Abstract
The invention relates to a method for automatically generating several electrical pulses using numeric default values, in particular for simulating an incremental encoder for a sequential, digital counting of linear or angular displacement values using said pulses. The method incorporates a value generator that outputs the default values repeatedly within each first cycle time, calculation and control means that detect the default values in a cyclic manner and a pulse switching interface that has one or more outputs for the pulses. The program and/or circuitry of the calculation and control means are designed:—for detecting the respective current default value and for determining a differential value from the current and preceding default value or incremental value for each first cycle time, said value having been previously counted in ascending or descending order, according to preceding default values,—for converting the differential value into control signals for the pulse switching interface within several second cycle times, whose total duration does not exceed the first cycle time of the value generator,—and for measuring the number or frequency of the pulse…
