  • NI 9403 pwm / mli fpga mode Updated:11-30

    Bonjour à tous, J'ai déjà une expérience de labview et je désire générer une pwm à une fréquence de 1KHz avec un NI 9024 + NI 9403, et ceux avec 100 valeurs différentes de rapport cyclique. Pour cela je réalise dans mon fpga, de façon cyclique, 100 i

  • Measure PWM with CRIO Module 9403 Updated:11-30

    Hi, I'm trying to measure a PWM signal generated by an absolute encoder. The encoder outputs a PWM with a period of approximately 1000 microseconds. This correlates to about 0.4 deg/microsecond. When I run an FPGA code that has a counter that counts

  • Generating PWM From NI 9403 Using LabView FGPA Updated:11-30

    Hi,  I have been working to try to generate a PWM wave using the Digital I/O card NI 9403 with no success. Does anyone have any ideas as to how to do this?  Thanks!!! Is there any way constantly be reading the value that the NI 9403 is outputting in

  • Ssr control without the use of pwm Updated:11-30

    i want to control the heater and a DC motor using the SSR. on checking for the solution i find that PWM with varing duty cycle is the best option but i don't know nothing about PWM and also how to program it on LabVIEW. i have a NI 9403 and NI 9478 D

  • Data acquisition of CV7-V wind sensor under labview using NI 9403 Updated:10-11

    hello I want to measure a numeric type RS232 signal at the output of a CV7-V wind sensor (attached PDF file) I used the module CDAQ 9191 and NI 9403 under NI MAX and I got the result on the attached figure how I can retrieve the information from this

  • Can i generate PWM output from digital out of my PCI 7041 RT DAQ card? Updated:10-11

    I want to generate 4 PWMs using my PCI7041 card. I do have only 2 analog outputs and 2 counters to output my signal that's why I want to use digital out of my card for PWM. How can I do that? If there is any example then please let me guide that way.

  • How can I vary a PWM´s duty cycle inside a while loop? Updated:10-11

    Hi, I'm using the "Generate Pulse" to generate pwm signals in counters 0 and 1 in order to drive a DC motor both ways. The problem is, I need to control the movement of the dc motor with my PI controller which is inside a while loop. I'

  • Can I use a Change Event with a NI 9403 module? Updated:10-11

    Hi, I would want to know if the NI 9403 supports a Change Detection Timing configuration to generate events for programming something like this thread and not polling the Digital Inputs:

  • How to generate a pwm whose duty cycle has to be varied depending on the frequency of the input trigger?? Updated:10-11

    Sir/madam, I am quite new to the Labview FPGA module.  I am currently working on an application where i have to generate a pwm to control the ON time duration . The pwm ON time depends on the frequency of an input signal.I want to retrieve the ON tim

  • PID control of Counters (PWM) Updated:10-11

    Hello everybody!! I work on a closed loop PID controlled problem (Labview 8.5) and I have a couple of questions in order to make some progress! Firstly, I have to declare that my loop is composed of 2 AI channels (2 accelerometers), 1 AO channel (exc

  • How do i create 6 digital 25Hz PWM output signals with my PCI-6221 card? Updated:10-11

    Hi! I´m a student, who´s trynig to control a gasturbine process for my diploma thesis. The control program should be written in LabView 8. I need to control 6 25 Hz PWM signals for the gasvalves. The  needed accuracy of the duty cycle has to be about

  • Problem when combinning PWM signal and Analog signal TOGETHER! Updated:10-11

    Hello everybody, first of all i have DAQmx 6212, and i need to run a small water pump (9V-16V) which needs to be driven by a PWM signal; also i have a motor (5V-13V) for a water valve that needs to be driven by a analog signal and it has a built in a
