Pinouts for the discrete cable for the expansion PCB

Use this table to identify the signals, pin numbers, and wire colors in the interface cable with discrete connectors for the expansion Printed Circuit Board (PCB).

Table 1. Pinouts for the discrete cable for the expansion PCB
End A
Pin number Input/output Signal Function Wire color
1 Input ALT 24 VDC + (+24 VDC)1 Externally supplied 24 VDC lets communications for the control PCB and fieldbus continue when three-phase power is OFF. Red
2 Input ALT 24 VDC - (GND)1 Black
3 Input R_RMT_ON-OFF + (24 VDC)2 Both signals are necessary for the plasma power supply to work with the redundant remote on-off feature. White
4 Input R_RMT_ON-OFF - (RTN)2 Black
5 Output Output estimated arc voltage OUT + (0 V – 10 V)3 Estimated arc voltage output (0 VDC - 10 VDC) is available for torch-height controllers to work. Green
6 Output Output estimated arc voltage OUT - (GND)3 Black
Shield Overall shielding of the wires. The shield wire is connected to the CNC chassis ground. Bare wire
1 A 24 VDC (500 mA) and return (GND) from the Computer Numerical Control (CNC) or controlling device to the expansion PCB are necessary for the alternate 24 VDC to work.
2 A 24 VDC (50 mA) and return (GND) from the CNC or controlling device to the expansion PCB are necessary for the redundant remote on-off to the main control PCB to work. Hypertherm® recommends the use of a separate cable between the remote on-off input and main control PCB.
3 Estimated arc voltage analog output (0 V – 10 V ). The default ratio is 30:1. For information about how to use the XPR® web interface to change the voltage ratio and offset, refer to Use the XPR web interface to change the arc-voltage output scale. For information about how to use serial RS-422 or EtherCAT to change the voltage ratio and offset, refer to the CNC Communication Protocol for the XPR Cutting System (10085793).
