【正文】 ore before movement, will need the frequency changer to carry on to the electrical machinery monomer from the study, otherwise the frequency changer will not be able the normal work. Its concrete procedure is first the rated voltage, the nominal current, the nominal frequency, the rated revolution per minute, the PG card pulse number and the electrical machinery pole number input which records the electrical machinery data plate above to the frequency changer, then starts the frequency changer, causes the electrical machinery idling revolution, finally these values through from the study, after automatically calculate read in the frequency changer in the electrical machinery parameter. Therefore regarding these parameters, is not unnecessary to go artificially carries on the establishment. VS616G5 general frequency changer establishment like table 2 shows.Table 2 VS616G5 general frequency changer establishmentParametersAppellationSettingsInstructionsA100Display language options0EnglishA101Storelevel parameters4ADVANCEDA102Control options3PG Vector ControlB101Frequency mand selection0Digital input operationB102Run mand selection1Input from the outsideB103Choose to stop1Free sliding stopB104Reverse the prohibition of choice0Allow motor reversalC101Acceleration time 3s0Hz up to 50Hz timeC102Deceleration time3s50Hz down to 0Hz timeC201S Curve started to rise timeC202S curve of the pletion of Rise timeC203S Curve began to decrease timeC204S curve of the pletion of decrease timeC501ASR proportional gain setting5C502ASR Integral time setting1sD101Frequency mand 10HzThe main speed frequency valueD102Frequency mand 250HzThe frequency of the specific value of orders 2D103Frequency mand 36HzThe frequency of the specific value of orders 3E101Inverter input voltage set380VE104Highest inverter output frequency50HzE204Phase motorMotor nameplate on the PhasH101Multifunction input 1，Select terminal functions 33Multispeed mand 1H102Multifunction input 2,Select terminal functions 44Multispeed mand 2H305Multifunction Analog Input terminal function selection 161FDo not use Analog InputL601Action had to choose one moment of detection4the detection output cutL602Over torque detection level 1100%Vector Control has set PGL603Over torque detection time 11sL805Power output protection of choice1ValidL807Inverter output phase selection1Valid3 Control systems software designAfter the hardware system design pletes, in order to realize the optimized control, but also needs to use Simens STEP 7 specialized programming software to carry on the design to the double elevator linkage control procedure. Because the elevator control system is a person machine interactive control system in fact, therefore purely uses the sequential control or the logical control is cannot answer the purpose, but should use the stochastic logic control mode in the design. At the same time, because between trapezoidal chart interdependence very strong, the programming quite is plex, therefore in time double elevator coordinated control system software part, mainly uses modular the programming thought to carry on the to the elevator movement rule, established had/does not have the driver, the overhaul, the priority service, the fire prevention and so on four work ways. Below its establishment procedure mainly follows controls the rule:Two elevators both observe the collection to choose the rule, the soon calling signal first carries on the registration, to with elevator movement with to the calling signal replies one by one, after with and summons the reply to the instruction to finish the elevator to be allowed the automatic reverse forced for this, the elevator parallel operation also follows corresponding dispatch principle: In normal condition, when after elevator use, the second elevator took the busy ladder can first automatically rise to third awaits orders, the first elevator took the elevator awaits orders in a yet higher goal. When some station has the entrance hall calling signal, then the busy ladder starts the passenger immediately which and the direction detection moves meets this two elevators the instruction arrive because of the theater box in closes a door awaits orders, then should defer to the effective use the principle, execution mutually in turn segment. Originally acts as the busy ladder the elevator now namely to take the elevator uses, but originally took the elevator uses the elevator this time namely bees the busy ladder. No matter is the first elevator or the second elevator pauses the level station which finally anchors to await busy ladder on line, if its place above appears any direction the entrance hall calling signal perhaps its underneath appears to the under entrance hall calling signal, then pletes by the busy ladder in a week travelling schedule, but the elevator does not give the reply movement. But, if appears the upward entrance hall calling signal in busy ladder underneath, then starts out the movement by the elevator answering signal to receive a busy ladder under line, if its underneath appears any direction the entrance hall calling signal, then pletes by the busy ladder in a week travelling schedule, but the elevator does not give the reply movement. But, if appears in the busy ladder place above any is upward perhaps to the under entrance hall calling signal, then starts out the movement by the elevator answering signal to receive a elevator stops as a result of the breakdown moving, another elevator then automatically undertakes the plete movement duty, follows the single elevator the movement of is takes the first elevator or the second elevator, as a result of in the calling signal causes the elevator directio
