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.

Page 3: Powering The Module
The external screw-terminal connector has terminals labeled BATT (0) and GND (9). Typical power sources will be from automotive 12 V or 24 V battery systems. The NI 9759 can accept power from a range of 7 V to 32 V. However, the H-bridge power stages have a minimum voltage requirement of 11 V. -

Page 5: Analog Inputs
Analog Inputs The NI 9759 provides two external analog inputs for accepting 0 V to 5 V signals. The primary purpose of these inputs is for measuring potentiometer voltages. A regulated 5 V output and ground terminal is provided for powering the potentiometer(s) of an electronic throttle body. - Page 6 H1A - Motor – H2B - Motor + H2A - Motor – 5 V Out - Position Ref.

Page 7: Throttle Control
NI 9759. Throttle Control NI provides a flexible throttle position control algorithm with the NI 9759. Follow the throttle control example included in the driver package for implementing throttle control in your engine control application. Perform throttle control at a rate of 100 to 200 Hz, even if your engine control algorithms require execution at another rate, a separate timed loop can be created to implement throttle control. - Page 8 If this VI is used for position, a filter is not required. Begin control calibration with zero for all Lead/Lag, PID and compensation calibration parameters. Begin tuning PID gains for angles above ThetaLH. 8 | ni.com | NI 9759 User Manual...
