The Schleicher XSL module is connected to the Schleicher
PLC/CNC controller via intelligent Rack Mount. While
the Schleicher PLC/CNC controller transmits the movement
commands to the drives (motion of axes), the Schleicher
XSL module – in co-operation with the Schleicher PLC/CNC
controller – regulates the laser power through dedicated
functions. With the development of the Schleicher XSL module
co-joined with a Schleicher PLC/CNC controller, manufacturers of laser processing machines are now offered special
and unique capabilities allowing for a dynamic laser control
so as to obtain the highest quality in the finished product.

What are the characteristics of the Schleicher XSL module?
The Schleicher XSL module realizes switch on/off of the laser source with a precision of 1 microsecond, in correlation with the axis motion. The
module, with an internal cycle of 20 nanoseconds, was developed with the intention of countering the communication time delay typical of laser
system units. The high output resolution of 1 microsecond, aside of an extraordinary spatial and temporal precision, allows for release of accurately
complex pulse trains at high frequency. Laser pulses are positioned with high precision even at full axis movement without interrupting it.
What is the benefit - including unique features – of Schleicher XSL module?
The new level of precision becomes particularly apparent when micro-crosspieces are made during laser-cutting and laser-drilling processes.
While operators using conventional controllers have to accept considerable tolerances with respect to the positions and lengths of the crosspieces or the borehole distances, the high resolution offered by the Schleicher XSL module enables on and off switching with an accuracy unknown
until now. Other benefits include:

High granularity in cutting quality adjustment due to free definition of the laser pulses
Safety feature to prevent laser overload (Duty Cycle Limitation)
Highly enhanced quality of processed surfaces and cut edges
Suitable for many beam sources (Rofin, IPG, Trumpf, …)
In summary, the end user benefits of ultra-clean cut widths, unparalleled consistency in accuracy and speed resulting in highly decreased reject
rates and unusually short processing times.

Expansion Module XSL
What are the Fields of Application for the Schleicher XSL module?
Besides the classic fields of use such as laser welding, cutting or perforating, this technology now opens itself up to expanded applications
such as Laser Additive Manufacturing, material refinement and surface finishing within the glass and ceramics industries,
quality-optimized processing of composite materials or the creation and measurement of very fine structures.
What are the functions the Schleicher XSL module enables?
The Schleicher XSL module is equipped with fast outputs that are called “PSP” and “PWM” channel. Within the PSP output channel, 3 functions
enable the special features on the Schleicher XSL module and are provided and activated/deactivated through Schleicher’s fast M - functions:
+ A. PSP (Position Synchronized Pulse)
+ B. PWM (Pulse Width Modulation) - dependent of path speed
+ C. Drilling Mode – independent of path speed
Within the PWM output channel, 1 function is realized: static PWM.
A. PSP: Position Synchronized Pulse
About Schleicher
PSP generates a high precision pulse train within its parameters. The control of the laser
pulses is perfectly synchronized with the axis motion.Parameters are: “number of laser pulses”
per mm, and “active pulse width.” The PSP software pre-calculates the correct timestamp
and the position for the pulses output, in this manner obtaining equi-spaced pulses.

The special function PWM operates according to the resulting path speed. The function
allows for adjusting the duty cycle in order to obtain pulses featuring a duty cycle linear with
the path speed (fig 1). Additionally it is possible to adjust at 3 individually configured speed
