features

High-speed SSCNET III/H communication interface for precise multi-axis synchronization and rapid control cycles.
One-touch tuning functionality that automatically configures gain and vibration suppression for optimal mechanical load matching.
Built-in Safe Torque Off (STO) function complying with EN ISO 13849-1 Category 3 PL e and IEC 61508 SIL 3.
Real-time friction and vibration monitoring to support predictive mechanical maintenance schedules.
Forced cooling mechanism combined with an IP20 protective structure for reliable performance inside control cabinets.

Applications

Automated assembly and multi-axis robotics systems
Packaging, wrapping, and labeling machinery
Semiconductor and flat-panel display manufacturing equipment
High-speed material handling and gantry positioning units
Precision machine tool axes

#MELSERVO-J4 #Servo Amplifiers

What is the primary communication network interface for the MR-J4-200B servo amplifier?

The MR-J4-200B servo amplifier utilizes the SSCNET III/H high-speed optical fiber network interface, enabling synchronous multi-axis control with very low latency.

Can this amplifier be powered with a single-phase AC supply?

Yes, the MR-J4-200B supports both single-phase and three-phase AC input in the 200V voltage class.

What safety functions are built into the MR-J4-200B?

It features a built-in Safe Torque Off (STO) safety function, accessible via the CN8 interface, compliant with EN ISO 13849-1 Category 3 PL e and IEC 61508 SIL 3.

Does this module require external cooling?

The MR-J4-200B has built-in forced cooling fans; however, it must be installed in a control cabinet with adequate clearance (10mm sides, 40mm top/bottom) and a maximum operating temperature of 55 Celsius.
