FAQ – Network Integration & Application

What is the main advantage of using CC-Link with this drive?

It allows multiple servo axes to be controlled directly from a master PLC over a single network cable, drastically reducing control cabinet wiring, simplifying setup, and easing troubleshooting.

Can I use both CC-Link and RS-422 at the same time?

Typically, you use one primary method. CC-Link is for main networked control. The RS-422 port is often used for a separate connection, like to a teaching pendant or for direct parameter setup.

How does the "built-in positioning function" work?

The MR-J3-40T can store and execute simple position commands (like move to a set point) received over CC-Link, freeing the main PLC from complex real-time trajectory calculations for basic moves.

Is this model suitable for a clean environment like medical devices?

Yes. Its compact, self-contained design, precise control, and network capability make it a good fit. Ensure it's installed in a suitable enclosure to meet the specific environment's cleanliness standards.

What's the first thing to check if the drive doesn't appear on the CC-Link network?

Verify the station number setting on the drive's parameters matches its assigned address on the PLC's network configuration. Incorrect station numbers are a common cause of communication failure.
