*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.
*4 Do not apply reverse voltage to the Emergency Stop circuit.
