Incremental encoder output [X11]
The output provides incremental encoder signals that can be processed in superordinate control systems.
The signals are generated based on the angle of rotation of the encoder with a freely programmable line count.
In addition to the track signals A and B, the emulation also provides an index pulse. Once per revolution, this index pulse turns
high (for the programmed number of lines) for ¼ of a signal period (as long as the track signals A and B are high).
