CNC functions
CNC I/O circuits provide at least 1000V galvanic isolation from the plasma power supply.
While the CNC circuits are isolated from the power supply, many of the signal returns on J15 and TB1, TB2 & TB3
are common to each other. J15 pins 1, 4, 5, 10, 17, and TB1-1, 5, 7, 9, and TB2-1 & 3 are all common. J15 pin 12
and TB2-10 are also connected to the others when SW6 (OK to Move select) is set for voltage.

1 SW6 on CCM I/O PCB selects OK to Move for isolated contact closure or DC Volts (15-18V) at <100ma. When
set for contacts, OK to Move circuit is rated for 120 VAC / 28 VDC
