How is the encoder output frequency specified?

The output clock frequency determines the maximum frequency of A/B channel transitions. It is expressed in megastates/sec or counts/sec.

The frequency should be chosen to be equal or less than equal to the maximum input frequency of the receving electronics. Note that if the speed is such that the selected frequency is exceeded, the encoder will buffer the excess counts.

Should motion suddenly stop the encoder will operate in burst mode emptying the buffer. This situation should be avoided when the encoder is part of a servo loop.
