*1 Do not connect anything to these pins.
*2 A critical error occurs if the input values from the Safety Door 1 and Safety Door 2 are
different for two or more seconds. They must be connected to the same switch with two
sets of contacts.
*3 A critical error occurs if the input values from the Emergency Stop switch contact 1 and
Emergency Stop switch contact 2 are different for two or more seconds. They must be
connected the same switch with two sets of contacts.
