Download the configuration to the master.
After downloading the configuration to the master the LED(s) on the front of the SM-
EtherCAT should flash, depending on the port(s) connected.
Values written to parameters over RxPDOs should now be viewable using the drive’s
keypad so long as the master has put the slave into the Operational state; also,
parameter values changed using the drive keypad will be updated on the master.
