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 –
