Function
RS-422 serial inverting receiver.
RS-422 serial non-inverting receiver.
RS-422 serial inverting transmitter.
RS-422 serial non-inverting transmitter.
Machine cable recognition used for verifying installation of
Machine interface cable to CNC.
IHS Sync holds torch firing, but allows preflow gas to flow.
Auto Height On/Off enables or disables Auto Height.
Auto Height is Off when input is active.
Cycle Start (plasma start) initiates start of programmed cycle.
CNC must provide a contact closure to activate this input.
IHS Complete output to CNC to synchronize multiple torch
installations. When all connected torches are in position,
IHS Sync In signal is deactivated to proceed with torch ignition.
Retract Complete output verifies to CNC that the torch has
retracted and it is safe to move to next start position.
Pilot Arc output verifies to CNC that a pilot arc has been
established.
THC Error output alerts CNC that an error has occurred.
Machine Motion output verifies to CNC that a pierce delay
has been completed and notifies CNC to start movement of
the cutting machine.
