5.4 Pin Assignments

The EMERGENCY connector pin assignments are as follows:
Pin No.
*1 The Emergency Stop condition is output via relay contact when it is open (it is
*2 A critical error occurs if the input values from the Safety Door 1 and Safety Door 2
*3 The signal from the Emergency Stop switch is designed to use two redundant circuits.
