 Pr.04-10=0: STO fault latched, resending RUN command is required. If STO is ON in any
condition and a fault occurs, it does not reset until STO is back to normal and use a RESET
command or power-on again after resending the RUN command.
 Pr.04-10=1: STO warning latched, resending RUN command is required. If STO is ON in any
condition and a warning occurs, it does not reset until STO is back to normal and resend the
RUN command.
 Pr.04-10=2: STO fault latched. If STO is ON in any condition and a fault occurs, it does not reset
until STO is back to normal and use a RESET command or power-on again.
 Pr.04-10=3: STO warning unlatched. If STO is ON in any condition and a warning occurs, it
automatically resets when STO is back to normal.
 Pr.04-10=4 / 5 / 6 / 7: When FWD/REV command is ON and STO circuit is OFF for more than
10 ms, and when Pr.00-03=1 and Pr.04-13=1, STO will be OFF and then Stob warning occurs.
When FWD/REV command is OFF and STO circuit is ON, Stob warning will be automatically
cleared. Once Stob warning is cleared, the drive starts to run when FWD/REV command and
STO circuit are both ON. When Pr.00-03=2 / 3 / 6 and Pr.04-13=1, Stod fault occurs. Stod fault
can be reset only when RUN command is removed. If there is no warning or fault that
specifically requires to give RUN command again, the drive normally will start to run when
FWD/REV command and STO circuit are both ON after warning/fault is cleared.
 Pr.04-10=4 / 5 / 6 / 7: If STO circuit is OFF while drive outputs, STO circuit will be OFF in
advance and then Stor fault occurs. This fault will be automatically cleared after 5 seconds.
