Integration of EtherCAT plug-in modules in the NC configuration

(Master: TwinCAT 2.11 R3)

Installation of the latest XML device description

Please ensure that you have installed the corresponding latest XML device description in TwinCAT. This can be downloaded from the Beckhoff Website and installed according to the installation instructions.

Requirements for the integration in the NC:

The TwinCAT NC can only be used for the CSP and CSV operation modes.
The module must already be installed under I/O devices

manually inserted
(see EtherCAT system documentation "OFFLINE Creation of the configuration") or
have been scanned by the system
(see EtherCAT system documentation "ONLINE Creation of the configuration").

Adding an axis automatically

TwinCAT detects the new axes automatically once the modules have been successfully scanned. The user is asked whether the detected axes should be added
automatically (see Fig. Axis detected). If this is confirmed, all axes are automatically liked to the NC.

Integration of EtherCAT plug-in modules in the NC configuration 2: — Axis detected

Several parameters have to be set before the motor can be started up. See chapter "Configuration of the TwinCAT NC".
Please set these parameters before continuing with the motor commissioning procedure.

Adding an axis manually

First add a new task. Right-click on NC Configuration and select "Append Task..." (see Fig. Adding a new task).
Rename the task if required and confirm with OK.

Integration of EtherCAT plug-in modules in the NC configuration 3: — Adding a new task

Right-click on Axes, then add a new axis (see Fig. Adding a new axis).

Integration of EtherCAT plug-in modules in the NC configuration 4: — Adding a new axis

Select Continuous Axis type and confirm with OK (see fig. Selecting and confirming the axis type).

Integration of EtherCAT plug-in modules in the NC configuration 5: — Selecting and confirming the axis type

Left-click your axis to select it. Under the Settings tab select "Linked to..." (see fig. Linking the axis to the module).

Integration of EtherCAT plug-in modules in the NC configuration 6: — Linking the axis to the module

Select the right module (e.g. Stepper Drive (MDP 703)) and confirm with "OK".

Integration of EtherCAT plug-in modules in the NC configuration 7: — Selection of the correct module using the EJ7047 module as an example

All main links between the NC configuration and the module are set automatically (see figure below)

Integration of EtherCAT plug-in modules in the NC configuration 8: — Automatic linking of all important variables using the example of the EJ7047 module

Several parameters have to be set before the motor can be started up. See chapter "Configuration of the TwinCAT NC".
Please set these parameters before continuing with the motor commissioning procedure.
