Drive Controlled Homing (SERCOS)

A SERCOS drive offers the homing function as a drive-controlled sequence. In this case, referencing is therefore not performed by the TwinCAT NC system, but by the drive itself. This sample shows how drive-controlled referencing is initialized and triggered by the TwinCAT PLC.

The procedure for saving and installing the sample program is similar to the Axis movement example. 

• Sample program Drive-controlled homing of a SERCOS axis: SERCOS HomingV1.0.5.zip

The sample program uses the following special error codes:

16#FFFFFF - The sample program does not support parameter scaling in S-0-0044.

16#FFFFFE - The SERCOS drive has aborted the referencing process with error.

16#FFFFFD - The referencing process has been completed but the drive has not set the reference flag in S-0-0403.
