VMA03 without an arduino


#1

hello
i want to use the shield without an arduino. I just want to connect the Motors and give a 5 V ttl on the pin 2.
Does that even work without an arduino


#2

Interfacing with it is a bit more complicated but sure you can do it without an Arduino.
I found this which can help you


#3

Thanks for the quick help.
The problem is that i dont unterstand where i have to connect my wire at the arduino.
i have a 5V Connection at the botton of the shield. Is this the 5V power supply for the IC?


#4

No the 5V comes from the Arduino you’ll have to supply it by yourself


#5

Okay.But from where comes the 5V from the arduino?


#6

From the USB connection or from the DC Jack


#7

Could they use the DC connector and set the jumper to EXT?

High all,

i have also an question about tje VMA03. Is it possible to control a 24V stepper motor with this board? I want to use a 24V 1.8A Siemens LOGO power supply but is it possible?

The specifications off the stepper motor are:

  • Haltemoment: 60 Ncm
  • Strom pro phase: 0.67A
  • Power: 24V
  • Wilerstand pro phase: 5.6 Ohm
  • Inductivitat pro phase: 4.2 mH
  • Tragheidsmoment: 9 gcm²

I didn’t try it but i want to be sure that nothing explode when i connect everything.
What do you think?
