Re: Encoder Information Unknown


The am-2816a is listed as 7 "Pulses Per Revolution". Since 7 is an odd number, that must mean 7 cycles per rev, which is 7 rising (or falling) edges per rev per channel, which is 14 rising+falling edges per rev per channel, which is 28 quadrature edges per rev.

So if you decode it at 1x you'll get 7 "counts" per rev, if you decode it at 2x you'll get 14 "counts" per rev, and if you decode it at 4x you'll get 28 "counts" per rev.
