How to control an actuator that do not have an integrated controller?

[rczone]

Hi,

I am using a PCI 7330 and  UMI-7764 and I would like to know how can I control an actuator that works with 5Vdc using these devices.

I was thinking to use an analogic output, however the PCI that I am using doesn´t have that option..

The version of my Labview is the 8.2 and the NI-Motion is 4.6..

Can someone help me?

You want to adapt a linear drive to a stepper controller card....

You will need some driver circuitry that provide the +/- 5V 550mA for the motor, (H-bridge ) add some additional circuitry to build a servo control with an analog input.

Now use one free digital output (inhibit??)  to create a PWM that is followed by low pass (RC) to feed that anaolg input. 

If you have three free digital outputs you can bit bang a SPI communication that  controll a DA ....

However you will spend a lot of time for that.... a USB 6009 is cheap ...

Hi,

I'll try to get a USB 6009, however this a university project so I do not know if I´ll have money  to buy it...

If not, I´ll try the other solution that you gave me..

Thanks a lot for your time..

Best regards
