*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.
