c.
Slide the controller onto the controller slot on the chassis. Press firmly to ensure the chassis
connector and the controller connector are mated.
d.
Using a number 2 Phillips screwdriver, tighten the two captive screws on the front of the
controller.
2.
Connect the controller to a power supply and an Ethernet network on the same subnet as the
development computer. Refer to the controller operating instructions for information about wiring
the controller to the power supply and Ethernet network.
Note
Do not plug in or turn on any power to the system until after you complete
the Drive and Connect the Motor and Encoder to the Drive
.
3.
Install the NI 9512 module in slot 1, 2, 3, or 4 of the chassis.
Step 2: Connect the NI 9930M Connection Accessory
The NI 9930M connection accessory contains connections for the NI 9512 C Series module, the
Mitsubishi MR-J2 or MR-J3 servo drive, and a 24 V power supply for NI 9512 module and drive I/O.
1.
Connect the NI 9512 module to the NI 9930M J4 connector using the NI 951x Y cable.
2.
Connect the NI 9930M to the drive.
•
Mitsubishi MR-J2
—Connect the J2 connector to the CN1A connector on the drive, and the
J6 connector to the CN1B connector on the drive using two 20-pin MDR cables.
•
Mitsubishi MR-J3
—Connect the J3 connector to the CN1 connector on the drive using one
50-pin MDR cable.
3.
Connect a 24 V power supply to the Vsup and COM terminals on the NI 9930M accessory J8
connector. Figure 3 shows the location of the power supply input.
4.
Connect pin 2 (EMG - emergency stop input signal) and pin 1 (COM) to an emergency stop switch.
Refer to the drive manual for more information about emergency stop switch requirements.
Note
If the emergency stop functionality is not required, connect the EMG input directly to COM
to bypass any external safety circuitry.
Note
You cannot enable the drive if you do not connect the EMG input to an emergency stop switch
or directly to COM.
5.
Connect pin 15 (LSP - forward rotation stroke end/forward limit) and pin 14 (LSN - reverse rotation
stroke end/reverse limit) to pin 13 (COM), or configure the drive to ignore limit inputs.
Note
These configuration settings disable limits for initial setup and testing purposes. National
Instruments recommends connecting and enabling limits in your final application. Refer to the drive
documentation for limit input requirements.
6.
Connect pin 9 (COM) to pin 10 (LG - control common).
Note
Not connecting pin 9 and pin 10 will result in unpredictable behavior.
7.
Connect any additional I/O, such as limits, DIO, position compare outputs, position capture inputs,
and so on, using the NI 9930M screw terminal connectors. The J1 and J5 connectors allow
connection to the drive I/O signals, and the J7 connector provides connection to the NI 9512 I/O
signals. Refer to the drive or the NI 9512 module documentation for specific signal connection
requirements.
