*1 The Emergency Stop condition is output via relay contact when it is open (it is
normally closed).
*2 A critical error occurs if the input values from 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 The signal from the Emergency Stop switch is designed to use two redundant
circuits. An error occurs if the statuses of the two redundant circuits are
different for two or more seconds. They must be connected to the same
switch with two sets of contacts.
