Figure 2.45 shows the proper phasing of TTL A/B encoder signals
when positive current is applied.

Figure 2.46 shows the proper phasing of Sine/Cosine encoder signals
when positive current is applied.

Motor Encoder Connection Diagram
Figure 2.47 shows a typical wiring diagram of a motor feedback cable.
If the thermostat, limit, or Hall signals are not available, no
connections are required, but the drive must be configured through
software to ignore these signals. Refer to Appendix B for specific
Ultra3000 drive/motor interconnect diagrams.

Notice that the Sine/Cosine encoder signal phasing is
different than the phasing of the TTL encoders.

IMPORTANT
Total resistance of the wiring for +5V encoder power
and ground connections between the drive and
motor must be less than 1.4 ohms.
