モータ制御回路、モータ駆動制御装置及びモータ駆動制御装置の制御方法
Document Type and Number:
Japanese Patent JP6487879
Kind Code:
B2
Abstract:
A motor control circuit comprising a speed control circuit configured to output speed command information relating to the rotational speed of a motor based on target information relating to a target rotational speed and rotational speed detection information of the rotational speed of the motor, a drive stop control circuit configured to output a first drive stop control signal for performing braking control of the motor or a second drive stop control signal for performing free-run stop control of the motor based on the rotational speed detection information and the speed command information when input of the target information is stopped, and a drive signal generation circuit configured to generate a drive control signal for driving the motor based on the first drive stop control signal or the second drive stop control signal when the first drive stop control signal or the second drive stop control signal is output.
