  • ENCODER PROVIDING ERROR DETECTION
    Publication number: 20200394479
    Abstract: Movement detection circuitry is provided for a moveable component of an apparatus having an encoder member having a plurality of spaced regions to cause a response by a first detector and a second detector on the moveable component. First and second detection signal detection signals are received respectively from the first detector and second detector by processing circuitry of the movement detection circuitry. At least one of the first detection signal and the second detection signal is sampled when the first detector and second detector move relative to the encoder member. An error due to any impairment to one the spaced regions of the encoder member is based upon a comparison between the samples from the two detectors. A movement characteristic of the moveable component is determined by the processing circuitry from at least one of the first detector samples and the second detector samples.
