Abstract:
A process for automatic generation of several electrical pulses using numerical default values for simulating an incremental encoder for sequential digital counting of linear and angular displacement values using the pulses, with a value generator which outputs the default values repeatedly within each first cycle time, with calculation and control means cyclically detecting the default values and with a pulse switching interface controlled thereby which has one or more outputs for the pulses, the calculation and control means performing the process steps comprising:(a) detecting a current default value and determining a difference value from the current and a previous default value or an incremental value per first cycle time, which value has been counted upwards or downwards according to previous default values; (b) converting the difference value into control signals for the pulse switching interface within several second cycle times, the total duration of which does not exceed the first cycle time of the value generator; and (c) dimensioning the number or frequency of the pulses or pulse flanks to be output per first cycle time according to the difference value concerned.
