Hello friends,

I use one of V90 driver via profinet on my system. I have a big problem about reference on V90. I use absolute encoder and i create a zero point. Also i save it parameter p2525 on the driver but every power shutdown and open again it losts zero point. For example my actual position is "0" and power shuts down and after that i get power back. I read my actual position like "10000". That's a big problem for me. Can you help me?

Did you executed a copy RAM to ROM?
