Frequently Asked Questions (FAQ)

In which regions or applications is a 100V servo amplifier commonly used?

The MR-J3-10T1 is prevalent in regions like Japan and North America, where 100VAC single-phase power is standard in workshops and light industrial settings. It's used in smaller CNC machines, packaging equipment, and automated assembly stations.

When should I use CC-Link versus the RS-422 interface?

Use CC-Link when integrating the drive into a multi-device Mitsubishi PLC-based control network for centralized monitoring and control. Use RS-422 for simpler, direct point-to-point connection to a controller or for initial parameter setup and tuning from a PC.

What are the advantages of natural cooling?

Natural cooling (fanless) makes the amplifier silent, more reliable (no fan to fail), and resistant to dust accumulation that can clog fans. It is suitable for environments where noise is a concern or where the thermal load is well-managed within an enclosure.

What is a key consideration when sizing a motor for this amplifier?

Beyond matching the 0.1kW power rating, pay close attention to the motor's rated current and peak current. Ensure the motor's continuous current is at or below the amplifier's 1.1A rating, and that the amplifier can supply the motor's required peak current for acceleration.

The amplifier trips on overvoltage during deceleration. What is the likely cause?

This is often caused by excessive regenerative energy from the motor during fast stops or high inertial loads. The internal regenerative resistor may be insufficient. Solutions include increasing deceleration time, reducing load inertia, or adding an external regenerative resistor option if supported.
