I have an application that use a 25hp AC drive from Lenze. This drive is at least 10 years old.

Does anyone know of a CanOpen/SERCOS interface or CoDeSys controller that will send out a +/-10 speed reference and encoder feedback.

The encoder is a Kuebler.

Hi,
one option is for sure to do this by using CODESYS V3 and Ethercat:

There is an example project here:
"c:\Program Files (x86)\3S CODESYS\CODESYS\Projects\SoftMotion\4.1.1.0\Examples\Tutorial\PosControl.project"
BOM:
-SoftMotion capable CODESYS V3 plc
-Ethercat EK1100
-EL4031 -> AnalogOut-10…+10 V, 12 Bit
-EL5101 -> Incremental-Encodern
