3.2. Auxiliary Encoder Input [-EB1]
The Auxiliary Encoder connector gives you a second encoder input channel. This channel is typically used
for dual loop applications.
Use the AuxiliaryFeedbackType [A3200: PositionFeedbackType or VelocityFeedbackType] parameter to
configure the XC2 to accept an encoder signal type.
Square Wave encoder signals: Section 3.2.1.
You can configure the Auxiliary Encoder interface as an output that will transmit encoder signals for
external use. Use the DriveEncoderOutputConfigureInput() function [A3200: EncoderDivider parameter]
to configure the Sine ± and Cosine ± connector pins as RS-422 outputs. You can only echo incremental
square wave primary encoder inputs.
