Incremental encoder output [X11]
The output provides incremental encoder signals for processing in superimposed controls.
The signals are generated from the encoder’s angle of rotation with a freely programmable number of lines.
Besides the encoder signals A and B, the emulation also provides a reset pulse, which goes to high once per rotation (for the
programmed number of lines), for the duration of a ¼ signal period (as long as the encoder signals A and B are high).
