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.

Note: For non-Emerson motors the thermal switch minimum requirements
are as follows:
Operation = Open on rise
V(min) = 10VDC
I(min) = 1 mA
If a thermistor is used, the motor fault will occur when the thermistor
resistance is approximately 1.0 k ohm.
