• Add the terminal to the configuration as described in the section TwinCAT configuration settings –
manual [ } 66] or – Online scan [ } 72].
• Link the terminal with the NC as described in section Integration into the NC configuration [ } 104] (if
TwinCAT NC is used).
• Configure the EL70x7
◦ automatically - import the XML motor file into the startup directory as described in section Set-
tings in the CoE - automatic [ } 105].
◦ manually - configure the parameters as described in section Settings in the CoE - manual
[ } 105].
