ABSTRACT:
A limiter circuit of a servo motor control apparatus can perform limiter control in the right direction or reverse, direction or in both directions of a motor therefore. There is provided a microprocessor for outputting a switching signal by receiving rotating direction data from a motor rotating direction setter, and a converter for digital to analog converting the instantaneous limit value outputted from the microprocessor. Also included is a switching portion for selecting the output of instantaneous limit value outputted from the converter, and a limiter for limiting the amplitude the control voltage outputted the PID controller to within the scope of the instantaneous limit value selected according to the switching operation of the switching portion.
