first of all, there a no TNC probing cycles shipped with NX cam, neither for 640 nor for 530 controller.
The commands you see e.g. TCH_PROBE_500 are prepared in ccf file to call a subprogram. But as I said, the subprogram itself is not available OOTB. For legal reasons we are not allowed to ship them with the installation. So if you want to use them ask the customer or the manufacturer to get the cycle files in plain text and put them into the subprog folder of your machine.
If you want to call e.g. TCH PROBE 420. Simply add a subprog call within the mcf file with Machine Configurator.
