2 – Installation
IHS Complete: This is an optional signal output from the ArcGlide to the CNC that is used only when the CNC has to
synchronize IHS for multiple ArcGlide systems. This signal is used to indicate that the initial height sensing
(IHS) is complete and that the torch is in position and ready to fire. For multiple torch installations, the CNC
should wait for all active torches to return an IHS Complete signal before simultaneously removing the Hold
Ignition signal and allowing all torches to ignite at the same time. For single torch installations this signal is
not used.
Retract Complete: This signal is an output from the ArcGlide that is active when a cut is completed and the torch has
been raised to the selected Retract Height. The CNC uses this signal to delay the move to the next cut and
to clear any tip-ups.
Cut Sense: This is a required output from the ArcGlide to the CNC. This signal is issued after plasma torch ignition and
the Pierce Delay (Pierce Time in Phoenix software) time has expired. This signal indicates that the CNC
should begin the cutting motion.
See
Operation on page 127 for more information on Pierce Delay.
THC Error: This is an output from the ArcGlide to the CNC that indicates that the THC has encountered an error
condition. The HMI displays the actual error condition.
See
ArcGlide errors on page 191 for more information about ArcGlide error messages.
Breakaway Error: This output from the ArcGlide indicates that the torch breakaway has separated. This output is reset
by replacing the torch breakaway.
Interlock input: This is a normally-closed contact closure that allows ArcGlide motion. If this contact is opened, the
ArcGlide lifter motor drive will lose power. This circuit must be wired according to national and local
regulations.
Interlock output: The Interlock output is an independent contact closure that is also normally-closed. The Interlock
output must have the same state as the Interlock input.
