Motor Feedback Wiring
Encoder feedback connections are made with the CFCS cable. This cable has an MS style
connector on the motor end and a 26-pin high density “D” connector on the drive end.
For A, A
, B, B and Z, Z pairs, the CFCS cable uses low capacitance (~10 pf/ft) wire to get a
characteristic impedance of 120 ohms. This impedance match is important to minimize signal
loss and ringing.
