how to control 2 motors

[craigc]

Hi Gerd,

I think he wants to move the X axis motor and the Y axis motor simultaneously.

The problem with that is by the looks of thing he has 2 DAQ assistants in the one while loop so I am guessing they wont run in parallel.  Whats need is a multifunctional DAQ type OP which OP's both signals at the same time.  In order to do that you will probably have to move away from the DAQ express vi's and look at some of the DAQ examples for multiple analogue OP etc.

Edit: Scratch that, I am even more confused after reading it the second time :s

hi craigc

what you said exactly what I want

I want to move x and y simultanusly

I will try to find multifunction DAQ

thank you

Please any help

until now i didn't find the solution

😞

thank you

Try to get rid of the express vis.

init the joystick and one DAQ task outside the loop

read the joystick and calculate the needed output to the DAG

write the DAQ output 

close the DAQ after loop finished

Hi,

     First of all like you mentioned in your first post that only one moor ( X axis) works and the other ( Y axis ) doesn't work. Could you interchange the motors and see what the results are? ( I assume you would have tried that out already) If working fine, could you wire programatically the X input to Y and vice- versa?

Well, you can also simply add channels in one DAQ assistant for multiple analog output generation. Also as requested , post your VI?  and let us know how exactly you are controlling the motor ie.do you have drives which work on the analog signal they recieve etc?
