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)
1
View the S1 and S2 switch settings on the drive.
2
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.
