I have a closed system with a DC motor and a single-channel incremental encoder for position feedback. I bought a controller that says it takes dual channel (quadrature) encoder input (channels A, B). I do not need the directional elements of the device (the reason for the 2nd channel), but would like to still find a way to interface the system with the controller. Is there a way I can emulate a quadrature signal by feeding the system signal through something to shift its phase 90 degrees? Is that even necessary?
Thanks!
