Signal Connections; Motion I/O Connector - National Instruments PCI-7340 User Manual And Specifications

Signal Connections

This chapter describes how to make input and output signal connections directly to the National
Instruments PXI/PCI-7340 as well as general information about the associated I/O circuitry.
The NI 7340 motion controller has three connectors that handle all signals to and from the
external motion system.
• 68-pin motion I/O connector
• 68-pin digital I/O connector
• RTSI connector
You can connect to your motion system with cables and accessories, varying from simple screw
terminal blocks to enhanced Universal Motion Interface (UMI) units and drives.
Note The NI 7340 motion controller does not provide isolation between circuits.
Caution
NI 7340 motion controller controller motion I/O and auxiliary digital I/O cables.
Failure to do so may damage the controller.

Motion I/O Connector

The motion I/O connector contains all of the signals required to control up to four axes of servo
and stepper motion, including the following features:
• Motor command analog and stepper outputs
• Encoder feedback inputs
• Forward, home, and reverse limit inputs
• Breakpoint outputs
• Trigger inputs
• Inhibit outputs
The motion I/O connector also contains four channels of 12-bit A/D inputs for analog feedback
or general-purpose analog input.
