Hi,
I am planning for an applicaition in LabVIEW for motion control using a 4-axes motion card of which two have to be synchronized for a horizontal movement and the 3rd axis will drive the vertical movement.
Can I use the function "Load DAC.flx" in my application ?

Herok,
"Load DAC.flx" just sets the value of an analog output but this is not the way how you want to drive an axis, as this method doesn't provide any trajectory generation or real-time control. NI-Motion devices run the trajectory generation and the PID control onboard, so all you have to do is to load the move constraints (target position, velocity, acceleration) and send the start command in LabVIEW. The motion control board does the rest for you. Please refer to the examples that ship with NI-Motion to learn more about the NI-Motion API.
Kind regards,
