SPEED CONTROLLING METHOD AND APPARATUS OF SERVOMOTOR

摘要

This device controls linearly the acceleration and deceleration of servo motor so that it not only reduces the impact on the motor and controls the speed more precisely but also decrease the control timing. The method comprises the steps of ; inputting a varable correspoding to the acceleration velocity that tells the change of velocity; setting the first detecting unit to detect the clock signals from the oscillation signals generated from the crystal oscillator, a division data corresponding to the acceleration division, and the second detecting unit to detect the up and down counting clock signals; executing the decelerating division due to the control of the micro-processor and the data of the accelerating division; counting the up and down counting clock during the decelerating division; and generating a transmitting pulse by detecting frequency according to the value of counting in the counting period.
