stepper motor/labview/USB-6002

[jietucs]

Hello!

Now, I have Data Acquisition Card USB-6002. I want to use this to control the stepper motor. It seems that the voltage from USB-6002 is not high enough for stepper motor. Should I buy a stepper motor driver, or is is possible to connect steper motor driver with USB-6002？ Or I should use voltage amplifier connected to USB-6002 without stepper driver?

Hi jietucs,

It seems that the voltage from USB-6002 is not high enough for stepper motor.

Yes. But even more the current from the AO pins is not high enough…

Should I buy a stepper motor driver

Yes, sure.

or is is possible to connect steper motor driver with USB-6002？

Surely you can connect the motor directyl to your DAQ device - but without any useful results… (Sarcasm!)

Or I should use voltage amplifier connected to USB-6002 without stepper driver?

Use a stepper motor driver, they are made for just that purpose…

(To put that in other words: you aren't able to read the datasheets of the USB6002 and your stepper motor, but you want to use some "self-built" amplifier circuits?)

Hi,

Can I see your vi code ?

Hi Saad,

who is "you" and which "code" are you talking about?

Hi,

I am working in my lab to run a 4-wires stepper motor (12V ) for my project, this stepper motor is moving a tray on a linear rack . 

I am using DAQ 6002 and driver 8825.

I need the code that can do the things above !

Hi Saad,

After a quick internet search I guess all you need are two digital signals to set "STEP" and "DIR" (read the 8825 manual for more details). The USB6002 provides those digital output signals.

All you need is a little VI setting the DO signals as needed - see all those DAQmx example VIs coming with LabVIEW for inspiration…

(When you "need the code" you should start creating it using LabVIEW.)

Thank you very much .

Thank you very much for your reply.

Now, I have a step motor 28BYJ-48 with an driver board. I also have a DC power source suitable for this step motor. Actually, the key component of this driver board is ULN2003. It seems that this driver board is made for Arduino control, yes or no? Can I use the TTL signal from USB-6002 to connect with this driver board,and finally control the step motor?

Hi jietucs,

Read the manual of that driver board to find the answer…

Yes.

(Again: the answer to this question could be found be reading the manual of that ULN2003 IC…)

thank you for you quick answer. I have no such experimence before, so I want to make sure that it will work before I start.
