6 Operating Behavior on EtherCAT
®
This chapter describes the basic behavior of the inverter in connection with EtherCAT
®
with control via process data objects (PDO) for fieldbus communication.
6.1 Controlling the MOVIDRIVE
®
MDX61B drive inverter
The MOVIDRIVE
®
B drive inverter is controlled using the fixed PDO, which are 10 I/O
words long. When using an EtherCAT
®
master, the process data words are directly
mapped in the process image and can so be addressed directly by the control program.
6.1.1 Control example in TwinCAT with MOVIDRIVE
®
MDX61B
Once the file SEW_DFE24B.xml has been copied to the TwinCAT subdirectory "\IO\Eth-
erCAT", you can use the function "Append box" in the "offline" mode to insert a
MOVIDRIVE
®
B in the EtherCAT
®
structure (see following figure).
