Frequently Asked Questions

What size cabinet and cooling are needed for this IP00 amplifier?

• Install the MR-J3-22KB4RJ006 in a well-ventilated industrial cabinet rated at least IP54. You must provide adequate airflow around the unit, following the clearance dimensions in the manual, to prevent overheating due to its high power output.

Can I connect multiple motors to this single amplifier?

• No, this is a single-axis amplifier. It is designed to control one three-phase servo motor. For multi-axis systems, you need one amplifier per motor, all networked via SSCNET III.

How do I select the correct external regenerative resistor?

• The resistor selection depends on your motor's inertia and the braking cycle. Consult the amplifier's technical manual or Mitsubishi's sizing software. Using an undersized resistor will cause amplifier faults during deceleration.

Is this amplifier compatible with older MR-J2 series motors?

• While electrically possible, it is not recommended. For optimal performance and access to all features, pair the MR-J3-22KB4RJ006 with a compatible MR-J3 or later series servo motor. Always check the motor-amplifier combination list.

What is the advantage of SSCNET III over analog/pulse control?

• SSCNET III uses a digital, noise-immune fiber optic link. It allows for faster command updates, synchronous multi-axis control, and simplified wiring with fewer connections compared to traditional analog or pulse train interfaces.
