*3 If any of the faults shown in the following table occurs, terminal SO, the SAFE signal, and the SAFE2 signal are turned OFF.
Fault type
Option Fault
Communication option error
Parameter storage device fault (control
circuit board)
Retry count excess
Parameter storage device fault (main
circuit board)
Safety circuit fault
*4 When the internal safety circuit is operated normally (no fault occurs), terminal SO, the SAFE signal, and the SAFE2 signal remain ON until
"E.SAF" is displayed. Terminal SO, the SAFE signal, and the SAFE2 signal are turned OFF when "E.SAF" is displayed.
*5 "SA" is displayed when terminals S1 and S2 are identified as OFF due to the internal safety circuit failure.
*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. In negative logic, the signal status is opposite.
*9 To assign the functions of the SAFE signal and SAFE2 signal to output terminals, set values shown in the following table in any two parameters
from Pr.190 to Pr.196 (Output terminal function selection).
Output signal
SAFE
SAFE2
*10 The use of the SAFE signal and SAFE2 signal has not been certified for compliance with safety standards.
For details, refer to the FR-E800 Instruction Manual (Functional Safety).
