Abstract

PURPOSE: To supply a servo unit, which is used in the positioning unit of the all digital system, in a simple constitution by utilizing a general micro processor.
CONSTITUTION: Interruption signal IRT2 is given each time a set input signal is given to input terminal 1 or 2, and micro processor 11 stores position information NIN where a moving object should be set. Interruption signal IRT3 is given each time a feedback pulse is given to input terminal 3 or 4, and micro processor 11 stores position information NFD of the moving object. When timer 13 generates interruption signal IRT1 at every prescribed period, micro processor 11 calculates Pw=α(NIN-NFD-A) [α: time conversion coefficient, A: feedback correction quantity] and gives a pulse train, which is subjected to pulse width modulation according to Pw, to DC motor 6.
