Summary: ? Regret is troubled by Tao to mast transducer of ICROMASTER440 of Shu ancienting name for a water catltrop is in the application on the machine tool, reach its to carry the news report between PROFIBUS-DP and SIMATICS7315-2DPLC and SIMATICHMIOP270. Keyword: MICROMASTER440 transducer PROFIBUS-DP one, the foreword rapid development as Chinese economy, in recent years coloured metallurgy industry also gets rapid development, a lot of new plants are cast build, old plant is timely also transform, the demand that because the society is right,at the same time specific power consumption, environmental protection takes seriously more and more and manufacturer reachs product quality to manufacturing technology is higher and higher, the ability of environmental protection product of high quality, high accuracy improves product quality and productivity, the equipment that reflects a business is advanced, automation control level is high, level of management is high. Electric control uses this milling machine equipment of complete set SIEMENS: It is control core by SIEMENSS7-315-DPPLC system, each site uses news report of PROFIBUS-DP bus line, controller of motion of control SIMODRIVE611universal servo / servo electric machinery and MICROMASTER440 frequency control implement / frequency conversion electric machinery, fulfil the automata function of whole product line by technology measure, according to craft the requirement dominates the harmony between aircrew and action. Undertake through SIMATICHMIOP270 interactive. Realized equipment high accuracy, easily pilot advantage, achieve international advanced level. This equipment belongs to domestic head stage to abstain research and development, replaced abroad to import a product, this type equipment needs to be imported from abroad before this. The article basically introduces the MICROMASTER440 transducer control that is based on PROFIBUS-DP communication. 2, systematic introduction asks according to craft, electric drive chose this machine tool feed of implementation of bit body of drive of 12 MICROMASTER440 transducer and driver of 17 SIMODRIVE611universal servo and displacement, pass SIMATICHMIOP270: Collect an user setting and modification parameter data, detect status of indication unit work (the position, electric current, rotate speed) , provide breakdown information, call the police record inquiry, real time monitoring, each site uses news report of PROFIBUS-DP bus line. Regard control as core by SIMATICS7315-2DPPLC. Transducer of Xi Menzi MICROMASTER440 is general-purpose the delegate of the most advanced product in transducer, apply to all sorts of gearshift gearing, software function is rich, configuration is agile. This machine tool that be not mark uses treatment carbon element of cathode piece, use at electroanalysising electrobath of aluminous factory build by laying bricks or stones. Groovy face need is smooth, such treatment come out to should assure its surface roughness what carbolic piece uses at groovy face at the same time, need abrade technology. 12 MICROMASTER440 transducer is used at respectively thick mill, nick, ditch, abrade wait for working procedure. Cent of mode of operation is automatic, semi-automatic use 3 kinds of pattern with the hand, should curium rate of mill aircrew automation is high, those who have one key operation is full automatic change a function, increase the labor strength of the productivity, member that reduce field work greatly. 3, control system forms SIMATICS7315-2DP and transducer of MICROMASTER440 of its I/O module 7. 5KW/18.
Communication of 5KW/37KW accessary PROFIBUS-DP board SIMATICHMIOP270SIMODRIVE611universal servo driver is accessary PROFIBUS-DP communication board systematic hardware configures as follows: 4, moving principle and function: MICROMASTER440 transducer uses roll of drive bit body on this machine tool, the different bit body rotate speed that machines stuff place requirement is different, this asks to the treatment of different batch the product chooses different milling career, the recipe can be done in HMIOP270, because the product model of the product still is done not have,can come down finally certainly, and model mixes the demand product as the market to change ceaselessly, so the rotate speed of bit body is inputted from OP270 temporarily. PROFIBUS is current one of levels of current spot bus line on international, the high speed data that is used at spot layer is deferent. Advocate the station is read periodicly take the input news from the station periodic to send output message from the station. The communication between SIMATICS7315-2DPPLC and MICROMASTER440 transducer comes true by PROFIBUS-DP bus line, MICROMASTER440 transducer and SIMODRIVE611universal servo driver serve as from the station. SIMATICS7315-2DPPLC reads the control word that writes MICROMASTER440 transducer and condition word with systematic function FC14/FC15, the control that realizes pair of MM440 and monitor. Through SIMATICHMIOP270 user the user can set MM440 parameter, obtain breakdown information, inquiry to call the police record. Apply SFC14/SFC15 to read the program of give typical examples that writes MM440 to be as follows: Control system composition writtens guarantee composition of a picture is as follows: 5, of transducer basically debug parameter the following with among them 18.
5KW electric machinery is exemple: 6, because bit body is inertial,application is experienced bigger, MM440 does not have unit of adscititious apply the brake and resistor of apply the brake, breakdown F0002 appears when jockeying at first, increase P1121 of brae decay time, extend time of apply the brake this problem gets settlement. Overall for apply MM440 transducer this very successful, timing, start, function of apply the brake is very good. The user is very satisfactory also. MM440 transducer software is very rich, provide BICO interconnection function, use very convenient. CNC Milling
