Abstract
A method for decelerating a motor in a computer numerical controlled machine tool is provided. The method includes calculating a present rate of deceleration D, for a motor of a motor drive system, based on a present speed Sof the motor, a reference speed Sof the motor, and a reference rate of deceleration Dof the motor. The method also includes decelerating the motor from Saccording to D. The motor drive system comprises a maximum power rating that defines a maximum power, generated by the motor while decelerating, that can be dissipated without overloading the motor drive system. Dis a rate of deceleration such that power, generated by the motor while decelerating from Saccording to D, is equal to the maximum power rating. Power, generated while decelerating the motor from Saccording to D, is equal to or less than the maximum power rating.
