Of machine tool of numerical control sculpture advocate transmission system uses infinitely variable speeds mostly. Current, system of infinitely variable speeds basically has system of frequency conversion main shaft and system of servo main shaft two kinds, use dc or electric machinery of communication main shaft commonly. Rotate through taking transmission to drive main shaft, or through bringing the decelerate gear inside transmission and main shaft box (in order to obtain bigger torsion) drive main shaft to rotate. Because range of timing of main shaft electric machinery is wide, but stepless speed regulation, make the structure of winner axle box simplifies greatly. Compare as a result of the tall sex price of transducer to the client at present, so transducer is used on the machine tool very general. Ying Wei vacates transducer of CHE series vector with its distinctive function and superior sexual value are compared, rise abruptly quickly on the application of numerical control machine tool gradually. Numerical control system shows 1 times like the graph: Graph 1   system is main   of   of performance demand   (1) wave motion of the speed inside total rate limits is small; (2) low speed moment of force is large, can assure cutting of low rotate speed; (3) the time that increases decelerate as far as possible short. The system is main   of   of functional requirement   (1) control means choice is controlled for V/F; (2) need terminal control regards a command as the source, terminal of two lines type controls: FWD moves to turning (S1 is inputted) , REV turns over have a change of luck to go (S2 is inputted) ; (3) frequency source measures set for imitate (computer control plate outputs 0 ~ 10VDC) , need to input frequency instruction from AI1 mouth only; (4) moving rotate speed is in commonly 0 ~ 21000r/min, the running frequency of conversion transducer is 0 ~ 350Hz (electric machinery of 2 class high speed) ; (5) quicken and slowdown time basis client oneself demand, be in commonly 3~5s, compare because of the rotate speed that move tall, so need takes the transducer of unit of apply the brake; (6) need breakdown outputs signal (Y is outputted) with breakdown restoration signal (S3 is inputted) . Electric wiring is like transducer of   of systematic specification   the graph is shown 2 times. Graph AI1/GND terminal offers 2   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. S1/S2/COM is transducer turning / invert signal terminal, give out by numerical control system 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.
