Baldor mn722 manual Encoder Installation, Encoder End Control End, Single Ended Connections

Encoder Installation	Electrical isolation of the encoder shaft and housing from the motor is required. Electrical
	isolation prevents capacitive coupling of motor noise that will corrupt the encoder signals.
	Baldor provides shielded wire for encoder connection. Figure 3-7 shows the electrical
	connections between the encoder and the encoder connector. Figure 3-8 shows the
	connections between the encoder connector and J1 of the control.

Single Ended Connections

Differential inputs are recommended for best noise immunity. If only single ended encoder signals are available, connect them to A, B, and INDEX (C) (J1-23, J1-25 and J1-27 respectively).

Buffered Encoder Output The control provides a buffered encoder output on pins J1-31 to J1-38. This output may be used by external hardware to monitor the encoder signals. It is recommended that this output only drive one output circuit load (a 26LS31 type device drives this output).
