• Example of use of the enable switch link function
The following is an example of using the optional safety PLC.
1. The enable switch signal on the programming pendant and the TEACH mode
information are output to the safety PLC by the safety logic circuit. The value output
from the safety PLC is input in the S-SVON_EN signal of the safety logic circuit.
2. When the S-SVON_EN signal is turned ON, the SERVO power is ON and when the
enable switch is released, the signal is OFF.
The SERVO ON/OFF status when the SERVO ON Enable (S-SVON_EN) signal is
enabled
*Note: Not Used means the S-EXDSW signal is not used as the output signal of the
safety logic circuit.

NOTICE
 When this function is enabled, configure the circuit of the safety PLC (optional) to turn
OFF the servo ON enable signal (S-SVON_EN) by releasing the Enable Switch of the
programming pendant.
