Frequently Asked Questions

Can this amplifier run on 110V or 120V power?

• The MR-J3-40B1 is designed for 100V AC input. While 110V might work temporarily, it is outside specification and can cause premature failure or unstable operation. Always use a transformer to provide the correct 100V supply.

What is the typical application for a 0.4kW servo drive?

• This drive is ideal for small automation: pick-and-place units, small conveyors, rotary tables, valve actuators, and precision instruments where compact size and accurate positioning are key.

Do I need a special cable for SSCNET III connection?

• Yes, you need a Mitsubishi SSCNET III fiber optic cable (e.g., MR-J3BUS*M). Standard electrical cables cannot be used for this high-speed, noise-immune communication.

How do I know if I need an external regenerative resistor?

• If your application involves frequent stopping or reversing of a high-inertia load, you likely need one. The drive manual provides guidelines. If the internal capacity is exceeded, the drive will generate an alarm.

Is parameter setting complicated for this amplifier?

• Basic operation is straightforward using default parameters. For advanced tuning (gains, filters), you use Mitsubishi's MR Configurator software, which provides a user-friendly interface for setup and optimization.
