After power supply from a backup power source to a volatile memory is restored from temporary suspension, a remaining data determining section determines whether data of change history remaining in the volatile memory is data that has been stored immediately before the suspension of the power supply. When it is determined that the data remaining in the volatile memory is not the data that has been stored immediately before suspension of the power supply, a reference value learning section moves an actuator to a limit position, assigns the reference value to an initial value, and clears the change history. When suspension of the power supply from the backup power source reoccurs before completion of the reference value learning by the reference value learning section, a control section invalidates the determination of the remaining data determining section and performs the reference value learning, after the power supply is restored.
