A control device includes a program analysis unit, a program execution unit, and a servo control unit. The program analysis unit includes a machining/non-machining state determination unit that determines whether a target block of a machining program is in a machining state or a non-machining state, a switching necessity determination unit that determines whether it is necessary to perform switching of a control target axis of the target block and/or switching of an electrical current control cycle, and an information adding unit that adds a switching request and information after switching to an analysis result of the target block. The program execution unit includes a switching execution unit that executes the switching of the control target axis of the target block and/or the switching of the electrical current control cycle. The servo control unit controls the control target axis at the switched electrical current control cycle.
