Bus configuration.
Element connection.
Use an inline topology. Join the B64 connector of the CNC to the X1(IN) connector of the
first header. Connect the other of headers, joining the X2 (OUT) connector of one header
with the X1 (IN) connector of the following one. Do not connect the X2(OUT) connector of
the last header.
In order to ensure proper performance, the connection cable must be inserted all the way
into the connectors so they're latched. This ensures that the cable is properly latched and
does not come off due to vibration.
Module identification.
The node number for each header is not defined on this bus. The node number is assigned
by the configurator on the basis of its designed topology.
Transmission speed.
The transmission speed is 100 MHz. Use a cable having the recommended characteristics
to ensure this speed.
Activate the bus on the CNC.
Activate the bus on the CNC using the machine parameter ETHERCATBUS.
Configuring the EtherCAT bus.
Fagor supplies the configurator “KPA EtherCAT Studio” (by Koening-pa GmbH) under
license, which can operate both online and offline, to define the bus topology and create the
ENI file containing the bus device information. This file must be copied to the folder
../Mtb/Data of the CNC with the name "fagor_ethercatConfFile.xml". This file also uses the
"Fagor EtherCAT Mapper" program for determining the resources available in the bus.
