Abstract

PURPOSE: To simplify constitution and increase reliability by providing purely electrical upper and lower limiters to the input circuit of a servo system thereby preventing overheating of a motor or deviation amplifier and eliminating the need for limit switches.
CONSTITUTION: Upper and lower limiter circuit LM constituted by a pair of operational amplifiers U2, U3 are provided to the output side of an input circuit IP connected to the front stage of a servo circuit SV. And the output voltage Ep of the input circuit IP is limited to a constant value by this circuit and this limited voltage Ep is applied as an input for the servo system SV. The servo system is so arranged as to follow up its input and therefore even when the limit circuit LM is actuating, the servo system is balanced, hence sustained flowing of a current to a motor M will not occur. Even if any excess input such as overscale or the like is inputted, the motor M or deviation amplifier U or the like will not overheat.
