SIMOVERT MVSystem descriptionOpen- and closed-loop control functions2The field-oriented Vector Controlis used for the motor-sideclosed-loop control of theSIMOVERT MV voltage DC linkdrive converter.The Vector Control can eitherbe operated as closed-loopfrequency, speed or torquecontrol.The Vector Control achievesthe same dynamic performanceas that of a DC drive.This is made possible by thefact that the torque- and fluxgeneratingcurrent componentsare precisely controlled,independently of one another.Specified torques can be preciselymaintained and limitedusing this vector control.In the speed control range 1:10,the field-oriented control of theSIMOVERT MV does not requirea speed encoder and isessentially independent of themotor parameters.A speed encoder is required forthe following SIMOVERT MVapplications:¦ High requirements are placedon the dynamic performance¦ Closed-loop torque control/constant-torque drives with acontrol range > 1:10¦ Lowest speeds¦ Highest speed accuracy.The various control versions arelisted in detail on Page 6/9.Closed-loop control features¦ Message system where plaintext messages are output onthe OP7 operator panel¦ Self-diagnostics of the controlhardware, e.g. memorytest¦ Multi-channel fast tracememory to record currentsand voltages for drive diagnostics¦ Non-volatile memory for reliablediagnostics, even if thepower supply fails¦ HV-IGBT modules are monitoredwith an individual signalfor mounting slot¦ Comfortable local operatorcontrol via the OP7 operatorpanel¦ Highly accurate and stableactual value sensing usingthe innovative sigma-deltatechnique for reliable driveconverter actual values (referto Fig. 2/7).Fig. 2/7Actual motor currents and output voltages are precisely sensedusing a special, patented sigma-delta techniqueSoftware functionsThe basic software includes abroad scope of standard functions.These functions offermaximum ease of use and outstandingflexibility. Also, theyensure universal operatingconditions and a high degree ofoperational reliability andsafety.Setpoint inputSetpoints can be entered as thesum of main- and supplementarysetpoints as follows:¦ Internally: as fixed, motorizedpotentiometer- or jog setpoint¦ Externally: via the analoginputs, the serial interfaces orthe option modules.The fixed internal setpoints andthe motorized potentiometersetpoint can be changed-overor set from any of the interfacesvia control commands.Automatic restart(option L32)This function automaticallyrestarts a drive converter whenthe power returns after a shutdown due to power failure.Restart-on-the-fly circuit(option L31)The restart-on-the-fly circuitallows the drive converter to beswitched to a motor which isstill rotating.2/6 Siemens DA 63 · 2004
SIMOVERT MVSystem descriptionOperator control and diagnosticsSIMOVERT MV drives can becontrolled and visualized at thedrive converter itself, or alsoexternally.OP7 operator panelThe SIMOVERT MV drive canbe locally controlled and monitoredusing the operator panelin the cabinet door.The assignment of the keys isdefined by the drive converter’ssoftware for open-loop andclosed-loop control. The followingfunctions can be selected:¦ Display drive actual values¦ Enter speed setpoints usingthe numerical keys¦ Read and delete messages¦ Preset two motor and setpointdata records¦ Preset jog setpoints¦ Menue-assisted functions forservice and commissioning.At the unit via¦ the standard OP7 operatorpanel¦ a PC with the Drive ES engineeringsystemBy entering the necessaryparameters, the control modecan be set from remote todirect.The following actual values canbe displayed:¦ Speed¦ Motor voltage¦ Motor current¦ Motor output¦ cos j of the motor¦ DC link voltage¦ Operating timeThe messages and actual valuesare displayed on a liquidcrystaldisplay with 4 x 20digits. The plain-text display isin one of the following languages(as standard):¦ German¦ EnglishRemote control via¦ the control terminal strip¦ PROFIBUS DPFig. 2/8OP7 Operator panel2Control terminal stripThe drive converter includes acontrol terminal strip to controland monitor theSIMOVERT MV drive from acontrol room. Both analog aswell as digital inputs andoutputs are available at thiscontrol terminal strip (refer toPage 6/10).PROFIBUS DPSIMOVERT MV is equipped asstandard with a PROFIBUS DPinterface to establish the couplingbetween the drive and thehigher-level automation system.Today, PROFIBUS DP isthe standard bus system forSiemens drive technology for allapplications at the field level.PROFIBUS DP is specified inthe European StandardEN 50170, Volume 2, andpermits cyclic data transferbetween the SIMOVERT MVunits and the higher-levelsystem.In order that the drive can fulfillthe specific process task, itsparameters must be individuallyadapted during the commissioningphase. The Drive ESBasic engineering tool is usedfor this purpose. The programallows the drive parametersto be handled in a structuredfashion when commissioningthe drive and when service isrequired. Drive ES communicatesdirectly with theSIMOVERT MV via theconnected PROFIBUS DP.Fig. 2/9Mounting rack with vector controlSiemens DA 63 · 2004 2/7
