Document Type and Number:
Japanese Patent JP2559279
Kind Code:
B2
Abstract:
In a method for performing a synchronized superposed operation of two servomotors, controllers for the servomotors perform the control for achieving the synchronized superposed operation by: calculating, for each of the servomotors, the difference, or differences, between the ideal droop, or droops, obtained from a control command and the actual droop, or droops, obtained from the rotation of the servomotor; calculating a speed correction quantity, or the speed correction quantity and a current correction quantity, from the discrepancy, or discrepancies, between the differences calculated for both of the servomotors; and adding the correction quantity, or quantities, to a speed command, or the speed command and a current command, given to the side of the subsidiary shaft. Thus, a synchronized superposed operation of servomotors in which speeds and responses of the main shaft and the subsidiary shaft are well balanced therebetween can be achieved.
