1.5.2 Incremental Encoder
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. For e.g. the
measuring system outputs a signal sequence of 8192 pulses per revolution.
In order to evaluate the code sequence, a 2nd signal sequence with a 90° phase
offset is output for the control.
The counter of an external control system can be reset with an additional zero pulse in
order to define the mechanical control reference point.
Principle
By a corresponding counter evaluation in the user electronics the measuring system
resolution can be doubled or quadrupled electronically:
