ABSTRACT:
A motor driving controller that drivingly controls motors for individual axes of an object of control comprises an AC/DC converter circuit for converting AC power into DC power and motor driving DC/AC converter circuits for converting DC power into AC power of optional frequency, for each motor. The controller further comprises an interface through which DC power from the AC/DC converter circuit is delivered to the outside. If motors for peripheral axes are added, motor driving DC/AC conversion devices are added and connected to the interface, whereby DC power is supplied.
