Purge Time
Specifies the time delay for cutting gas purge before start of the laser cut motion is enabled.
New Gas Purge Time
Specifies the Gas Purge Time for switching from one cutting gas to another cutting gas.
Shutter Time
The Shutter Time parameter is used to specify the amount of time to open the shutter prior to the
laser beam on.
Power Ramp Time
The Power Ramp Time parameter is used to specify the amount of time to ramp up the laser
power prior to the laser pierce.
Pierce Time
Specifies the time delay from when laser head completes lowering until motion is initiated at
creep speed for cutting.
When Manual Pierce Control is selected – This is the total pierce time allowed.
With Automatic Pierce Control is selected – This time is an additional delay after pierce is
complete.
Pulse On Time
When Automatic Pulse Mode is selected for pierce control the user can select Pulse On and Off
Time to adjust duty cycle response of the sensor pulses from the laser cutting head.
Pulse Off Time
When Automatic Pulse Mode is selected for pierce control the user can select Pulse On and Off
Time to adjust duty cycle response of the sensor pulses from the laser cutting head.
Creep Time
Specifies the amount of time after piercing the material that the laser head travels at Creep
Speed for cutting. Creep Speed is determined by a setup parameter in the Speed Setup Screen
and is a percentage of the programmed cut speed. After the Creep Time is completed, the
control accelerates to full cut speed.
Beam Off Time
The Beam Off Time parameter specifies the amount of time the beam output will be turned off
prior to he stop of motion. This feature can be used to tab parts for attachment to the skeleton.
Postflow Time
Specifies the amount of time that the cutting gas remains on after the cut is complete.
