Creating a DC link

The DC link concept has the advantage that in multi-axis systems the drives can be coupled in the DC link, so that they can exchange energy.
Using this approach you can determine:

  • the required feed-in power and
  • any braking power that may be present in the DC link network.

@@Subsequently, the synonym "DC link" will be used.

Specifying the project properties

Before you can add a DC link, you have to specify your project properties. The project properties are specific data referring to the project you created. This data is applied to your report. Creating a report.

 

Procedure

  • Right-click on your project.
    A further menu window opens.
  • Left-click on "Project Properties".
  • Complete the information fields

Note:

You do not have to save the inputs separately. Any information you add is automatically saved when you exit the input window.

Adding a DC link

Entering the DC link settings

  • In the Solution Explorer right-click
    on the newly created TC3 Motion Designer project.
    A new menu window opens.
  • Click on "Add DC Link" (1)

Creating a DC link 3:

Supply (1):
Here you can choose between 1- or 3-phase alternating voltage or a direct voltage (DC) power supply (only for servo terminal EL72x1) for your supply network.

Supply voltage:
In the selection menu (2) you can set the unit for the supply voltage. Possible units are V, mV or kV.

Product group (3):
Here you can choose between the servo drives of the AX5000 and AX8000 series and the EL72x1 servo terminal (only possible if a direct voltage (DC) power supply was selected).

Confirm your DC link settings with OK (4).

Creating another DC link

To add a further DC link, repeat the above steps. The voltage set for each created DC link is constant and can no longer be changed subsequently.

Notes regarding the supply voltage!

Information regarding permitted supply voltages can be found in the technical data for the AX5000 and AX8000 servo drives and the EL72x1 servo terminal. For technical data please refer to the system manuals and other documentation. These can be found on the Beckhoff website at: www.beckhoff.com.
