Hey guys,
I need help with a project for school. I want to control a variable frequency drive using the Arduino platform in order to cut costs. I have found lots of conflicting information and was hoping somebody here could help out.
I know that I likely need to step the voltage up to 10v to interface with the VFD, but I'm not sure what component I need for that. Or do I even need extra components?
I do not know what motor I will use yet, nor which VFD.
I will provide any information that you guys need.
Thanks in advance for any help!
Ducky
Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.

What VSD will you be getting?
Can you post a link to your VSD please?
What Arduino will you be using?
Most Arduinos have PWM output that can be filtered to provide an analog output.
Or a DtoA output that can be amplified to 0 to 10V.
Some VFDs will accept PWM input for speed control, converting 5V or 3.3V logic from a controller can also be done with minimum of components.
What course is this for and what is the overall project?
Can you tell us your electronics, programming, Arduino, hardware experience?
Thanks.. Tom..
