5.2 Data transmission
Angular increments are recorded via a pulse disk with a fixed number of cycles per
revolution. A scanning unit with an integrated optoelectronic system generates
electrical signals and emits pulses (measuring increments) which are pre-processed
at trigger stages.
The resolution of the measuring system is defined via the number of light/dark
segments (number of increments per revolution) on the pulse disk. At the standard
version for e.g. the measuring system outputs a signal sequence of 1024 pulses while
completing a single revolution. In order to evaluate the code sequence, a 2
nd
signal
sequence with a 90° phase offset is output for the control.
The counter of an external control system can be reset with the additional zero pulse
in order to define the mechanical control reference point.
