Tab. 2-27:
ON: Transistor used for an open collector output is conducted.
OFF: Transistor used for an open collector output is not conducted.
When not using the safety stop function, short across terminals S1 and PC, S2 and PC, and SIC and
SD to use the inverter. (In the initial status, terminals S1 and PC, S2 and PC, and SIC and SD are
respectively shorted with shorting wires.)
If any of the protective functions shown in the following table is activated, the terminal SO turns
OFF.

Tab. 2-28:
If the internal safety circuit is operated normally, the terminal SO remains ON until E.SAF is
displayed, and the terminal SO turns OFF when E.SAF is displayed.
SA is displayed when the terminals S1 and S2 are identified as OFF due to the internal safety circuit
failure.
If another fault occurs at the same time as E.SAF, the other fault can be displayed.
If another warning occurs at the same time as SA, the other warning can be displayed.
For more details, refer to the Safety stop function instruction manual (BCN-A23228-001).
