CNC Machine Interface Connections
Perform the following steps to properly interface the SR-45i system with a CNC
cutting machine. See the system schematic for additional information.
Plasma Start Signal
•
The SR-45i requires a contact closure between P8 pins 3 and 4 to commence
the cutting sequence. The cutting sequence is terminated when the contacts
are opened. The contacts should be rated for 24VAC - 10mA.
Motion Output Signal
•
The SR-45i provides a maintained contact closure or 24VAC output between
P8 pins 12 and 14 as long as a cutting arc is maintained between the torch and
the workpiece. To configure the motion signal for a contact closure, connect a
jumper wire between terminal block TB1 positions 11 and 13. To configure
the motion signal for 24VAC, connect a jumper wire between terminal block
TB1 positions 10 and 11 and another jumper wire between terminal block
TB1 positions 12 and 13. TB1 is located on the sub-panel of the system
behind the rear panel. The motion contacts are rated for 10A - 250VAC or
10A – 30VDC.
