Encoder Counting Direction
Normally, the encoder signals will output sine-leads-cosine (AM leads BM) when
the linear encoder head is moving towards its cable, relative to the encoder scale.
SERCOS drives count this in a negative direction.
Set Up the Axis Properties
Do these steps to install a Sin/Cos linear encoder.
1. From the Motor Feedback tab, enter these parameters values.
