*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 faults shown in the following table occurs, terminal So (SO) and the SAFE signal turn OFF. When a fault occurs in parallel operated
inverters, only the inverters in which the protective function is activated stop the output of the SAFE signal.
Fault type
Option fault
Communication option fault
Parameter storage device fault
(control circuit board)
Parameter storage device fault
(main circuit board)
Operation panel power supply
short circuit/RS-485 terminals
power supply short circuit
24 VDC power fault
Safety circuit fault
*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.
*7
If another warning occurs when the warning SA occurs, the other warning indication may 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
To assign the function of the SAFE signal to an output terminal, set either value shown in the following table in any parameter from Pr.190 to
Pr.196 (Output terminal function selection).
Output signal
SAFE
*10 The use of SAFE signal has not been certified for compliance with safety standards.
