This interface module uses the position information in a dual channel quadrature encoder to remove spurious counts caused by mechanical vibration. Logic gates in the Anti-Dither Module use the quadrature relationship to discriminate between dithering and actual movement. Using this quadrature relationship of the data, a signal is created with +/- 1/4 cycle of hysteresis. The index pulse from the encoder is optically isolated and passed directly to the controller for use as a reference.
