[DESIGN PRECAUTIONS]
DANGER
Create a safety circuit outside the programmable controller to ensure the
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 outsid the controlpanel so that workers
can operate it easily.
