Setups 55
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 time to adjust
the pulse.
Pulse Off Time
When Automatic Pulse Mode is selected for pierce control the user can select Pulse on and off time
to adjust the pulse. The Off Time starts when the sensor signal falls below the next pulse threshold.
Creep Time
Specifies the period after pierce complete that the laser head travels at Creep Speed. Creep Speed is
determined by a setup parameter in the Speeds setup screen and is a percentage of the programmed
cut speed. After Creep Time is complete, the control accelerates to full cut speed.
Pierce Complete
The Automatic Pierce monitors voltage of sensors in the laser head to detect completion of the
pierce. This is used in conjunction with Pulse On Time, Pulse Off Time and next pulse.
Next Pulse
Based on sensors in the laser head, the system can determine when the next pulse occurs. The Next
Pulse will be delivered when the voltage drops below the Next Pulse setting.
Start Corner Power
The Start Corner Power allows the user to define a speed where the corner power analog signal will
be used to start to decrease laser power. This is defined as a percentage of cut speed.
See Corner Power graph, where the example shows this set to 80%.
Minimum Corner Power
This parameter defines the minimum laser resonator power to switch when the cut speed reduces to
zero in a corner. This is defined as a percentage of selected power (watts). See Corner Power graph,
where the example shows 30%.
