What does the encoder index pulse (Z) do?
The Z (index) signal is triggered once every revolution of the encoder. This signal is typically used for aligning data in a rotational application. When the Z signal is connected, Gocator would capture the encoder tick at which the Z index occured and send it out over Ethernet.
The encoder value at the last encoder index (last Z pulse) can also be retrieved in the SDK via the function call:
GO2_EXPORT(Go2Int64) Go2Data_EncoderIndexValue(Go2Data data);
