I think what they are meaning is normally you will have 2 encoders unless the motor is direct drive as in my case. So that way I can use the encoder for both.
As said however my actual encoder is not suitable as it is sine/cosine but as my servo drive can be set to send out interpolated encoder signals rather than just passing them out it works fine.
Although the Orient isn't working. Whether that is the drives output or the IP-A that is at fault I am not sure. I suspect it may be the drive as I looked at the drive in its software and I never saw the Index pulse change, it was constantly on. That stands to reason as there is no index pulse on the encoder with it being a Sine/Cosine encoder, I however thought the drive would manufacture one, maybe it is not correct, I will have to haul out the scope one day and see.
Main thing is you have it working by other means.
