	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

According to the FAQ bellow, it can be connected directly to SINAMICS, SIMODRIVE or MASTERDRIVES. Measuring systems with EnDat 2.2 and EnDat 2.1 - compatibility Hope this helps.
