*1 The terminal ON state shows that the terminal is conducted (the line is closed), and the OFF state shows that the terminal is not conducted (the
line is open).
*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 protective functions shown in the following table is activated, terminal So (SO) and the SAFE signal turn OFF.

*4 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 a fault occurred in the internal safety circuit.
*6 If another fault occurs when the fault E.SAF occurs, the other fault indication may be displayed.
