hello to all.

I would like to create a VI to control a step motor to run certain numbers of steps... but I am not even close to have that experience on Labview programing

An example would be if I set on VI that I want 120 steps it would send 120 "steps"

I am using a H-bridge controled by Ni Myrio and step motor model PM55L-048-HPG9, The brand is NMB it has 7º between steps. 

Please could you help me?

Best regards

You can use this code to generate Definite pluse

Hello Mr Sankar

Thanks for the help..

But I need something close to what I did that is attached.. but my one Ican control the number of steps

The VI I'have attached I can control the step motor by case of structure that has for interactions that change the pulse position to control the H-Bridge and make step motor step out.

I justwant to control how many times I can make it change the case structure position

best regards

For the counting operation you have to use shift register or feed back node. Please Refer this link
