Control device and determination device

A determination device including at least one sub-device that is a power printed circuit board, a power element, a heatsink, a smoothing capacitor, a housing, or a cooling fan and a control device that controls the sub-device, and determining suitability of the sub-device,

• wherein the control device comprises a first processor and an output device including a display device or a voice reproduction device, the first processor being configured to:
• specify a sub-device type of the sub-device;
• select a parameter type of an actual value to be obtained from the sub-device based on the specified sub-device type;
• obtain, as model information, a predetermined value estimated to be output from the sub-device that is suitable, the predetermined value corresponding to the selected parameter type;
• obtain the actual value of the sub-device;
• and
• determine whether the sub-device satisfies a predetermined requirement in accordance with a difference between the obtained actual value and the obtained model information, wherein
• the output device informs an operator that the sub-device is not suitable for the control device to prompt the operator to disconnect the sub-device from the control device in response to a determination result of suitability of the sub-device.
