A.4 iHC User Interface
The iHC can be almost invisible to the operator while the Height Control Parameters can come from the cutting program or fully automatically
from the Material/Thickness/Tool parameter sets. Because this window does not hide any controls normally used to run the iCNC system it can
be viewed at all times. This chapter describes the User Interface at the controller when the automatic parameter setting features are not in use.
This allows for changes at the time of cutting and/or settings before starting to cut .
To start the software select “iHC.exe-Shortcut” from the Windows Start menu.
Main Bar
The large right pointing arrow can be used to make the iHC main bar smaller. This allow operator to see position and other information about
the machine.
• On the left side of the main window there is a display showing the set value for Arc Voltage. The Arc Voltage can be modified using the
left and right arrows on the sides of the slider. One click changes the voltage 1V or 0,1 volts.
• The “UP” and “DOWN” buttons can be used to move the torch in manual mode.
• “IHS Test button” causes the torch to drive down to find a plate. This feature can be used to test that the iHC plate sensing works properly.
The text on IHS Test button changes to “OK”. Clicking “OK” returns the torch immediately to the home position. If “OK” isn’t clicked the
torch returns to the home position after some time.
• IHS Set feature is used for two purposes. It can be used to set the Slowdown Height for the torch (where the torch starts to use lower
Find Plate Speed) or it can be used to show the plate height for iHC. When thicker material is placed on the table this feature is used
before the cutting process to make sure the torch will not collide to the plate on first piercing point.“IHS Set” uses the Find Plate Speed
to conduct the Plate Contact Test. After finding the plate, the torch returns to Slowdown Height. If necessary, the Slowdown Height can
now be changed by using the “Up” and “Down” buttons. Pressing ”OK” will cause the torch to return to the Home Position and save
the Slowdown Height parameter. When “IHS Set” is clicked, the text on the button changes to “OK”. After
