Minimum Corner Speed
Defines the minimum speed to use when negotiating corners. The CNC has centripetal
velocity and acceleration contouring algorithms which provide optimal cut quality for
most cut operations. In some situations, a minimum corner speed prevents over-burning
at corners. In normal operations, this parameter should be set to zero.
Fast Home Speed
Defines the speed that the CNC uses during the first phase of the homing sequence.
During the first phase, the cutting device moves toward the home limit switches at the
fast rate.
Slow Home Speed
Defines the speed that the CNC uses during the second phase of the homing sequence.
During the second phase, the cutting device moves off the home limit switch and
proceeds to the marker pulse. When the CNC detects the marker pulse, it decelerates to a
stop and performs a small move in the opposite direction to the marker pulse.
Creep Speed Percentage
Defines what percentage of the machine cut speed will be used when creeping.
Generally, creep speed is 25% of the cut speed.
Plasma Hi/Lo Speed Percentage
Specifies the percentage of the Cut Speed at which the CNC activates the Torch Height
Disable output. The plasma system uses this output to switch from low to high current or
to disable the height control.
Note: The Dual Grid/THC feature must be enabled at the Plasma Setups Screen.
Plasma Distance To Corner
Specifies the distance before turning a corner at which the plasma system should switch
from high current to low current and disable the automated height sensor. Distance to
Corner is active whenever the speed drops below the Plasma Hi/Lo Percentage, or
segments intersect at an angle greater than the tangent angle.
Note: The Dual Grid/THC feature must be enabled at the Plasma Setups Screen.
Plasma Distance From Corner
Specifies the distance after turning a corner at which the plasma system should enable the
Automated Height Sensor. Distance from Corner is active whenever the speed drops
below the Plasma Hi/Lo Percentage, or segments intersect at an angle greater than the
tangent angle.
Note: The Dual Grid/THC feature must first be enabled at the Plasma Setups Screen.
