| 摘要 | PURPOSE: To control the rotary speed of a motor accurately by processing a monitor signal, generating a comparison value for comparing it with a value corresponding a signal from a signal transmitting means, and correcting a digital output signal, when the two values do not match. CONSTITUTION: A motor drives a shaft encoder E, and the encoder E sends a pulse train consisting of signals that indicate the actual rotary speed of a shaft to a central processing device(CPU). The signal is compared with a corresponding value that indicates a desired rotary speed and is adjusted, as needed, by processing a digital input signal to be sent to a processor before a control signal is sent to an inverter I, thus correcting the mismatch between the desired and actual rotary speeds of a drive shaft, thus obtaining a closed loop system that positively associates the output rotary speed of the motor to the desired speed.
