Encoder following command source is implemented by connecting the input encoder (auxiliary encoder of the 
master motor) to high-speed digital inputs (HS_GPI). Encoder channel A must be connected to high speed digital 
input 1, and channel B to high speed digital input 2. Connection examples for the differential and single ended 
master encoders are shown in the next figures:

7.7 Communications

The Nix Servo Drive provides the following network communication interfaces for configuration and operation:

•

USB
