PROBLEM TO BE SOLVED: To prevent an error that has occurred to a sub control unit from being reset illegally.SOLUTION: When an error in a first sub control part 400 occurs and press operation of a reset switch 290 is performed, an up edge signal of operation start is transmitted to a first sub control unit 400 as a first error reset command, and a down edge signal of operation completion when a reset switch 290 is released is transmitted to the first sub control unit 400 as a second error reset command. By turning a reset operation monitoring flag on on the basis of a command related to the up edge signal, reset reception of sub errors is started. When a command related to a down edge in the state that the reset operation monitoring flag is on is not received, a sub error state is continued without resetting the sub error. |
