Title:
MOTOR CONTROLLER AND STORAGE MEDIUM
Document Type and Number:
Japanese Patent JP3800917
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor controller capable of smoothly stopping a motor in terms of motor deceleration. SOLUTION: The motor controller controls the speed of the motor M, based on the feedback information (encoder signal) from the motor. If the pulse width of an encoder signal is prolonged during the deceleration of the motor by pulse width modulation according to the encoder signal and a timeout occurs, CPU 1 judges this as being excessive deceleration and slightly increases the motor speed.
