Fig. 130: Figure 17-4
STO, Pr.06-44=0, Pr.02-35=0
(external operation control selection after reset / reboot, 0=disable)
As shown in the figure below, when both S1–DCM and S2–DCM are OFF during operation (STO function is
required), the drive stops outputting when it enters safe mode regardless of whether the RUN command is in ON or
OFF status.
Figure 17-5
STO, Pr.06-44=0, Pr.02-35=1
(external operation control selection after reset / reboot, 1= drive runs if the RUN command remains after
reset or reboot)
As shown in the figure below, the action is the same as in the figure above; however, because Pr.02-35=1, if the
RUN command remains after reset, the drive immediately executes the RUN command again.
