Connection diagram
To prevent restart at fault occurrence, connect terminals So (SO) and SOC to the reset button, which are the feedback input
terminals of the safety relay module.

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, terminal So (SO) and the SAFE output signal turn OFF.


If the internal safety circuit is operated normally, terminal So (SO) and the SAFE output signal remain ON until E.SAF is displayed, and terminal
So (SO) and the SAFE output signal turn OFF when E.SAF is displayed.

SA is displayed when 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 the SAFE signal, refer to the following table and use any of Pr.190 to Pr.196 (output terminal function selection) to assign the function to
the output terminal. 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.
