8.23.4.7 Enable Switch Link Function
This function is enabled only in the teach mode.
Normally in the teach mode, the servo power is turned ON when the
enable switch is gripped while the servo ON LED on the programming
pendant is flashing. However in this function, when the S-SVON_EN
signal is enabled, the servo power is not turned ON unless the enable
switch is gripped and the S-SVON_EN signal is turned ON.
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 no circuit is configured in the safety logic circuit.
