Use a motion board for a servo valve

[gepponline]

Hi!

   I'm developing an application to control an hydraulic servovalve with feedback.
I already have a motion board and I'd like to know if and how is possible to use the PCI-73xx servo board to control a servovalve 'cause it don't work in speed but with trajectory so i will not give a speed reference but a position curve.

Just think of the motion controller as a PID controller.  As long as it can provide the proper control signal and read the proper feedback signal, it is really just a matter of tuning.  Not sure if you are controlling the position of the servovalve itself or controlling the position of an actuator.

With analog reference I control Flow, but the feedback read the position of the actuator at which the valve is connected

Then it should work fine.

But how to send a waveform to the controller?
Usually i set a speed and the motor start run.
Now I have to set a waveform. Is there a VI to send a compleate waveform and leave the board to execute and follow the waveform continuously?

You are talking about 2 different issues.  I think we established that you can control the position of the actuator using the motion controller.  Do a search on sending waveforms, and I believe you will find some answers.
