Servomotor control method for driving machine tool, involves correcting torque according to distance from position where moving direction of machine is changed with respect to torque command value at time of quadrant switching

摘要

The method involves detecting a position of a machine directly or indirectly, when the moving direction of the machine is changed. Torque correction is performed according to a distance from the position where the moving direction of the machine is changed with respect to torque command value at the time of quadrant switching.
