[Design Precautions]
WARNING
● Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable
controller. Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be
configured external to the programmable controller.
(2) Machine OPR (Original Point Return) of the positioning function is controlled by two kinds of
data: an OPR direction and an OPR speed. Deceleration starts when the near-point watchdog
signal turns on. If an incorrect OPR direction is set, motion control may continue without
deceleration. To prevent machine damage caused by this, configure an interlock circuit external
to the programmable controller.
(3) When the CPU module detects an error during control by the positioning function, the motion
slows down and stops.
