Title:
CONTROLLER OF MOTOR
Document Type and Number:
Japanese Patent JPS6035987
Kind Code:
A
Abstract:
PURPOSE:To accurately perform a PLL control in a wide range with a simple configuration by utilizing a counter in a microcomputer and controlling a regulator by the microcomputer. CONSTITUTION:The first counter 3A generates a reference frequency signal FS in accordance with a motor speed command from ten keys 1, and the second counter 3B generates a speed control signal FV synchronously with a feedback signal FG from an encoder 12. A phase comparator 5 outputs a phase comparison signal PC between the signals FS and FG. The signals FV and PC are added by an adder 8, converted by a comparator 9 to a pulse width modulation signal, and supplied to a driver 10. A microcomputer 3 varies the electronic volumes 13-16 when the phase difference is not locked, and regulates them.
