how can i make a analog ouput

[jerrywu]

i download the ni's example -- Analog_Output,the example is an cvi file.A

[jerrywu]

and this file can't work.If i want to do as this,how can i do?

the purpose i want to make a voltage which i can change.i have done by myself. i use the code FLEX_LOAD_DAC.
but i use machine to measure the AOUT,it also 0 volt.how can i make the volt which i want to need?

Hi Jerry,

A lot of how you set up your system depends on what type of hardware you are using. Are you using a 7334? 7344? What version of the Motion driver do you have for CVI/ Let us know and we'll be glad to help you out.

Hi Jerry,

Here is what you will need to do in order to get your output signal:

1. Make sure that the PCI 7344 is properly set in a PCI slot
2. Make sure that you have NI-Motion installed. The latest version is Version 6.1.5
3. Go into Measurement & Automation Explorer (MAX) and make sure that the board appears under "Device and Interfaces"
4. Configure the axes you want to control as either stepper or servo. I'm guessing since you are concerned with analog voltage that you are using a servo motor.
5. If oyu are in fact using a servo motor, make sure you properly connect all motor and encoder connections.
6. Once you ahve configured the axis, initialize the board.Test the board out using the "Interactive" options in MAX.
7. Once you have verified that the board works there, then try running a simple CVI example like ones that install with the motion driver. Make sure that the board ID in your program matches the board ID in MAX.

Glad to help any time.
