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 protective functions shown in the following table is activated, terminal So (SO) turns OFF.

If the internal safety circuit is operated normally, terminal So (SO) remains ON until E.SAF is displayed, and terminal So (SO) 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 ON/OFF state of the output signal is the one for the positive logic. The ON and OFF are reversed for the negative logic.
*9
For SAFE signal, refer to the following table and assign the function by Pr. 190 to Pr. 196 (output terminal function selection).

Positive logic
SAFE
*10
The use of SAFE signal has not been certified for compliance with safety standards.
For more details, refer to the Safety Stop Function Instruction Manual. Find a PDF copy of this manual in the CD-ROM enclosed
with the product.
