PRODUCT UPDATE CONTROL AND GUIDANCE Ensemble QLe piezo drive G6 series laser process heads
Laser Components’ partner Haas Technologies now offers various laser
process heads for fibre lasers. The G6 series laser process heads were developed for fibre lasers with a high output power between 4kW and 5kW and are typically used for high-speed cutting applications. User-friendliness plays a central role in the G6 series, and compartments make it easy to change the optics and adjust the focal distance. They also facilitate the exchange of the protective windows – standard 1.1-inch optics are used for this purpose.
The G6 system is particularly adaptable and the application of several focal length combinations is possible, as is the use of patented TLC optics (with a reduced thermal
Aerotech’s new Ensemble QLe panel-mount nanopositioning piezo drive is designed for use with the Ensemble family of drives and controllers. The QLe connects to any Ensemble controller network, enabling coordinated motion between piezo stages and servo axes at much higher rates than other controller or drive products. It is ideal for applications ranging from demanding scientific research to advanced OEM machine systems. Featuring a dual-
lens). A QBH and other fibre connections are suitable, as well as an XY adjustment of the lenses.
The PHF-25 series is made for a medium power output of up to 2kW. For a low power output of approximately 100W, the new PHFM series is available. This series features a compact design, and easy handling through an SMA fibre connection. One application in this power range is the laser welding of plastic.

core 456MHz, double- precision, floating-point DSP, the QLe drives provide extreme processing power over a wide variety of applications, including point-to-point motion, linear and circular interpolation, multi-axis error correction, and autofocusing. High-speed interrupts and data logging capabilities ensure a real-time link to external systems. The QLe also offers high-speed position latching capability and multi- axis position synchronised output (PSO) for generation of pulses based on actual position feedback, in applications ranging from laser firing to data acquisition system triggering. Using the latest technology and high-resolution A/D and D/A converters, the QLe enables sub-nanometre positioning resolution at high bandwidths. Capacitive sensor feedback circuitry
LaserDesk 1.2 software
Scanlab has introduced the latest version of its LaserDesk program used to create laser marking and material processing jobs. Available immediately, version 1.2 offers new features, including a ‘parameter assistant’ to optimise all laser and scanner parameters for any processing task. Deeper integration with Scanlab’s Scanalign calibration solution ensures marks are positioned on the workpiece exactly. LaserDesk1.2 can be used in normal mode, or remotely – for automated execution of laser jobs – or offline as a pure office version. Efficient operation of laser systems can be simplified via intuitive software that lets users create marking templates and set up
provides ultra-low noise performance over the full travel range with good thermal stability and long- term holding stability. Linearity is better than 0.01 per cent over the full travel range in closed-loop mode.
In addition to the four optically-isolated digital inputs, two high-speed digital inputs, and four optically-isolated digital outputs, the Ensemble QLe is equipped with analogue inputs and outputs. For precise applications, the QLe offers an 18-bit analogue input that can be configured to accept an external feedback sensor or position command. This analogue input also allows the high-voltage power amplifier to be controlled directly by an external low-level analogue input. Also, the QLe has one 20-bit analogue output that can be configured for position or voltage monitoring at high resolutions. Ensemble software uses advanced PID servo loops with feedforward and multiple integrators, coupled with eight programmable filters to supply the user with all necessary tools needed to optimise motion performance. Additional software options, such as Aerotech’s Dynamic Controls Toolbox and Motion Designer packages make available a host of tools that can improve tracking errors and
provide faster step-and-settle times. These tools include Learning Control, Harmonic Cancellation, Command Shaping, and Cross-Axis Feedforward.

is achieved because, even during execution of complex jobs, users can select diverse processing sequences immediately. New remote commands now enable the

program’s integration into system control as ‘slave’ or as ‘master’, thereby allowing fully automated complex marking operations and dependencies. The new ‘parameter assistant’ greatly simplifies determining and setting key process parameters – for example, laser powers, laser frequencies and scanner delays – for a specific job. Optimal parameter settings can be issued, read or selected via a tiled overview with a pre-defined test structure or customisable elements.
