A single driving system (4, 5, 6) is provided for a plurality of pairs of controlled systems and axis controllers (1, 12:2, 13). This driving system is connected to a required pair of the controlled systems and the axis controllers as needed using an axis changing device (3) and a changing controller (7). At this time, the shaft position data of the driving system, at the time when a controlled system is separated from the driving system, is stored in a first axis shaft position data storing device (8) or a second axis shaft position data storing device (11). When the connection is returned, an offset signal is sent to the changing controller (7) from a first axis shaft position offset calculator (9) or a second axis shaft position offset calculator (10). Thus, a plurality of controlled systems can be driven by a single driving system.
