Motion Connection Accessories
This appendix describes the Motion Connection Accessory (MCA)
connectivity blocks for direct connections between the NI PCI-7390 and
Mitsubishi, Panasonic, and Yaskawa drives.
Mitsubishi J2S Series Drive Connection Accessory
The NI MCA-7790M accessory (NI part number 779612-01) provides
connection between the PCI-7390 and Mitsubishi J2S series drives.
Connecting Mitsubishi Drives to the PCI-7390
To connect a Mitsubishi drive to the PCI-7390, connect two 20-pin cables
from the drive to the MCA-7790M, then connect a SCSI 100-pin cable
from the MCA-7790M to the PCI-7390. Finally, connect the MCA-7790M
to a +24 V power supply using the IGND +24 V two-terminal screw
terminal.

Note
The Inhibit-Out (Servo ON) input in the drive is sourcing. For compatibility between
the drive and the controller, set the general-purpose output jumper on the PCI-7390 for
sinking. The MCA-7790M internally connects VI_COM <1..4> to +24 V which
configures all PCI-7390 inputs as sourcing.
