Begrenzerschaltung für Servomotor Steuervorrichtung

摘要

A limiter circuit of servo motor control apparatus which can perform the limiter control in the right or reverse direction or in both directions of a motor, wherein there are provided a microprocessor (5) for outputting switching signal by receiving rotating direction data from a motor rotating direction setter (6), a converter (9) for converting the instantaneous limit value of digital shape outputted from said microprocessor to that of analog shape, a switching portion (8) for selecting the output of instantaneous limit value outputted from said converter, and a limiter (11) for limiting the amplitude of control voltage outputted from PID controller to within the scope of instantaneous limit value selected according to the switching operation of said switching portion.
