GETTING STARTED
NI 7330/7340/7350 Motion Controllers and
P7000 Series Stepper Drives
This manual helps you quickly install and configure the P7000 series stepper drives and stepper motors
for use with NI 7330, NI 7340, and NI 7350 motion controllers. It assumes you have already installed
your National Instruments motion controller and driver software. The driver CD installs the
NI Measurement & Automation Explorer (MAX) configuration files and documents referenced in this
manual. You can find all the software, files, and documents at
Additionally, this manual assumes you are using either the NI Universal Motion Interface (UMI)-7764
or NI UMI-7774/7772 and have the appropriate 68-pin cable for connecting to your NI motion
controller. Refer to the NI Stepper Motion System Selection Guide at
assistance. For specifications or installation questions about your NI motion controller or NI UMI, refer
to the appropriate user manual.
