2.5.1. Auxiliary Encoder Interface

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:
Absolute encoder signals:
Sine Wave encoder signals (with the -MX3 option):
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 or, with the -MX2 or -MX3 option,
incremental sine wave primary encoder inputs. You cannot use the absolute encoder interface when
you echo incremental signals.
