8.10.10.1 X23 SFD Feedback
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 a typical cable this means remote sensing is not needed up
to 25m.
Kollmorgen cables are rated up to 50m with no remote sensing.
Type FBx.IDENTIFIED Up Description
Smart Feedback Device (SFD) 41 5.1 V ± 3.5%
Accuracy: 14 bit (0.022°),
resolution: 24 bit (2x10E-5°)
*SFD must always use AC coupled termination - DCtermination switch open.
