Buffered Motor Encoder Outputs
The Ultra1500 includes buffered motor encoder outputs. These signals are
generated by the drive after filtering and processing the actual feedback from
the motor.
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. Figure 2.22 shows the configuration
of the Ultra1500 encoder outputs.

Total resistance of the wiring for +5V encoder power and
ground connections between the drive and motor must be
less than 2 Ohms.
