For example : A PLC controller is programmed to provide 1024 line pulses
as an input command to a CDHD system in order to make the motor rotate
two revolutions. The settings are therefore:
External Encoder Resolution = 1024
Gear Ratio Multiplier = 2
Gear Ratio Divider = 1

If you experience noise, you may want to improve HDC tuning.
