Calibrating absolute encoder with Sina_Pos

Hi all,

I'm using an S120 with Starter V5.1.1.2, TIA V15.1 and Sina_Pos.

I want to reset the actual position of my axis to 0 using a button on the TP.

I can do this with Sina_Pos by setting 'ModePos' to 5 and executing.

This works fine, the actual position is set to '0', but when switching the power, it's back to the old value.

So it's not saved in the ROM.

Is this possible, how do I do this?

Thanks and best regards,
Jeroen

You can see the procedure for Absolute encoder adjustment at Chapter 11.2 of Manual: Function blocks to control the SINAMICS with SIMATIC S7 in TIA-Portal, at link: https://support.industry.siemens.com/cs/us/en/view/109475044
