As the development of electronic IT, course of study of world machine tool already entered the Electromechanical unifinication period that is core with digitlizing production technology, among them numerical control machine tool represents one of products namely. Numerical control machine tool is the machines master and national economy main base of manufacturing industry. It is national economy each branches provide equipment and measure, have the economy of infinite enlarge and social effect. Main shaft is numerical control machine tool an important part in forming, machine efficiency to rising, enlarge machines material limits greatly, promotion machines quality to having main effect. The system of main shaft drive that uses transducer construction can come true without extremely timing, have timing range wide, the structure is simple, the advantage such as managing cost, use on the machine tool very general. Hai Pumeng is special HD30 series transducer relies on a gender with its superior performance and Gao Ke, in the application of numerical control machine tool the respect obtained exceedingly good result. The technology asks drive of main shaft of numerical control machine tool is the main component of numerical control machine tool, have demand of the following technology to drive system: Can come true to add decelerate quickly: Count those who charge a machine tool to increase slowdown time normally the requirement is shorter, control in 1~2s commonly, because this is right the dynamic performance demand of transducer is higher. Need has powerful overload capacity when low speed: Requirement transducer has reliable overload to protect a function. Enough torsion output can offer when low speed: According to the working characteristic of numerical control machine tool, system of drive of general requirement main shaft can output 150% rated torsion in 1~2Hz. Firm fast precision is tall: To the main shaft electric machinery that high speed rotates, speed wave motion crosses a general to be able to affect the treatment quality of workpiece, the rate stability demand to drive system is very accordingly high. Interface is convenient: Machine tool of ordinary numerical control controls moving command to come from terminal to give, frequency gives an instruction to come from imitate quantity, because this asks,transducer has the terminal that match and imitate quantity interface. HD30 vector controls vector of series of HD30 of transducer brief introduction to control general transducer is Shenzhen city sea the new generation vector that limited company of science and technology of Pu Meng spy develops controls transducer, have capacity of low speed torsion strong, control precision is tall, exceed Jing Yin to run control. Inside buy process PID, but curve of quantity of process designing imitate, 16 paragraphs multistage fast move, logistic but process designing input outputs terminal, much frequency gives the characteristic function such as passageway design, organic ground links the personalized demand current requirement and industry user rise, offerred tall compositive unifinication solution. Have very strong electrified wire netting and environment to get used to ability at the same time, reliability is high, the operation goes to the lavatory simply. Basis of HD30 series transducer the technical demand of system of drive of main shaft of numerical control machine tool, have advantage of numerous specific aim: 1.
Have reliable ground overload to protect ability, can output 150% above reliably rated output electric current exceeds 2 minutes of;nextpage2.
0.
Torsion starts to be able to achieve 180% above when 5Hz, satisfy the demand;3 of big torsion of low speed of drive of machine tool main shaft.
The imitate quantity of at least two standards inputs interface (AI1 voltage 0~10V, AI2 voltage / electric current is optional - 10V~+10V/0~20mADC) , can accuse systematic interface with most number compatible, versatility strong;4.
Use newest algorithm, make imitate measures an input to have tall degree of linearity and pinpoint accuracy;5.
Output terminal is logistic but process designing. Be like,can output 0 fast signal, the signal in movement, speed arrives at signal, breakdown directive, contented system the monitoring;6 to position of main shaft career.
55KW and type of power social estate is all under its inside buy apply the brake is unit, need not again outside distribute unit of apply the brake. 7.
1~16kHz of limits of carrier wave frequency, the effective howl that reduced main shaft system calls phonic;8.
Mark matchs RS485 communication interface, MODBUS communication agreement, debug software;9 with special PC.
Online identifying electric machinery parameter, the stability that assures a system and accuracy;10.
Voltage of electrified wire netting from adaptive control, averted the interference that voltage wave motion brings effectively. Among them DI1, DI2, DI3, DI4 parts set stays order of restoration of machine input, exterior breakdown for freedom of FWD, REV, terminal, AI1 gives a passageway as frequency. But process designing relay often outputs controller as breakdown relay. Epilogue of final parameter setting carries in machine tool sky (when machining a spare parts) below the condition, run rotate speed and deviation of set target rotate speed actually not to exceed 1RPM. When the machine tool machines a spare parts (actual torsion is equivalent to 80% electric machinery rated torsion) , rotate speed of cutting trends instant declines, through vector condition of control speed annulus falls, rotate speed restores quickly to give rotate speed deviation of rotate speed of around; actual measurement does not exceed 1RPM likewise. HD30 vector controls transducer to apply already successfully in drive of numerical control machine tool to dominate a field, its superior performance (low frequency torsion is big, timing range is wide, stable state precision is tall, add decelerate fast, the operation goes to the lavatory neatly, functional protection is full) and high reliability got sufficient test and verify, satisfy main shaft of numerical control machine tool completely to control.
