Hello Gents,

I'm using absolute encoder for position control and everything seems OK. The problem occurs when I switch power Off/On I'm loosing "Reference point set" signal and It's seems I have to make axis reference once again. Before I was working only with SEW drive, and I have't problem like this. How can I solve this problem in Sinamics Drive??

If you use basic positioner (epos) you have to use p2507 for homing.

Then make a ram to ROM copy.

For that you can use the sina_para block for example in the plc if you want that or directly in the starter or startdrive software.
