Overview

Product overview

Key product information and technical features.

NI employee guidance identifies the MCA-7790Y connector board as a recommended companion to the PCI-7390 in a position-command drive system. This supports the adapter-family context, but does not establish that this unsuffixed MCA-7790 catalog item is the Y variant.

NI documentation describes dedicated PCI-7390 cable and connection hardware for Yaskawa Sigma II, Mitsubishi MR-J2S, and Panasonic Minas A drives. Treat these as system-level options, not a statement that one unidentified adapter supports all three drive families.

Drive-specific connector-board selection; NI employee guidance explicitly identifies an MCA-7790Y version.
Associated with position-command drive integration rather than a standalone motion controller.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does this record identify a specific MCA-7790 drive variant?

No. The supplied model is MCA-7790 without a drive-specific suffix or manufacturer part number. NI employee guidance names an MCA-7790Y connector board, but that does not identify the variant represented by this record.

Can one MCA-7790 adapter be assumed to connect all listed drive families?

No. NI lists dedicated PCI-7390 cable and connection options for Yaskawa Sigma II, Mitsubishi MR-J2S, and Panasonic Minas A. Verify the exact adapter variant and cabling for the intended drive rather than assuming universal compatibility.
