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 parameter to configure the drive to accept an encoder signal type.

Square Wave encoder signals: Square Wave Encoder (Auxiliary)

Absolute encoder signals: Absolute Encoder (Auxiliary)

Sine Wave encoder signals (with the -MX3 option): Sine Wave Encoder (Auxiliary) [-MX3 Option]

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 ±, Cosine ±, and Marker± connector pins as RS-422 outputs. You can only echo incremental square wave primary encoder inputs or, with the with the -MX2 or -MX3 option, incremental sine wave primary encoder inputs.
