Used to stop the robot motion from the external equipment. 
The robot slows down and stops at the same time that this 
signal is open.    After the stop, the robot enters a STOP 
(RETRY) status. 
Even if this signal is short-circuited again after the stop of 
robot motion, the robot will not operate.    To restart the robot, 
short-circuit this signal, then execute the RUN command. 
If this signal is open, the robot cannot be started. 
This signal can always be used, irrespective of the master 
mode selected by means of the MODE switch. 
*1  Duration from the start of one motion command to just 
before the start of next motion command is called "1 
segment". 
1.  If the robot is operating, processing of execution is 
interrupted and the robot slows down and stops. 
2.  Unless this signal is used, short-circuit the INPUT-32 
signal according to the common wire connection.
