whole system will operate safely even if an external power failure or a 
programmable controller failure occurs.
Otherwise, incorrect output or malfunction may cause an accident.
(1) For an emergency stop circuit, protection circuit and interlock circuit that 
is designed for incompatible actions such as forward/reverse rotation or 
for damage prevention such as the upper/lower limit setting in 
positioning, any of them must be created outside the programmable 
controller.
Install the emergency stop switch outside the controlpanel so that 
workers can operate it easily.
