摘要： Position droops produced in main and auxiliary servo motors when main and auxiliary spindles are coupled to each other through a workpiece are obtained by adders, respectively, a difference between those position droops is obtained by a comparator before coupling, a divider divides the position droop difference by the speed of the auxiliary servo motor at the time of detecting the position droop to obtain a position droop difference per a unit speed. Then, after both the spindles are coupled to each other, a multiplier multiplies the position droop difference by the present speed of the auxiliary servo motor, and the adder adds that value to the position command to the auxiliary servo motor. With the above structure, even if coupling is made through the workpiece and synchronization drive is made, an excessive torque can be prevented from occurring, an influence of a change of the change gear ratio with a time is eliminated and a displacement occurring at the time of coupling is corrected.
