2.5.1. Auxiliary Encoder Inputs
The Auxiliary Encoder connector gives you a second encoder input channel. This channel is typically used
for dual loop applications.
Use the AuxiliaryFeedbackType parameter to configure the XL5e to accept an encoder signal type.
Square Wave encoder signals: Section 2.5.1.1.
Absolute encoder signals: Section 2.5.1.2.
Sine Wave encoder signals (with the -MX3 option): Section 2.5.1.3.
You can configure the Auxiliary Encoder interface as an output that will transmit encoder signals for
external use. Use the DriveEncoderOutputConfigureInput() function 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.
