Sensor™ THC 394
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 equal to the incoming voltage being
read can be entered here to “zero” the incoming voltage. Please refer to the installation instructions
later in this section for more details.
