What commutation offset do Kollmorgen motors have?

DBL / DBK with Encoder	Feedback has no defined commutation offset. The commutation offset is determined with the help of the servo amplifier and stored in the encoder memory.
AKM with Hiperface encoder	Encoder is installed arbitrarily. The commutation offset is determined with the aid of the servo amplifier and stored in the encoder memory.
AKM with BiSS encoder	Encoder is installed arbitrarily. Commutation offset is set to zero electronically.
AKM with EnDat encoder	Commutation offset is mechanically set to zero.
