Typical Applications

This amplifier is ideal for systems requiring external reference feedback:

• Electronic line shafting (ELS) for printing or converting machines
• Multi-axis gantry systems with a master encoder
• Position synchronization of independent actuators
• Machinery using linear scales for direct position feedback
• General automation (conveyors, feeders, etc.)

Compatibility & System Integration

The MR-J3-100BRJ006 is designed to drive 1kW-rated Mitsubishi HC-KFS, HC-MFS, or HC-SFS series servo motors. Its high-speed serial interface connects directly to compatible Mitsubishi detectors like the HG-KG series. It can be controlled via standard pulse train input from a PLC or CNC, while the serial interface handles the auxiliary feedback loop.

Professional FAQs

What is the purpose of the separate control circuit power (200-230VAC single-phase)?

It powers the amplifier's internal logic, I/O, and communication circuits. This isolation from the main motor power prevents electrical noise from disrupting the sensitive control electronics.

What type of devices connect to the "machine end detector interface"?

It connects to external feedback devices like absolute or incremental encoders, or linear scales, that are mounted on the machine (not the motor) to provide a second position reference.

Is the rated current of 0.2A correct for a 1kW drive?

The 0.2A likely refers to a specific control or logic circuit current. The main motor current for a 1kW drive at 200VAC would be significantly higher. Always refer to the detailed technical manual for wiring specifications.

Can this drive operate on a single-phase main power supply?

No. The specification clearly states the main circuit requires three-phase AC 200-230V. The control circuit, however, uses single-phase power.

Does this model have a built-in dynamic brake?

The product code does not specify. Many MR-J3 drives in this power range have a built-in brake resistor for handling common regenerative energy. Check the detailed specs or manual to confirm.
