17-6-2-2 STO, Pr. 06-44=0, Pr. 02-35=1 (Selection of external control operation after
reset / power on, 1= the drive will execute RUN if command exists after reset)
As shown in Figure 6, the action is the same as in Figure 5. However, because Pr. 02-35=1,
if RUN command still exists after reset, the drive will execute run command again
immediately.

As shown in Figure 7: When both of S1~DCM and S2~DCM are OFF during operation (STO
function is required), the drive will stop outputting. When the S1 / S2 status is restored (ON),
the STO automatic alarm is automatically cleared. The drive can output when RUN command
is released again.
