Motor Encoder Connection Diagram
Figure 2.23 shows a typical wiring diagram of a motor feedback cable.
If the thermostat or limit 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 Ultra5000 drive/motor
interconnect diagrams.

Drive/Motor Wiring Diagram
Unbuffered Motor Encoder Outputs
The Ultra5000 passes the motor encoder signals directly to the CN1B
Auxiliary Encoder Output connector without any conditioning.
Buffered Motor Encoder Outputs
The Ultra5000 includes buffered motor encoder outputs. These signals
are generated by the drive after filtering and processing the actual
feedback from the motor. Programmable division is also available.
The buffered motor encoder outputs use RS-485 differential drivers
and have a maximum signal frequency of 2.5 MHz. The drivers can
drive a 2V differential voltage into a 100 ohm load.
IMPORTANT
Total resistance of the wiring for encoder power and
ground connections between the drive and motor
must be less than 1.4 ohms.
