A – ArcGlide THC Serial Communication Protocol
IHS Speed
Command ID Data Examples
IV 1 – 10 (approximately
5% – 25% of maximum speed) >IV5D4< Sets IHS speed to a relative value of 5 out of 10.
5 represents approximately 15% of the maximum speed or
about 90 in/min with the standard Hypertherm lifter.
>IV?DE< Query from the CNC.
IHS Speed sets the speed for the final approach to the workpiece during an IHS operation as a relative value between
1 (slow) and 10 (fast). These values represent 5 to 25% of the maximum speed of the lifter (15,240 mm/min or
600 in/min).
Default: 2
 IHS Speed command IV sets the speed on a scale of 1 – 10 to maintain compatibility with the Command THC. To
set IHS Speed in mm/min or in/min, use the IHS Speed command IS described later in this document.
Homing Speed
Command ID Data Examples
HS 1 – 10 (40% – 80% of
maximum speed) >HS2CD< Set home speed to a relative value of 2 out of
10. 2 represents approximately 45% of the maximum speed
of 6,858 mm/min or 270 in/min.
>HS?DA< Query from the CNC
Homing speed is the maximum speed for manual moves. It also sets the maximum speed used by the ArcGlide for
Arc Voltage Control. As the ArcGlide moves up and down when maintaining the set arc voltage, it does not exceed the
homing speed.
Default: 5 (5 is 60% of maximum speed)
 Homing Speed command HS sets the speed on a scale of 1 – 10 to maintain compatibility with the Command THC.
To set Homing Speed in mm/min or in/min, use the Slow Speed command SS described later in this document.
Nozzle Contact
Command ID Data Examples
NC 0 = OFF
1 = ON
>NC1C2< Enable ohmic contact.
>NC0C1< Disable ohmic contact.
>NC?D0< Query from the CNC.
When Nozzle Contact is on, the ArcGlide uses ohmic contact to sense the plate. Disable Nozzle Contact to use stall
force sensing (for example, with a water table or painted workpieces where electrical contact is unreliable).
Default: Previous setting
