2.8. Aux Encoder Connectors
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 drive rack to accept an encoder signal type.
Square Wave encoder signals:
Absolute encoder signals:
Sine Wave encoder signals (with the -CT4 option):
High resolution or high-speed encoders can require increased bandwidth for correct operation. Use
the High Speed Mode of the AuxiliaryEncoderMultiplierSetup parameter to enable the high
bandwidth mode. Because this mode increases sensitivity to system noise, use it only if necessary.
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 -CT2 or -CT4 option, incremental
sine wave inputs. You cannot use the absolute encoder interface when you echo incremental signals.
