Operation of the SAFE and SAFE2 signals
*1
If any of the faults shown in the following table occurs, the SAFE signal and the SAFE2 signal are turned OFF.
*2
When safety communication functions are enabled ( Pr.S002 ≠ "0"), the STO function is enabled while the safety communication is not
established.
*3
If another fault occurs when the fault E.SAF occurs, the other fault indication may be displayed.
*4
If another warning occurs when the warning SA occurs, the other warning indication may be displayed.
*5
The ON/OFF state of the output signal is the one for the positive logic. In negative logic, the signal status is opposite.
*6
To assign the functions of the SAFE signal and SAFE2 signal to output terminals, set either value shown in the following table in
Pr.192 ABC terminal function selection . To output the signal via communication, the function can be assigned also to Pr.190 to
Pr.196 (Output terminal function selection) using communication protocols. For details, refer to the Instruction Manual
(Communication) or the Instruction Manual of each communication option.
*7
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-SCE Instruction Manual (Functional Safety).
