Frequently Asked Questions

What type of applications is this drive best for?
The MR-J3-20A is ideal for general-purpose machines requiring precise motion, like small conveyors, indexing tables, or pick-and-place units.

Does it need an external brake resistor?
No. This model has a built-in regenerative resistor, simplifying your cabinet layout and wiring.

Can I use it with a single-phase power source in a small workshop?
Yes. Its flexibility to accept single-phase input makes it a great choice for locations without three-phase power.

What is the main advantage of sine-wave PWM control?
It makes the motor run much smoother and quieter compared to older control methods, reducing vibration and wear.

How do I connect it for communication?
Use a standard RS-422 cable. This common interface allows for reliable data exchange over longer distances within your control system.
