2.9 Encoder Parameter
The control contains two encoder interfaces. The assignment of the pin connectors is identi-
cal.
Thefollowinglimitationsarevalidwhenoperatingwithtwoencoders:
• The voltage supplies 5V and 8V are generated with one programmable voltage source.
Onlyencoderswith5Vor8Vsupplyarepossible(e.g.BiSSandHIPERFACEarenot
possible).
• There is only one Endat core on the encoder interface, therefore operation of a digital
EnDat 2.2 encoder together with a EnDat analog encoder is not possible.
