My axis movements work normally, I can make the axis synchronous, there is no problem. But now I had to use an external encoder. Due to the gap in the reducer, I chose the SSI linear encoder for this, Turck brand, but I could not activate the second encoder. There are errors in the picture. Where am I doing wrong?

Bit 22: Positioning element is in the measuring range Only 5 Bits after position.

The length of the SSI ruler is 100mm, but I read 25mm in my movement measurement, what should I do as an adjustment from beginning to end?

Also make sure that you have copied RAMtoROM after encoder adjustment. Maybe the following application example can support you with the necessary settings. https://support.industry.siemens.com/cs/ww/en/view/102950703

I have shared all the information about the settings in the attachment. On the technology object and driver side When I enter the same value for Gx_XIST1 and Gx_XIST2, the measurement is incorrect but it saves the position when the power is cut off. But when I enter 11/9 on the driver side and enter 6/1 in the technology object, the measurement is correct, but it does not save when the power is cut off. What are the correct values based on this information? thank you Technology Team Hello edeskoray, please check the settings like resolution for you SSI encoder.

I set the Gx_XIST1 and Gx_XIST2 values of my position values to 0 on the driver and to side, but my 100mm ruler shows a value of 3.127 mm when I move from the beginning to the end. Which parameter is wrong? When I set Gx values other than 0, there is a problem saving the position value. edeskoray hello technology team I think my problem is related to the resolution settings.

Encoder evaluation seems correct. Drive is counting negative. 2517 -> 0 > 4294966781 (delta - 3031) because the overflow of te DWORD and TO is counting positive 0,2 > 3,232 (delta 3,032). Configure motorencoder as encoder 1 at the TO and external encoder as encoder 2 at the TO. Set encoder 2 as encoder for positioncontrol at the TO and use data adaption to avoid configuration errors. Then it is possible to switch between the encoders for positioncontrol and it's possible to use DSC,
