This LENZE EVS9328-ES inverter is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
Servo inverters of the 9300 series with a matching motor and geared motor programme form a perfect drive system. Market-oriented intelligence enables general technology functions (electrical shaft or positioning control) as well as electronic alternatives to mechanical components (register control, cam profiler).
Thus, costly upgrades with control cams, pull rods, and also clutches are not necessary in the manufacturing process.
These intelligent drives coordinate - accurately and precisely - all different movements of the machines to one another. No matter whether the system is equipped with a central control station or is controlled locally - high flexibility is guaranteed.
This drive concept offers automation solutions based on a consistent platform.
Attachable InterBus and PROFIBUS fieldbus modules are available for the connection to a host control system.
The hardware of the servo product series is uniformly equipped with the following features:
Universality - the product series is universally applicable in the power range from 0.37 to 75 kW.
Integrated mains input - for single drive operations only one element instead of two separated elements is required. Regenerative power supply modules - ensure energy-saving group applications and multi-axis applications.
Feedback systems - ensure a perfect adaptation to the machine requirements by means of resolvers or SinCos feedback.
This inverter implements frequently used functions of a servo drive. The electronic gearbox is an essential technology function in this device. As an alternative to the mechanical vertical shaft, several drives can be operated at exact synchronisation by master frequency preselection. Proportional synchronisation can be implemented easily and flexibly by means of adjustable gearing. Feedback systems such as resolvers or SinCos encoders provide highest precision.
9300 register control
There are many machines that are processing material lengths. Second printings, cuts, perforations, embossings, or splices require the material length to be positioned precisely to form the resulting print image. However, due to process-dependant fluctuations (material characteristics, production parameters) the position of the print image tends to drift. The basic prerequisite "autosyn" is added by the requirement for overlaid register alignment of the rotative motion at the print image. The register control already integrated in the servo inverter always re-aligns the angular position of draw-in rollers, printing cylinders, or other processing stations with the print image. Thus, second printings, cuts, perforations, embossings, or splices will always be at the required position. Finally, drift errors are a thing of the past. Even without host control and without overlay gearing.
9300 cam profiler
Mechanical cams can be found quite frequently in production machinery. Changing or modifying the product causes lengthy and complicated set-up procedures.
The 9300 servo cam profiler can store up to 8 different cam profiles, so that cam profiles can be switched without delay during production. For a multitude of potential applications of the cam profiler a variety of additional functions have been integrated, e. g. electronic cam switches and marker-controlled cam start. Especially for opening and closing of welding bars a function has been integrated in order to achieve constant welding periods
at variable clock frequencies.
9300 positioning control
Positioning made deceptively simple. The 9300 positioning control includes a complete position controller with sequence control. Easy commissioning with only few input values is a modern solution as compared with external position controllers and their complicated programming language. Responses from limit switches or other drives can be evaluated at the same time. If the initial position of the product is tainted with considerable tolerances, the target position is reliably found by automatic material correction.
