Sensor THC

THC Slow IHS Speed
The THC IHS Speed is used to retract the torch after the plate has been sensed. The torch
will retract at this speed until the contact sense is lost. This determines the exact distance
to the plate, regardless of any flexing of the plate. A very small speed is recommended
for optimal accuracy.
Note: Due to the quick response time of the Sensor THC, generally there is no need for a
value to be entered at the “Distance to Corner” parameter to lock or “freeze” the position
of the torch. It is, however, suggested that a value be entered for the “Distance from
Corner” to stabilize the torch during acceleration.
THC I/O
Analog Offset 1 - 12
The Analog Offsets 1 through 12 are used to correct for any imbalance or “zero” the
incoming analog voltage to the Analog Input Card. Analog inputs are assigned to the
THC Axis and the Analog Offsets for the appropriate THC Analog input may be adjusted
here.
To calibrate the Analog Inputs, jumper the two pins specific to the input together and
view the incoming voltage at the Diagnostics Analog I/O screen. The incoming voltage
should be zero. If any voltage is displayed at the diagnostic screen, an Offset Voltage
