1. A control device comprising:
a first control substrate including a processor and a communication interface; and
a second control substrate including a processor and a communication interface,
wherein the first control substrate and the second control substrate are connected through the communication interfaces, and
wherein when occurrence of an error in data communication through the communication interfaces is detected, at least one of the processor of the first control substrate and the processor of the second control substrate performs the data communication using unused signal lines among signal lines provided in the communication interfaces, and
the unused signal lines are low-speed signal lines that are never used during normal operation without an error and that perform a limited operation than a signal line in which the error occurred in the communication interfaces.
