I want to use computer to control the stepping motor(model: PK264-02A ,VEXTA, 2-phase, DC 2A 1.4 ohm). Now I have USB-6525 and USB-6501. I tried to connect the stepping motor, USB-6525 and a power supply. Here is how I connected the wires.
USB 6525 Input
(2-20)VDC ---- USB P1.0 +
ground ------- USB P1.0 -
USB 6525 Output( stepping motor has six wires)
Phase A common (white) & Phase B common (Yellow) ----- USB P0.0A
Phase A (Red) ------USB P 0.1A
Phase A\ (Blue) -----USB P0.1B
Phase B (Green) -----USB P0.2A
Phase B (Black) ------USB P0.2 B
BUT, I use MAX and SingalExpress to test, there seems no signal.
My question is (1)whether my connection is wrong or I need some other driver to control the motor ?
(2)Do I have to write vi file to control stepping motor?
(3)What's the function of USB 6525 here if I need another driver?
(4) Does the current matters? The USB-6525 has 500mA max current per channel but the motor ask for 2A maybe.
