8A, rated rotate speed: Mechanical drive of of 970r/min compares: 1: 1.
of 5 processes data: of 45# steel checks function index actually: Main shaft rotate speed: 15Hz of 200r/min(transducer running frequency is controlled) feed function and 2)5 of of speed .
Parameter of electromotor of of of lathe of 5kW numerical control: Rated power: 5.
5kW, rated frequency: 50Hz, rated voltage: 380V, rated electric current: 13A, rated rotate speed: Mechanical drive of of 1400r/min compares: 1: 1.
of 5 processes data: of 45# steel checks function index actually: Main shaft rotate speed: 200r/min(transducer running frequency 9 ~ 10Hz) and main shaft rotate speed: 22Hz of 450r/min(transducer running frequency is controlled) transducer of series of ED3000 of uses transducer of feed function and series of ED3000 of of speed 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 ED3000 high-powered transducer to replace servo of main shaft communication, it is choice of first-rate of machine tool industry. The volume of introductory of characteristic of transducer of 1) , ED3000 is minor, belong to confuse you model product, take up means of control of of 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 of of 100% above; when 5HZ 0 ~ 16KHz, the of of 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 of of versatility strong; is strong, rated output electric current exceeds 150% above one minute of; provides muti_function output terminal signal, for example unusual signal, the signal in movement, speed arrives at signal, breakdown directive, the automatic torsion of of of monitoring; to position of main shaft career compensates contented system, the 2) of of of of of treatment demand; that main shaft of contented machine tool issues in low speed circumstance, debug environment and wiring, debug client of methodological to select distribution engine for 3.
0KW/50Hz/380V, choose transducer model to be AMB-ED3000-3R7-T3B, resistor of apply the brake 400 tile / 150 ohm. AI1/GND terminal offers transducer to be measured with imitate of speed of numerical control system, AI1 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. FWD/REV/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 FWD/REV/COM, the positive and negative that controls transducer thereby turns. Parameter installs as follows: 1)F005 and F006 are quicken time and slowdown time, according to the client's requirement, f001=5S, 2)F030 of of of F002=1S; and F031 are installed according to electric machinery nameplate, f010=9A, upper limit of 3)F012 of of of F031=1; 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. Parameter of 4)F002 of of of 7Hz; is locomotive signal and frequency origin set, the setting controls 5) of of of; for outside terminal signal, debug electric machinery of main shaft of result to introduce drive of ED3000 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 numerical control machine tool communicates vector of brand of servo, entrance to control transducer and frequency conversion commonly special electric machinery, purchase cost transducer of series of ED3000 of easy drive 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.
