Sin/Cos Linear Encoder and Kinetix 6000
Drives
Introduction This appendix guides you through commissioning a linear motor with a Sin/Cos
1V peak-to-peak output linear encoder.
Kinetix 6000 Drive
Feedback Connection
For robust operation when interfacing your Sin/Cos 1V peak-to-peak differential
output linear encoder to a Kinetix 6000 drive, terminate the sine and cosine
signals as follows.
For systems where the cable length is less than 10 m (32.8 ft), the encoder power
supply from the Kinetix 6000 drive feedback connector should be dropped from
its nominal 5.4…5.1V DC with the addition of a Shottky Diode; see the
schematic.
