Title:
POSITION CONTROL CIRCUIT FOR SERVO-MOTOR
Document Type and Number:
Japanese Patent JPS62103711
Kind Code:
A
Abstract:
PURPOSE:To perform fast position control over a servo-motor by performing the arithmetic processing of a command count value and a deviation count value not by a microcomputer, but by providing circuits respectively. CONSTITUTION:A pulse signal synchronized with clock pulses is generated from command pulses corresponding to the direction and quantity of movement of a servo-motor 10 from a microcomputer 1 and composite pulses of this pulse signal and position feedback pulses from the motor are counted by counters 6 and 7. Then, those counted values are saturated properly and converted by a digital analog converter 8 into analog signals to drive the servo-motor 10. Consequently, fast operation is possible by performing the servo-motor under the position control of the microcomputer.
