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
