Hi all,
I want to control the speed of a three phase motor through a VFD. For the input to the VFD I am using a PLC. Now at present I am using only the digital inputs but I need the variations according to the music. So for the variations I have designed a new circuit which is input to V1 and COM of the VFD. Since I am using a music sensor. After which I use an AC to DC converter to be input to V1 and COM. Now my question is this can I use an analog input or output or input and output module of a PLC instead of this circuit. Becuase I want to get rid of this circuit designing, and since I never use an analog input or output till yet in any of my projects. So curious that how it will work. What about controlling the voltage through the PLC specially in programming? Can anybody explain this to me.
