Hi everyone,
I use CODESYS Softmotion RTE V3 x64 and KEBA Drive with absolute encoder.

Firstly, I do homing and axis position is 0 degree.
When I power off and again power on the system, I read axis position 75824.75 degree.

How can I solve this problem ?
I attach my axis settings.
Thank you.

Hello, this is a "normal" behaviour with Softmotion and absolute Encoder in the drive.
You have to use SMC3_PersistPosition to store the "original" position also in the PLC.
Here you could find a description:
