Hi all,
Its been a long time since I have written into this discussion forum. I have a question. Till now I have been using encoder as a feedback device for position control in PCI 7342 motion controller. Now I want to know about position control using the analog input channel. I cant figure out how the controller understands the equation between input voltage and position.
Say X Volts = How many mm of movement?
With the encoder f/b the motion controller knows the encoder pulse per revolution and it keeps counting the feedback and generates motion accordingly. How is it done with analog feedback. My application involves an LVDT which give proportional analog feedback with respect to the displacement. Please help me oiut on this. Also is position compare and breakpoint feature relevant to this particular problem?
