An object of the present invention is to provide a servo motor driving apparatus and a servo motor driving method for driving a plurality of servo motors, wherein provisions are made to improve the reuse efficiency of servo motor regenerative energy. The servo motor driving apparatus (2) comprises: a plurality of inverter circuits (4, 4', 4") which supply AC power to the plurality of servo motors (5, 5', 5"), respectively; a converter circuit (3) which supplies electric power in common to the inverter circuits (4, 4', 4"); and an inverter control unit (6) which, when giving an acceleration command to any one of the servo motors, gives a deceleration command to another one of the servo motors at the same time. |
