INSTALLATION AND WIRING
Safety stop function operation
 ON: The transistor is conducted. OFF: The transistor 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 faults shown in the following table occurs, terminal So (SO) and the SAFE signal turns OFF.
 When the internal safety circuit is operated normally (no faults occurs), terminal So (SO) and the SAFE signal remain ON until "E.SAF" is
displayed. Terminal So (SO) and the SAFE 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.
 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.
 To assign the function of the SAFE signal to an output terminal, set either value shown in the following table in any of Pr.190 to Pr.196 (Output
terminal function selection).
 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. (A PDF copy can be found in the enclosed CD-ROM.
For how to use this CD-ROM, refer to page 146.)
