What is the correct way to ground the shielded cables?
There is no absolute 'correct way' but a method that works is...
Create a single point (star) earth tag at your controller end. This star should be connected to your incoming Earth. The shields of all screened cables should be connected to this star and those shields left unconnected at their other end. Any other components Earths should also be connected to this star point.
Do not create any Earth loops or GND loops - single point connection is the way to go.
