3.2. Auxiliary Encoder Interface [-EB1/-EB2]
The Auxiliary Encoder connector gives you a second encoder channel. This channel is typically used
for dual loop applications.
Use the AuxiliaryFeedbackType [A3200: PositionFeedbackType or VelocityFeedbackType] parameter
to configure the drive 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.
