Example: TwinCAT

Motion Control via EtherCAT

7.2.2

Settings for Position mode 

• The position setpoint is transferred via the input word configured in the PDO Editor.
• The position is transferred via the output word configured in the PDO Editor. The

resolution is set during startup.

7.3

Example: TwinCAT

Configuring clock 
synchronous 
operation

Make the settings shown in the following figures.

For clock synchronous operation, select the "DC for synchronization" option on the DC
(Distributed Clock) tab page. Make sure that the cycle time in the "Cycle time" field
matches exactly the synchronization time set in parameter 9963.1.
Please check the settings of the watchdog.
Possible times for "Distributed Clock": 500 µs, 1 ... 10ms.
