G9 series transducer uses 4G9 series transducer advanced magnetic flux controls a technology, electric machinery is when low speed torsion is big, speed precision is tall, the price is reasonable, the function is all ready, have processing of twinkling power cut and speed to dog restart function, ensure the system realizes successive moving mechanism, in order to make sure electric accident turns in highest efficiency condition, accordingly, use G9 high-powered transducer to replace servo of main shaft communication, it is choice of first-rate of machine tool industry. If pursue,1 is shown. Graph Nextpage of sketch map of system of 1 numerical control (1) the volume of characteristic introduction · of G9 transducer is minor, belong to confuse you model product, take up means of control of lesser; · is control ark space sine wave SPWM, control function relatively the improvement that the VF previously controls means to very great performance goes up, satisfy the requirement of machine tool main shaft on low speed torsion especially, torsion starts to be able to reach range of frequency of carrier wave of · of 100% above; when 5Hz 0 ～ 16kHz, the · of electromagnetism noise; that reduces electric machinery offers imitate of 0 ～ 10V to measure interface, can accuse systematic interface with most number compatible, capability of overload of · of versatility strong; is strong, rated output electric current exceeds 150% above one minute; · provides muti_function output terminal signal, for example unusual signal, the signal in movement, speed arrives at signal, breakdown directive, automatic to the monitoring; · of position of main shaft career torsion compensates contented system, main shaft of contented machine tool machines demand in what low speed circumstance falls. (2) debug environment and wiring, debug methodological client to select distribution engine for 3.
0kW/50Hz/380V, choose transducer model AMB-G9-3R7-T3B, Ω of 400W/150 of resistor of apply the brake, see a picture 2. Graph the terminal of applied transducer VS/GND on numerical control machine tool offers 2 transducer to be measured with imitate of speed of numerical control system, VS receives imitate of numerical control system to measure interface signal, GND receives negative signal, signal is signal of voltage of imitate of 0 ～ 10V, control main shaft rotate speed. S1/S2/COM is transducer turning / invert signal terminal, give out by numerical control system normally turning signal perhaps inverts signal, come drive auxiliary relay, of auxiliary relay often open contact to receive transducer S1/S2/COM, the positive and negative that controls transducer thereby turns. Parameter is installed as follows: LF005 and F006 are quicken time and slowdown time, according to the client's requirement, f001=5S, f002=1S;lF030 and F031 are installed according to electric machinery nameplate, f010=9A, f031=1;lF012 upper limit operates frequency choice, the correspondence output at the transducer when imitate signal 10V is inputted frequency, because be to be inside limits of 0 ～ 2000rpm timing, will mechanical decelerate calculates than this after going in, this parameter needs to install 66.
7Hz;lF002 parameter is locomotive signal and frequency origin set, the setting is controlled for outside terminal signal (3) . (3) debug electric machinery of result main shaft to introduce drive of G9 high-powered transducer, satisfy treatment requirement, prolong the service life of cutting tool. As a result of adoption banner magnetic flux algorithm, although be in low rotate speed (low frequency) move fall to also can output the torsion of 100% smoothly, in order to satisfy the treatment need of different spare parts, can replace structure of traditional scroll bearing main shaft completely, and structure of this main shaft is simple, compact, OK the stepless speed regulation with true implementation. The rotate speed of this main shaft measures signal to control output frequency by exterior imitate, craft is machined in what differ (wait like; rough machining, finish machining) the rotate speed with different need, the imitate that can differ by output of numerical control system right now measures voltage signal to give transducer, realize different rotate speed, open at the same time stop signal to also be controlled by numerical control system, raise automation rate! Main shaft of machine tool of numerical control of 5 last words communicates vector of brand of servo, entrance to control transducer and frequency conversion commonly special electric machinery, purchase cost transducer of series of An Bangxin G9 of very tall; is compared with its distinctive function and superior sexual value, rise abruptly quickly on the application of numerical control machine tool, the client that is machine tool industry reduces the cost cost of about one times, and reliability is high, create more benefit for the client.
