Incremental encoder coding！
Changchun Rongde Optics Co.,Ltd. Release time：2016/10/9 Browse：746Incremental encoders provide a specific number of equally spaced pulse per revolution or per inch or millimeter of linear motion.A single channel output is used
for applications where sensing the direction of movement is not important. Where
direction sensing is required, quadrature output is used, with two channels 90 elec
trical degrees out of phase; circuitry determines direction of movement based on the phase relationship between them. This is useful for processes that can reverse, orexample, machine vibration while stopped could cause a unidirectional encoder to produce a stream of pulses that would be erroneously counted as motion. The controller would not be fooled when quadrature counting is used.
When more resolution is needed, it’s possible for the counter to count the leading
When more resolution is needed, it’s possible for the counter to count the leading
and trailing edges of the pulse train from one channel, which doubles (×2) the num
ber of pulses counted for one rotation or inch of motion. Counting both leading and
trailing edges of both channels will give 4× resolution.
