POSIDRIVE MDS 5000The universal servo inverterfor fully digital servo axes

THE FULLY DIGITALPOSITIONING AXISTHE FIRST COMPLETE SYSTEMFOR EFFICIENT AUTOMATIONWith the development of thePOSIDRIVE MDS 5000 servoinverter, STÖBER ANTRIEBSTECHNIK is launching a totalrevision of the hardware andsoftware for the servo system.STOBER EK synchronous servo motorwith digital absolute valuator(standard version)2The data communicationbetween the POSIDRIVE MDS5000 and the STOBER EDEK and EZ synchronous servomotors is now entirely digital.The main factor allowing rationalrealization of this fully digital servo axis lies in the developmentof fully digital absolute encodersat industrial-scale prices. TheSTOBER synchronous servo motors in the ED, EK and EZ seriesare equipped with these devices.Innovative softwaregenerationThe commissioning softwarePOSITool is based on a completely new, modular 3-layerarchitecture with ergonomicinterface design.An applications library with parameterization assistant and anadditional flexible graphics programming facility forms a successful bridge between custommade design and universality.This new system technologybrings to an end the era of overloaded and confusing operatingprograms from the pioneeringperiod of inverters.The benefits are obviousThis comprehensive and rationalslimming down of the systemresults in significant cost benefits for hardware, configuration,cabling, installation and commissioning.The close coordination of allthe STOBER servo componentsis clear from the example of theelectronic motor rating plate.Its data is used automaticallyin the parameterization of thePOSIDRIVE MDS 5000 servoinverter.

Multiple use by alternatecontrol of different servodrivesServo drives often go into actionat timed intervals. Typical examples of this are handling operations and format adjustments.Multimotor operation with onlyone POSIDRIVE MDS 5000servo inverter is suitable forthese applications.SoftwareThe POSITool software can manage up to four separate positionor speed regulated axes andcontrol them alternately.A smooth transition from axisto axis is guaranteed by thesoftware.Power and signal flows arecontrolled with correct timing.The axis management does notrequire additional softwarecomplexity in a primary control.Sequential operation without functional limitationIf four drives are used as endless axes with absolute encoders, the exact positioning is stillfree from rounding errors evenif the gear units have differentand non-integer gear ratios.The digital technologymakes it possibleFor the first time the inexpensiveand reliable axis changeoverapplication is available for unrestricted use on servo drives.Axis changeover switchThe POSISwitch AX 5000 external module has been developedfor connection of the digitallycontrolled synchronous servomotors. Actuation is just via theexisting encoder cables, without further operations.POSISwitch AX 5000ALTERNATECONTROL OF SEVERALSERVO DRIVES3

MODULARSOFTWARE ARCHITECTUREThis conflict of objectives hasbeen addressed by STÖBERANTRIEBSTECHNIK and Software Suite V5 developed as asolution. This suite includesthe commissioning softwarePOSITool, a comprehensivelibrary with standard applications, as well as the firmwarefor the inverter generation 5000.Instead of rigidly defined firmware with an endless numberof parameter variations the userhas a modern, ergonomicallydesigned operator irmwareSuiteThe rapid pace of developmentsin electronics is leading to continuous improvements and expanded functions, especially inservo inverters, and yet this isassociated with constant growthin user software complexity. Atrend which is in stark contrastto the demand for simpler andmore accurate usability.Scalable software architectureFor everydayTo configure a drive, the commissioning software POSITooloffers a library with typicalpreproduced basic applications.Here is a selection:쎲 Fast reference value쎲 Comfort reference valueSpeed or torque referencevalue (selectable)3 analog reference values16 fixed reference valuesMotorized potentiometerPID controller reference valueReference values scalable asabsolute or percentage value쎲 Command positioningPowerful single axis positioning control with commandinterface in accordance withPLCopen and the additionalfunction POSILatch. Positionmeasurements can then betaken on external signals(e.g. linear measurements)쎲 Motion block positioning쎲 Electronic cam functionConnection of up to 32 axesThe consistent project orientation of the modules is provingextremely effective.The parameterization work issupported by assistant functions.MODULAR HFor expertsFunctional housing designThe new, user programmablefirmware has been upgraded toinclude a graphics editor layerin conformance with PLCopen .An experienced or trained userwill find a variety of predefinedfunction blocks in various libraries. With these, basic applications can be modified or givenextra functions.As part of the STOBER EMCstrategy, all the housings in thePOSIDRIVE MDS 5000 seriesare made of galvanized sheetsteel. They shield against electromagnetic interference andthus increase the units' RFIimmunity and reduce interference emission.Extra serviceFor a completely new functionality requirement or for comprehensive adaptation of thebasic application, STÖBERANTRIEBSTECHNIK offers thisas "tailor-made applications"service.The front housing is made ofhigh-impact plastic and incorporates the operator keypad,display, LED indicators, Paramodul and RS232 interface,along with the slots for the optional boards and terminals.The same design plastic fronthousing is used for all the sizes.Other highlightsThe software scalability allowsoptimum adaptation of functionality and response time to theapplication. The cycle time forsetpoint processing dependsonly on the calculation of theactivated system modules andthe parameters.Complex applications can alsobe mapped on the same hardware platform without modifying the firmware.The STOBER POSISwitch AX5000 axis changeover switchis prepared for use on the software side. Up to 4 servo axeswith different functionalitiescan be controlled alternately.ParamodulPlug-in memory module fortransfer of all program and settings data.If a POSIDRIVE MDS 5000 hasto be replaced, the existingParamodul is simply plugged inagain to restart operations. Thefunctionality is retained withoutrestriction.This plug-in memory module isalso an ideal, immediately available tool for documentation updating of operating conditions.SYSTEM CONCEPT OF TOTAL MODULARITY4
