PROBLEM TO BE SOLVED: To provide a control device for a production apparatus capable of suppressing that a wrong signal is output at activation even when used in an external power supply state.SOLUTION: A control device 10 for a robot comprises: an output part 41 for outputting a power supply voltage to a load 51; an output FET 15 for disconnecting the supply of the power supply voltage to the output part 41; an internal power supply 11 whose level of the power supply voltage to supply is adjusted by the control device 10; and relays 21, 22, and 23 for switching between an internal power supply state in which a power supply voltage of the internal power supply 11 is supplied to the output part 41, and an external power supply state in which a power supply voltage of an external power supply 54 is supplied to the output part 41. The control device 10 is switched over to the internal power supply state by the relays 21, 22, and 23, and then, the power supply voltage of the internal power supply 11 is raised gradually, and thereafter, the control device 10 is switched over to the external power supply state by the relays 21, 22, and 23. |
