∗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 protective functions shown in the following table is activated, the terminal So (SO) and the SAFE output signal
turns OFF.

∗4 When the internal safety circuit is operated normally, the terminal So (SO) and the SAFE output signal remain ON until E.SAF
is displayed, and the terminal So (SO) and the SAFE output signal turn OFF when E.SAF is displayed.
∗5 SA is displayed when the 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 For the SAFE signal, refer to the following table and assign the function using Pr.190 to Pr.196 (output terminal function
selection). 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.
SAFE
∗9 The use of SAFE signal has not been certified for compliance with safety standards.
NOTE
• The response time from safety stop signal input to drive shutoff (safe state) is faster than 8ms.
• Hold the ON or OFF status for 2 ms or longer to input signal to terminal S1 or S2.
Signal input shorter than 2 ms is not recognized.
