7.3.12 Setting a DC synchronisation

• DC synchronisation is absolutely required for Motion applications.

• DC synchronisation can also be used for Logic applications.

• Not all slaves support the DC functionality.

• In order to be able to use the DC functionality, the first slave connected to the EtherCAT master

(Lenze Controller) must have DC master capability.

When additional slaves are added, devices with and without DC capability can be mixed.

• The first EtherCAT slave after the Lenze Controller must

be the DC master that supplies the

other EtherCAT nodes (incl. controller) with the exact time.

 Note!

The manual configuration of the slave DC features requires detailed knowledge

regarding EtherCAT and the field device. Thus, DC settings should only be made by

experts.

We recommend that the basic DC settings be retained in the case of Lenze field devices

in order to ensure correct DC synchronisation.
