152 Operator’s Manual
Cut Height
The Cut Height setup parameter is used to select the desired cut distance above the plate. This
will set the initial cut height before the laser cut motion is activated. Cut Height is derived from the
CHS signal and the calibration curve and represents cut distance from nozzle tip to the plate.
Pierce Height
The Pierce Height setup parameter is used to select the desired Pierce Height above the plate.
This can be entered as a multiplication factor that is calculated times the Cut Height or an actual
Pierce Height distance.
Lens Cut Position
Sets the focal lens position in the laser head for cutting.
Lens Pierce Position
Sets the focal lens pierce position in the laser head for cutting.
Pulse Laser Time
Sets the Laser Pulse Time duration for a one shot beam alignment.
Pulse Laser Power
Sets the Laser Pulse Power for a one shot beam alignment.
Height Control Manual/Automatic
Allows the user to either select a Manual or Automatic Height control for the laser head.
IHS in Manual
The IHS in Manual setup parameter allows the operator to select whether or not to use the Initial
Height Sense feature when operating the Sensor THC (THC1) in manual mode.
Retract Full/Partial
Selects the retract distance to be set at Full or Partial. In the Full retract mode, the laser head will
retract to the Z-Axis Home position. In Partial retract mode, the laser head will retract to the set
retract distance.
Partial Retract Distance
This setup parameter is used to select the THC Retract Distance when configured for partial
retract mode.
Start IHS Distance
The Start IHS Distance specifies the distance of travel for the THC to move the laser head at high
speed before switching to low speed and beginning Initial Height Sense. Caution should be taken
when selecting this distance so that the laser head does not crash into the plate.
Preflow During IHS
Selecting ON will activate Preflow gases during the IHS cycle.
Nozzle Contact IHS
This parameter would be set to ON to select the THC to use Contact Sense to detect the plate
during the IHS cycle.
Nozzle Contact During Cut
Nozzle Contact During Cut allows the CNC to detect contact with the plate and generates a fault
if this condition occurs.
