【正文】 acterized by thehighest operational reliability and availability worldwide, in thewidest range of industrial sectors. Whether as main drives forprinting machines, as traversing and hoisting drives in cranes,as elevator and cable railway drives, for applications in therubber and paper industries, as shear drives in the steel industry,as rolling mill drives, winder drives, cutterslitters or profilingmachines and dynamometers for motors, turbines or gearbox test stands.In these and as in many other applications SIMOREGDCMASTER are extremely ?exible and cost effective:SIMOREG DCMASTER 6RA70 are fullydigital, linemutated of variablespeed DC motors. The rated DC current, speci?ed onthe equipment rating plate (maximum permissible continuous DC current) can be exceeded up to times in operation. The maximum overload time depends on the overload current characteristics and the preload condition of the drive converter and is drive conver ter specific. Because of an integrated parameterizing device, the drive units are autonomous and no additional programming or measuring equipment is required to parameterize them. All of the functions of the openloop and closedloop control for the armature and ?eld circuits are realized in two highperformance 16bit converters which are connected to threephase line supplies. They are used to control the armature and ?eld circuits.Engineered Low Voltage ACConverterSIMOVERT MASTERDRIVESTop solutions With engineered drivesThe SIMOVERT MA STERDRIVES Vec tor Control frequency converters are Voltage source DC link converters with fully digital technology and IGBT inverters which, in conjunction with Siemens three phase AC motors, provide highperformance,economical drives for all industrial sectors and applications. All SIMOVERT MASTERDRIVES share a consistently uniform the whole power range, the units (converters,inverters) and system ponents (recti?er units, braking units)have a uniform design and a uniform connection system. They can be bined in many ways and arranged side by side to match every possible drive requirement. Being system modules,they can be used to create the most suitable drive system,whether this involves single drive or multimotor drive systems.The mercial viability of the drive system from the customer39。s point of view is of prime concern to the Siemens39。 development engineers potential that our application experts can make the most of: on an individual basis for every single it is consultancy, planning, missioning or just an initial enquiry. You can always rely on us. For example, in matters of expertise, where EMC safety, AFE systems or efficient water cooling are particularly in demand you will find we have the required knowhow and engineering skills.Cabinets and system configurations for power output ranges from ~5000kW can be created to match speci?c customer requirements, with either aircooling or watercooling in our application workshop.By Siemens famous drives supplier From new SINAMICS drives family Stands for the latest drives technologyHigh quality cabinet equipment(1)Cabinet equipment ensure high quality of whole drives system。(2)Compact design save space 30%~70%(3)RITTAL cabinet。(4)All Siemens low voltage ponents inside。(5)Human pretection design as standard。(6)Quiet operation by low noiseHigh perfermance control technology New control board CU320 Intelligent designCF card for software storage, optical interface for connections, etc. Variable control mode availiable V/F control Sensorless vector control Close loop vector control (with encoder) high dynamic perfermance torque increase time less than 2ms PID controller insideMore available as standard Input reactor as standard for all G150 less than 500kW EMC ?lter (2nd class) as standard Unique prehensive operation panel AOP30 as standard Pro?bus interface as standard Customer terminal TM31 as standardMore prehensive consideration Complete options to optimize drives system Unique software tools for missioning, energy saving caculation, etc.More visible bene?t energy save with G150QualitySinamicsG150, the high performance converter cabinet for single drive application is produced in line with international production standards and process, with the highest reliability, usability and functionality.The whole process, from development, design, production, to the logestic including order processing and supply center, all are certi?ed by DIN ISO G150 is the new low voltage AC converter. It can bring visible energy saving, applied to all single drive application. It also can meet different load requirements including constant torque and varialbe torque.High Performance LV AC Converter for Single DrivesSINAMICS G130An excellent priceperformance ratio The SINAMICS G130 drive converter has been pletely newly developed and distinguishes itself as a result of its cost effectiveness and simplicity in every phase of the product lifecycle. This extends from planning and procurement through mounting amp。 installation and missioning up to daytoday operation and G130 offers an excellent price performance ratio and can be integrated in any automation solution.100 % line supply voltage at the motor— without any secondary effectsUp until now, voltage source DC link converters used two main techniques to generate a variable output that bines the advantages of the two techniques mentioned so called edge modulation withoptimized pulse patterns means that the line supply voltage is available at the motor terminals at 100% load–and more speci?cally, without any secondary effects such as extremely high harmonics and supplementary losses in the motor. The converter losses are also lower.Performance and features: Simplicity: rapid type selection, simple operation and easy maintenance Ingenious design: quiet, modular desig
