Kollmorgen AKD series Installation Manual

9.12.5 SFD
The diagram below shows the connection of the four wire Kollmorgen SFD feedback system.
When SFD cable total resistance for 5V out (Up) and 5V return (0V) is less than 3.3 Ohm,
then remote sensing is not needed. For typical cable this means remote sensing is not
needed up to 25 m.
Kollmorgen cables are rated up to 50 m with no remote sensing.
