NI 9759 User Manual
Introduction
The National Instruments 9759 Electronic Throttle Driver Module includes a CompactRIO
(cRIO) module for driving passenger car electronic throttle bodies up to 70 mm in diameter. A
typical example of electronic throttle bodies which this module is capable of driving is the Bosch
DV-E5 series which range from 32 mm to 68 mm in diameter. The module is capable of driving
most other electronic throttle bodies within that size range.
The NI 9759 includes a LabVIEW FPGA VI for controlling two H-Bridge driver channels
independently and a set of RT VIs which allow the user to calibrate the throttle control algorithm
in engineering units. The FPGA VI may be used by itself for driving any small DC motor other
than an electronic throttle. This manual will focus on the application of electronic throttle
position control. The features included are listed below:
Features
•
2-Ch. H-Bridge Drivers for dual electronic throttle control
•
2-Ch. analog input for throttle position feedback
•
Short circuit and over-temperature protection with fault reporting
•
Battery voltage, current sensing and module temperature measurements
•
LabVIEW FPGA VI for H-Bridge control and interface
•
LabVIEW RT VI for electronic throttle position control
•
External power supply of 7 V to 32 V
