8.3: EtherCAT Network
An EtherCAT network enables high-speed control of multiple axes while maintaining tight
synchronization of clocks in the nodes. Data protocol is CANopen over EtherCAT (CoE)
based on DSP-402 for motion control devices.
Stations on EtherCAT are automatically addressed by their bus location. The first drive on
the network is station address -1. The second is -2, and so on.
EtherCAT Address (Station Alias)
View the S1 and S2 switch settings on the drive.
To optionally verify the S1 and S2 switch settings select AmplifierNetwork Configuration
from the CME 2 Main Screen to open the EtherCAT Settings screen as shown in the
following example.
As an alternate to the default addressing, switches S1 and S2 may be used to program a
station alias. The default address and station alias are always available. If the switch-
based station alias is used, it is the responsibility of the user to ensure that each drive has
a unique station alias.
