What are people using for cable to connect from the VFD to the Spindle?

I know they recommend shielded/screened cable but I've also read in some places that it should be double shielded/screened. I've also read that you need to ensure that the cable has been designed to support continuous flexing.

Is 1.5mm2 CY cable ok to use? Can it stand the constant flexing that it will be subject to, and will its single shielding/screening be enough.

Cheers
