interfacing of hardware with labview

And read the manual for the instrument. You should first setup all of the parameters manually before attempting to write any code.

Thank u for the suggestion..... but one thing i wanted to ask u about....... i'm using a stepper motor for my project and there is no labview driver for that can u give  me an alternate dolution for that....... and pls do tell in details

[Dennis_Knutson]

What are you talking about now? Is the stepper connected to the Keithley? If not, what is? You would also need to provide the make and model of the stepper.

You need to solve one problem at a time.  Otherwise your code will be a mess.. Like spagetti & meatballs..

Start with the Keithley to get familiar with LabVIEW

I'll tell what my project actually is...... there is a horizontal board where we will keep the solar cell and there will be a stepper motor attached to move a lazer beam on the solar cell in the X-Y directions...... when it moves along X-Y direction we have to measure the current and voltage using keithley source meter..... this is the overview of my project

[Ray.R]

Thanks.

So what would you like to start with?  Keithley sourcemeter to which I provided links to the drivers.

or

USB-6009 which I suspect you are using to actuate and monitor the stepper motor..

??

Thanks for the reply...... can u pls give me the details of both in stepwise manner...... because i´m new to labview...... can u pls also provide me the block diagram of wht actually happens....... actually i don`t have drivers of labview for steppe motor(stepper motor is from oriental ) what i shloud for that...... pls give me some alternarives for this

[Dennis_Knutson]

Alternative to what? You still have not provided any information about the stepper and what it requires. Without this basic information, how can you expect anyone to help you? Have you tried to find any of the information yourself. Do you see the searcj options?

Based on your previous post, I was guessing that you were using a USB-6009 DAQ device... 

What DAQ card do you actually have? Ideally, you would need a DAC card that has a counter output to generate the steps, where you can control frequency. If you try to start the motor too fast (acceleration or abrupt application of fast pulses) it may stall out.  In the Help menu, select Search for Examples and do a search for keywords 'frequency' and 'pulse'.  You should see some examples of frequency generation.  You can also use a digital output on the DAQ card to control the direction of the motor.

If the DAQ card does not have a counter, you could implement a software timed loop to toggle the digital output and generate the pulse train.  It may have limitations for your application.

If you are using a USB-6009, you may need to implement an amplifier circuit to drive the motor windings as the USB-6009 has a very limited voltage/current output  Actually, unless you go to PXI, I doubt that any DAQ cards can source or sink the power levels you'll need to drive a stepper motor.

 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.....
