Appendix C Sin/Cos Linear Encoder and Kinetix 6000 Drives
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 When installing a Sin/Cos linear encoder, setup the Axis Property tabs by doing
the following.
1. Click the Motor Feedback tab.
2. Enter the following parameters.
Parameter Value Comment
Feedback Type Sin/Cos –
Cycles 25 per Millimeter For 40 µ pitch encoder scale.
50 per Millimeter For 20 µ pitch encoder scale.
Interpolation Factor 1024 –
