Ying Wei is vacated without series of CHE of speed sensor vector already research and development is successful

One, true vector controls transducer of series of CHE of 　 　 　 to use DSP to control a system, finish true not having speed sensor vector is controlled (open loop vector is controlled) , control photograph comparing with V/F, vector control has bigger advantage. 2, transducer of series of CHE of 　 of 　 of economy structure 　 is simple and easy model transducer, basically face client of form a complete set, can satisfy the functional requirement of major client. Function of functional module name brings clavier to realize this machine outside demonstrative independence clavier and outside keyboard makes outside the surveillant 　 LED of moving condition of the double control that makes keyboard and transducer: For simple and easy model clavier, all function 　 that can realize this machine clavier makes keyboard outside LCD: Offer Chinese to show, and inside embed parameter to copy a function quickly serial communication function provides RS485 physics communication MODBUSRTU and ASC Ⅱ embed inside interface function of terminal of mode of two kinds of communication offers rich terminal to control a function to offer user freedom to choose 　 　 3, 　 of 　 of 　 of main technique parameter 1, output frequency limits: 0.

00~600.

00Hz 　 　 2, speed controls fashion: The vector that do not have PG controls (SVC) , V/F controls 　 3, instruction passageway means: 　 of control of operation face plate, terminal, long-range communication control 4, frequency gives way: Keypad is given, imitate quantity is given (signal of electric current, voltage) , long-range communication is given, multistage fast give, PID closed circuit is given etc. 5, starting torsion is big: 0.

5Hz/150%(SVC) 　 　 6, limits of carrier wave frequency: 1.

0K ～ 15.

0KHz; 7, speed controls precision: ± 0.

5% top speed (SVC) ; 8, automatic voltage adjusts (AVR) : When voltage of electrified wire netting changes, can hold output automatically tension is constant 　 9, automatic current limliting: Can restrict the maximum of electric machinery electric current, protect transducer and electric machinery 　 reliably thereby 10, the control that place frequency: Curves of a variety of trigonometry wave frequency, the personalized demand 　 of contented spin industry 11, muti_function QUICK/JOG key: Can do muti_function key-press is used, a variety of applied requirement 　 of contented user 12, terminal of all inputs, output all is programmable, the use of convenient user 4, dependability designs 　 1, means of installation of radiator of independent air channel is whole set of design of air channel of whole set independence inside cabinet put oneself in another's position, outside cabinet put oneself in another's position optional, fan changes convenient, transducer is safeguarded simple and great raised transducer to be in the spin, printing and dyeing, chemical fibber, papermaking, dependability 　 that pulls silk, cement to make the applied environment that waits for an industry to differ fall to move for a long time 2, voltage of input of electrified wire netting of design of voltage of wide electrified wire netting is in - 15%~15% , transducer but safety moves, the user is beardless and other handle 　 3, 7.

Standard of transducer of series of 5KW above CHE deploys dc reactor to raise factor of output side power overall efficiency and the Gao Cixie wave that heat up stability to eliminate input side effectively are right the influence of transducer, the interference 　 that reduces pair of periphery 4, electrify of transducer of function of safe self check, the system undertakes system of complete safe self check undertake safe clamp down on to the modification of functional parameter and setting to soft, hardware, prevent an user to be opposite of functional parameter install 　 by accident 5, exceed strong protective function to be offerred for the user amount to 20 diversiform breakdown to protect a function, can come true to arrive from transducer electric machinery, to peripheral equipment all-around protection provides breakdown automatic restoration function, of convenient and groovy breakdown eliminate automatically inside buy be struck by lightning sheds protector too, rise effectively to protect functional 　 to the ego of inductive thunder 6, production platform of the standard has the craft of antistatic, anticorrosion, the 3 processing that prevent lacquer that prevents dust to specialization the manufacturing management system with water rigid product line CNC Milling
