10-2-1 Monitoring EtherCAT Communications and Turning ON Servos

In this sample, the MC_Power (Power Servo) instruction is executed to turn ON the Servo for the Servo
Drive when EtherCAT process data communications are established with the Servo Drive.
Samples are provided for both ladder diagram and ST programming.

Comment
This is the Axis Variable for axis 0.
TRUE when there is a minor fault level error for
axis 0.
This is the node address.
TRUE when EtherCAT process data communi-
cations for node address N are in Operational
state.
When StartPg is TRUE, the Servo is turned ON
if EtherCAT process data communications are
active and normal.
