摘要:
A drive control device is provided with a physical amount detection unit which detects the physical amount pertaining to the output of a motor, a rotational frequency determination unit for determining whether the rotational frequency of the motor is equal to or greater than a base rotational frequency, a threshold value selection unit for selecting a threshold value for the physical amount in accordance with the determination result of the rotational frequency determination unit, and a rotational frequency control unit for controlling the rotational frequency of a rotating shaft in accordance with the magnitude relationship between the detected physical amount and the selected threshold value.
