7KW/50Hz/380V, choose transducer model to be Q9000-C-0344, 300W/120ohm of resistor of apply the brake. Transducer FIV/0V terminal provides speed imitate amount to numerical control system, FIV receives imitate of numerical control system to measure interface signal, 0V receives negative signal, signal is signal of 0-10V imitate voltage, control main shaft rotate speed. FWD/REV/CM is transducer turning / invert signal terminal, give out by numerical control system normally turning signal FWD perhaps inverts REV comes drive auxiliary relay, of auxiliary relay often open contact to receive transducer FWD/GND or REV/GND, the positive and negative that controls lathe main shaft thereby turns. Control system parameter debugs: The process is adjusted in parameter in, ought to notice: 21-01 parameter, choose advocate frequency instruction, the setting is inputted for imitate signal 0-10V (1) ; 21-02 parameter, moving instruction chooses, the setting is control loop terminal (1) ; 51-04, highest output frequency chooses, the correspondence output at the transducer when imitate signal 10V is inputted frequency, because be inside 0-3000rpm limits timing, consideration machinery reduces speed ratio, this this parameter can be installed for 107HZ; 36-01 installs carrier wave frequency according to electric machinery nameplate; 31-01 and 31-02 are quicken time 1 with slowdown time 1, according to the client's requirement, 31-01=5S, 31-02=5S; 11-02 is the option that controls fashion, choose vector control, 11-02=2. What need an attention particularly is, because vector controls need to offer electric machinery parameter (impedance) , the detailed parameter that supplies electric machinery to transducer according to the nameplate of electric machinery so (rated voltage / rated electric current / rated frequency / rated rotate speed / number of electric machinery pole) , pass the moving key on position operator, transducer can move automatically. In running a course automatically, give electric machinery parameter besides computation beyond, still can detect clean carries electricity, these a few parameter can make vector control shows higher performance, let electric machinery develop the greatest potential, when undertaking parameter teachs oneself be used to, be sure to want to be in carry for nothing (load is not received on electric machinery axis) when undertake. When carrying for nothing only ability assures to teach oneself the accuracy of the electric machinery parameter that be used to comes out, learn the time that the process can last ten seconds oneself. Test and move: The frequency that outputs in constant torsion paragraph (0-50Hz) , vector pilot carries electric current to have VF pilot in part only almost for nothing, the electric current when load is a few smaller than VF also; And when laden cutting, VF control has apparent speed to drop in initial stage, and idling speed and laden speed have greater poor value. And opposite Yu Shi measures control, although initial stage of main shaft rotate speed also can have drop, but drop the value is lesser, and speed is met pick up very quickly, final idling speed and laden speed differ is not apparent. Above the course debug, with VF control is compared, function had very big improvement, no matter from carry electricity for nothing, low speed moment of force, still be the change of speed, the effect is very apparent, can satisfy the requirement of numerical control machine tool completely. After investment moves, use result is satisfactory, the application in showing transducer of series of cruel horse Q9000 to control a system in lathe main shaft is successful. CNC Milling
