Hi,

Unlike Beckhoff terminals, servo drives are very complex ethercat slaves.
Often you have to send SDO commands to the servo drive to configure PDO mapping. After that you can communicate with the servo drive with PDO.

this is an example for Kollmorgen AKD:

For Beckhoff terminal you do not have to

Hello all,

we would like to use EtherCat Master to communicate to a SoE drive, but we do
not know how to proceed. We have been able to use EtherCat Master to communicate
to Beckhoff terminal modules properly, but it doesn't seem that we have to use
the same commands to send/receive information from the SoE drive.

Could anyone send a small explanation about the steps/commands we should use?

Thank you very much.
