NI Motion Controller Configuration and
Installation
Caution Before installing the NI 7340/7350 motion controller refer to the user
manual appropriate to your controller for safety and specification information.
Failure to follow safety instructions may result in damage to equipment.
Step 1: Install NI-Motion
You must install the NI-Motion driver software before installing an NI motion controller for the
first time. If you are upgrading from a previous version of NI-Motion, it is not necessary to
remove the NI motion controller before installing the upgrade. The upgrade does not affect the
existing Microsoft Windows configuration.
Note If you are using a Real-Time OS, install LabVIEW Real-Time on the
development computer before installing NI-Motion so that the RT support files
install.
Complete the following steps to install the NI-Motion driver software:
1. Insert the NI-Motion CD into the CD-ROM drive to display the NI-Motion installation
screen.
2. If you have autorun enabled, autorun.exe runs automatically. Otherwise, double-click
autorun.exe.
3. Follow the onscreen instructions.
Note You must update the firmware on your NI motion controller(s) before you can
use them with the corresponding version of NI-Motion. Refer to Step 1: Update
Firmware on the Motion Controller in the Software Installation and Configuration
section for detailed instructions.
Step 2: Install the NI 7340/7350 Motion Controller
The following sections explain how to install PXI and PCI motion controllers.
Note When adding or removing the motion controller, you must be logged on with
administrator-level access. After you have restarted the system, you may need to
refresh Measurement & Automation Explorer (MAX) to view the new controller.
PXI Controllers
1. Power off and unplug the chassis.
Caution To protect yourself and the computer from electrical hazards, the
computer must remain unplugged until the installation is complete.

6|ni.com |Getting Started with NI 7340/7350 Controllers and AKD Drives
2. Choose an unused peripheral slot and remove the filler panel.
3. Touch a metal part on the chassis to discharge any static electricity that might be on your
clothes or body. Static electricity can damage the controller.
4. Insert the PXI controller into the chosen slot. Use the injector/ejector handle to fully secure
the device into place.
5. Attach the front panel of the PXI controller to the front panel mounting rails of the chassis
with the slot screws on the chassis.
Caution Make sure you have correctly connected all safety devices before you
power on the motion system. Safety devices include inhibits, limit switches, and
emergency shut down circuits.
Caution Always power on the computer containing the motion controller and
initialize the controller before you power on the rest of the motion system. Power off
the motion system in the reverse order.
6. Plug in and power on the chassis.
PCI Controllers
1. Power off and unplug the computer.
Caution To protect yourself and the computer from electrical hazards, the
computer must remain unplugged until the installation is complete.
2. Open the computer case to expose access to the PCI expansion slots.
3. Touch a metal part on the chassis to discharge any static electricity that might be on your
clothes or body. Static electricity can damage the controller.
4. Choose an unused +3.3 V or +5 V PCI slot, and remove the corresponding expansion slot
cover on the back panel of the computer.
5. Gently rock the controller into the slot. The connection may be tight, but do not force the
controller into place.
Note Check that the bracket of the device aligns with the hole in the back panel rail
of the computer chassis.
6. Secure the mounting bracket of the controller to the back panel rail of the computer.
7. Replace the cover.
Caution Make sure you have correctly connected all safety devices before you
power on the motion system. Safety devices include inhibits, limit switches, and
emergency shut down circuits.

Caution Always power on the computer containing the motion controller, and then
initialize the controller before you power on the rest of the motion system. Power off
the motion system in the reverse order.
8. Plug in and power on the computer.
Step 3: Install Software on and Configure the RT PXI
Controller (PXI 7340/7350 Only)
Note This step is only required if you are using a PXI-7340/7350 motion controller
and an RT PXI controller. If you are not using an RT PXI controller, skip to the
NI UMI and AKD Servo Drive Configuration and Installation section.
Complete the following steps to configure the controller and install software on it.
Note The Measurement & Automation Explorer (MAX) user interface may not
match these steps exactly depending on which version of MAX you are using.
1. Boot the NI PXI embedded controller into the real-time operating system. The PXI
controller automatically boots into LabVIEW RT Safe Mode when no software is installed.
LabVIEW RT Safe Mode loads with the basic real-time operating system and automatically
attempts to connect to the network using DHCP. If DHCP is not available, the controller
connects to the network with a link-local IP address.
Tip You can connect a monitor to the PXI to display startup messages such as the
IP address and MAC address.
2. Launch Measurement & Automation Explorer (MAX) on the development computer by
clicking the MAX icon on the desktop ( ), or by selecting Start»All Programs»
National Instruments»Measurement & Automation.
3. Expand the Remote Systems branch. MAX lists the PXI controller as the model name of
the controller followed by the MAC address (for example, NI-PXI-8104 00802f108562).
Tip Record the PXI controller MAC address, located on the side of the controller,
for use in identifying the controller. The label also can be removed and placed on the
front of the controller for easier access. If you have connected the PXI controller to a
monitor, the MAC address also appears when the PXI system boots up.
4. Select the System Settings tab and type a descriptive name for the system in the Name
field.
5. (Optional) Complete this step only if the target has an empty IP address (0.0.0.0). Select the
Network Settings tab and select DHCP or Link Local from the Configure IPv4 Address
list to assign an IP address or select Static to specify a static IP address in the IPv4 Address
section.
6. Click Save on the toolbar and let MAX reboot the system.

8|ni.com |Getting Started with NI 7340/7350 Controllers and AKD Drives
7. When the new system name appears under Remote Systems, expand the controller item in
the tree, right-click Software, and select Add/Remove Software.
8. Install the LabVIEW Real-Time software and NI-Motion on the RT target. Go to
ni.com/info and enter etspc for the latest information about supported software.
9. Click Next to install the selected software on the controller. Click Help if you need
information about installing recommended software sets.
10. Expand the Devices and Interfaces item under the PXI system.
11. Right-click the remote motion controller icon and select Map to Local Machine. This
assigns a local board ID to the remote motion controller in the host system.
Mapping the remote controller into the local system allows you to configure the controller
through MAX exactly as you would a controller that is in the host system. You can initialize
the controller, download firmware, and use the interactive and configuration panels exactly
as you would on a controller installed in the host machine. You also can write VIs using the
remote motion controller through the local board ID assigned to it.
This allows you to write and debug your VIs on the host, and then download them to the
remote system when you are ready. All you need to change is the board ID in your VI from
the locally assigned Board ID to the ID assigned by the remote system.
12. Browse to Devices and Interfaces under My System, where there is a shortcut icon next
to a new controller name.
For example, if the motion controller on the remote system is a PXI-7354, and the remote
system has an IP address of 123.45.678.9, then the shortcut device would show a name
like PXI-7354 (X) on 123.45.678.9 (Y).
Xis the board ID assigned to the board by the remote system. Use this board ID for VIs that
are downloaded to the remote system through LabVIEW RT.
Yis the board ID assigned to the remote motion controller by the local system. Use this
board ID for any VIs that run on the host and use the remote motion controller.
13. Close MAX.
