9300 product information
Integrated technologies
The integrated technology function forms a vital part of the
intelligent drive solution. The 9300 servo inverter series
comprise four software variants in identical hardware devi-
ces:
- 9300 servo
- 9300 register control
- 9300 cam profiler
- 9300 positioning control
All four variants are equipped with a uniform user interface.
The respective technology function can be set quickly and
easily. In detail:
9300 inverter
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 controland without overlay gearing.
109300 cam profilerMechanical cams can be found quite frequently in production machinery. Changing or modifying the productcauses lengthy and complicated set-up procedures. The 9300 servo cam profiler can store up to 8 differentcam profiles, so that cam profiles can be switched withoutdelay 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 foropening and closing of welding bars a function has beenintegrated in order to achieve constant welding periods at variable clock frequencies.9300 positioning controlPositioning made deceptively simple. The 9300 positioningcontrol includes a complete position controller withsequence control. Easy commissioning with only few inputvalues is a modern solution as compared with externalposition controllers and their complicated programminglanguage. Responses from limit switches or other drivescan be evaluated at the same time. If the initial position ofthe product is tainted with considerable tolerances, thetarget position is reliably found by automatic materialcorrection.Lenze
