redPOWER QUBE Cased Fiber Laser User Manual
9.3.5 Ramp Up
When output is demanded it will linearly increase from zero to the demanded level over this
period.
9.3.6 Ramp Down
When the output is turned off, its power will decrease to zero over this period.
9.3.7 Trigger Mode
Selecting one of the External Modes allows the QUBE Fiber Laser to be controlled by a
Trigger signal applied to the Trigger Input (Pin 16) on the Machine Interface (PL5, section
7.6.5).
Internal: Output pulses generated at rate set in the parameter editor, using internal
function generator.
External Edge Triggered: One output pulse is generated for each positive going edge
on the Trigger inputs. Not for CW mode.
External Gated: Output is enabled while the Trigger input is held high, and turned off
for Trigger input low.
9.3.8 EPC (External Power Control)
Allows the demand level to be controlled by the value of the voltage applied to the Analogue
Input (Pins 11 and 24) on the Machine Interface (PL5, Section 7.6.5).
The EPC indicator in the Status Indicators area will turn red if EPC is in use for the Active
pulse shape.
Off: Analogue Input level ignored.
Absolute: An input of 0-10V will control the peak demand for the pulse shape from 0-
100%.
Relative: An input of 0-10V will control the peak demand for the pulse shape from 0%
to the maximum value set in the pulse shape parameters.
Note: By setting the pulse shape to CW and using EPC mode, the output of the QUBE Fiber
Laser can be made to follow any arbitrary externally applied waveform.
9.3.9 User Defined Pulse Shapes
Any arbitrary pulse shape can be defined using the Shape Editor. The Shape Editor works
with dimensionless shapes that are then saved as a particular User Defined pulse shape. This
pulse shape can be used in any parameter set, where it is scaled to the peak power and pulse
width associated with that pulse shape.
