Re: [CAD_CAM_EDM_DRO] Quadrature?

Hi,

The word gives it away. Quad means four. So your 10,000 pulse encoder is
really a 2500 line with the pick-ups translating this into quatrature it
equals the 10,000 pulses. Notice I have used the words lines and pulses.
There is also two outputs from then encoder an A and B channel.

dro?
