Count pulses from one counter and give pulse train output from the other (PCI 6220)

[Giridhar_Rajan]

Hi,

I have a stepper motor with an encoder. I want to give pulse train output to move the stepper motor and also take f/b from the encoder to display the angle of rotation. I have created a VI for generating pulses which works fine. Another VI to read pulses which also works fine. But when I put both of them together, I get a DAQ error. Is it not possible to use both counter together?

Further info: I'm rotating in only one direction and the positional accuracy is not critical, hence I didn't use a motion controller.

Rgds,

Hey!

Which error do you get? Which card are you using?

I guess your pulse train generation (it depends on if it is a finite or continous generation) needs two counters, because of that you get an resource error.
