2.2.5. Primary Encoder Inputs

The primary encoder inputs are accessible through the Axis connector. Use the PrimaryFeedbackType
parameter to configure the SI4 to accept an encoder signal type.
Square Wave encoder signals:
Absolute encoder signals:
Refer to Section 2.2.5.3.
IMPORTANT: Physically isolate the encoder wiring from motor, AC power, and all other
power wiring
