Description

Engineered for high-speed, high-precision motion control, the Mitsubishi Electric MR-J4-100B operates within the MELSERVO-J4 series as a high-performance servo amplifier. Rated for a 1.0 kW capacity and designed for a 200V class voltage input, this unit utilizes the advanced SSCNET III/H command interface to achieve sub-millisecond communication cycle times, making it ideal for highly synchronized multi-axis architectures. The amplifier features integrated functional safety elements, absolute encoder compatibility, and robust vibration suppression algorithms to guarantee stable operation in heavy industrial deployments.

Features

High-speed fiber optic SSCNET III/H communication supporting ultra-low cycle times down to 0.222 ms.
Integrated functional safety with STO (Safe Torque Off) capabilities certified to EN ISO 13849-1 Category 3 PL e and SIL 3 standards.
Built-in dynamic brake to quickly and safely decelerate servomotors during unexpected power cuts or system stops.
Advanced control functions including robust filters, adaptive vibration suppression, and real-time machine diagnostic utilities.
Supports full closed loop control with high-speed serial encoder interfaces.

Applications

Multi-axis coordinated packaging systems and high-speed labeling machinery.
High-precision semiconductor fabrication and pick-and-place equipment.
Machine tool feed axis mechanisms requiring synchronous interpolation.
Automated material handling and automotive assembly gantries.

Empirical Engineering Insights

Alternative Models & Compatibility

The MR-J4-100B can replace legacy J3 series amplifiers (specifically the MR-J3-100B) by engaging the integrated J3 Compatibility Mode parameters via MR Configurator 2. Ensure that physical dimensions and terminal locations are verified, as J4 footprint revisions may require adapter mounting brackets inside older electrical cabinets.

Application Pitfalls & Engineering Notes

When utilizing single-phase AC 200V input configuration for the main power circuit, close-mounting installation with multiple amplifiers nested side-by-side is not supported due to elevated thermal generation. Provide adequate spacing between drives under single-phase supply to avoid premature thermal trip faults.

Commissioning & Wiring Tips

The SSCNET III/H fiber optic cables (connected via CN1A/CN1B) must not exceed a minimum bending radius of 25 mm. Exceeding this limit degrades the light transmission path, triggering intermittent AL.37 (Parameter Error) or AL.85 (SSCNET Communication Error) faults during dynamic machine cycles. Always keep the unused fiber ports sealed with protective caps.

Installation Guidelines

CRITICAL WARNING

Disconnect all main and control power lines before terminating terminal blocks or handling interface cables. After switching off the incoming power supply, wait at least 15 minutes for the internal bus capacitors to fully discharge. Always verify that the charge LED on the front panel is completely unlit before proceeding with electrical installation.

Mount the servo amplifier vertically on a flat, non-flammable surface inside a sealed IP54 minimum cabinet to protect against dust and conductive contamination.

Ensure minimum clearances of 40 mm above and below the cooling fins, and at least 10 mm on both sides for adequate convective airflow dissipation.

Verify CN8 safety shorting connector is securely installed if external safety logic is not routed through the STO system. Without a proper safety input path, the unit will remain in a permanent safe torque shutdown state.

Can the MR-J4-100B be powered with a single-phase AC supply?

Yes, the MR-J4-100B main circuit supports single-phase AC 200V to 240V input. However, under single-phase operation, close-mounting of multiple amplifiers side-by-side is not allowed due to specific heat dissipation restrictions.

Which software is used to program and tune the MR-J4-100B?

Commissioning, auto-tuning, parameter editing, and diagnostics are performed using MR Configurator 2, which connects directly to the amplifier via its integrated mini-USB port.

What is the function of the CN8 safety connector on the MR-J4-100B?

The CN8 interface handles safety inputs for Safe Torque Off (STO) functions conforming to EN ISO 13849-1 Category 3 PL e and SIL 3. If external safety relays are not used, a standard dummy plug must be connected to enable normal operations.

How do I resolve communication errors over the SSCNET III/H network?

Ensure that the SSCNET III/H fiber optic cables connected to CN1A and CN1B do not violate the minimum bending radius of 25 mm. Always keep optical connection tips clean and capped when disconnected to avoid dust contamination.
