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 & 2 are com-
mon to each other. J15 pins 1, 4, 5 & 10 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.

on TB1, TB2 & TB3.
2 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 @ 1A.
Internal CNC connections. TB1, TB2 & TB3 on CCM module.
Connections are provided on the CCM module TB1, TB2 & TB3 terminal blocks including most of the rear panel
functions plus some additional features. All these signals are isolated from the plasma power supply but signals
marked (comm.) and (-) are common to each other.
Users are expected to install their own CNC cable to these connections. Knockout hole is provided in rear panel of
CCM module. User shall provide strain relief / cord grip for user installed cable.
