∗1 ON: The transistor is conducted. OFF: The transistor is not conducted.
∗2 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.)
∗3 If any of the faults shown in the following table occurs, terminal So (SO) and the SAFE signal turn OFF.

When the internal safety circuit is operated normally (no faults occurs), terminal So (SO) and the SAFE signal remains ON until "E.SAF" is
displayed. Terminal So (SO) and the SAFE signal turns OFF when "E.SAF" is displayed.
∗5
SA is displayed when terminals S1 and S2 are identified as OFF due to the internal safety circuit failure.
∗6
If another fault occurs at the same time as E.SAF, the other fault can be displayed.
∗7
If another warning occurs at the same time as SA, the other warning can be displayed.
∗8
The table shows the signal status in positive logic. In negative logic, the signal status is opposite.
∗9
For SAFE signal, refer to the following table and assign the function by Pr.190 to Pr.196 (output terminal function selection).

∗10 The use of SAFE signal has not been certified for compliance with safety standards.
