Provide a safety circuit outside the programmable controller so that the entire system will opera
safely even when an external power error or programmable controller failure occurs.
Failure to do so may cause an accident due to incorrect output or malfunction.
(1) Outside the programmable controller, create an emergency stop circuit or interlock circuit
prevent mechanical damage due to excess of position control upper limit/lower limit.
(2) The machine OPR control is controlled by the OPR direction and OPR speed data a
deceleration starts when the near-point dog turns ON. Thus, if the OPR direction is incorrec
set, deceleration may not start and the motor continues rotating. Create an interlock circ
outside the programmable controller to prevent mechanical damage.
(3) If the positioning module detects an error, it directs the motor to decelerate and stop.
Make sure that the OPR data and positioning data are within the parameter setting values.
