interfacing of hardware with labview

[interfacing with labview]

HI ,

             I have a stepper motor and a NI DAQ USB 6009 card...... I don't know how to start with programming of stepper motor..... can u pls give me the steps in detail....... so that i can get a overview of a project.....

You can use the analog output of the DAQ to drive (indirectly) your stepper motor.  Indirectly, because it is not likely that USB has enough power to drive it or to avoid damaging your USB interface due to excessive current draw.  So from your DAQ, you could go to an amplifier circuit which would be driving the motor.

There are many examples of code to output analog (or digital) signals from your DAQ.  I'd have to go back and look at the entire thread to see if you  mentionned which version of LabVIEW that you are using.  If you did not mention it, which version are you using?

Hi,

     Thanks for the information...... i'm using labview version 9...... i have a controller and driver for running a stepper motor..... the main thing is how shld i start programming for that...... if u can give me a proper idea or a block diagram of how it works it will be more helpfull for me..... i'm using a 5phase stepper motor.....

Did you receive the manual / instructions for the controller? 

How do they recommend interfacing with the controller? 

Does the controller expect commands?  Does it expect digital or analog signals?

Does the controller expect PWM (pulse-width modulation)?

You mentionned driver.  Does it have an API?  Is it a dll?  Do they supply LabVIEW drivers? 

In other words, what does the driver "look like" and does it have documentation?

We will need more details on what is the recommended interface to the stepper motor controller and its driver.

HI,

          i have NI usb 6009 DAQ, multimeter and i have labview verson 9....... can u pls tell how to generat pulses using daq......  pls give me detailed explanation about this...... if u have any examples pls notify me

Are you trying to build an LBIC?

Hi,

     no actually..... i,m trying to run stepper motor using NI usb daq 6009...... i wanted to make some self test that's why i'm using multimeter....... pls give detailed explanation about how to do it

If you open NI Example Finder (click on Help > Find Examples), then browse to Hardwadware Input and Output > DAQmx > Generating Digital Pulses

There are multiple examples on generating digital pulses.

Hi,

              As u told there are multiple examples but i cannot configure my USB DAQ 6009 with the examples of pulse generation............. can u pls tell how to do it...... pls tell me in detail

Hi,

          i have a doubt as i know NI USB DAQ 6009 doesn't have counter so how do we generate pulse using this device...... for runnig a step motor ..... i tried examples for pulse width generation but my device NI DAQ USB 6009 is not under the list...... so pls help me how to proceed\
