Operation status at error occurrence
The READY signal [X0] is not turned ON.
When the PLC READY signal [Y0] is turned
from OFF to ON :The READY signal [X0] is
not turned ON.
At start : The system does not start.
During operation : The system stops with the
setting (deceleration
stop/rapid stop) of the
detailed parameter 2 rapid
stop selection
(stop group 3).
(Note that the deceleration
stop only occurs during the
manual pulse generator
operation.)
