Auto
Set the operation cycle of motion
control.
Operation at STOP to RUN
M2000 is turned on by switching
from STOP to RUN./M2000 is
turned on by switching from STOP
to RUN and setting 1 in the set
register.
M2000 is turned on by
switching from STOP to
RUN.
Set the condition in which the PLC
ready flag (M2000) turns on.
Forced stop (Note-1)
None/X(PX) (0 to 1FFF)/
M (0 to 8191)
None
Set the bit device to use forced stop
in the program.
However, the forced stop input by

(empty) for slots 0/1/2. (The setting
range varies depending on the
number of Multiple CPUs installed.)
None
Set the installation position of the
self CPU in the main base.
