System Setup
9 - 302
4. The following safety logic circuit is created.
01 SFBIN01 #1 S-ONEN1
5. When #1 S-ONEN1 is turned ON, the SERVO power of R1 is turned OFF.
The message “SERVO ON enable signal (ON-EN) is OFF (Safety logic circuit)” is
shown on the message area of the programming pendant.
NOTICE
If the hard-wired ON_ENABLE signal and #n S-ONEN[x] signal of the safety logic circuit
are used, the SERVO is turned ON only when the status of both signals is not the
SERVO OFF. When the status of either signal or both signals is the SERVO OFF, the
servo is not turned ON for the control group allocated to the ON_ENABLE signal.
For details of the SERVO power individual control function, refer to „INSTRUCTIONS
FOR INDEPENDENT/COORDINATED CONTROL FUNCTION“ manual in chapter
„SERVO Power Individual Control Function”.
<The safety logic circuit: example 8>
In the following example, the specific input signal is output to the safety PLC (optional). The
logic circuit to output the specific input1 (#40780) to the safety PLC is created.
1. Select {SAFETY SIGNAL ALLOC} from {SAFETY FUNC.}.
Set ASF01-E to SFBOUT01
2. The following safety logic circuit is created.
01 SPIN01 SFBOUT1.
3. When #40780 is turned OFF, SFBOUT01 is also turned OFF.
When #40780 is turned ON, SFBOUT01 is turned ON.
