The distance according to transducer and electric machinery can determine cable and wiring method

Advocate loop: The action of reactor is the Gao Cixie wave that prevents transducer generation the input loop that carries power supply returns electrified wire netting to affect other equipment getting report thereby, need decides to whether need to add reactor according to the capacity size of transducer; Filter is the installation output end in transducer, those who reduce transducer output is tall second harmonic, arrive when transducer when the distance of electric machinery is further, should install filter. Although transducer itself has all sorts of protection functions, but lack photograph protection not perfect however, breaker is in advocate overload rises in loop, lack equal protection, can undertake choosing according to the capacity of transducer when type selecting. The overload protection that can use transducer itself replaces hot relay. II.

Dominate return circuit: The hand that has labour frequency frequency conversion uses switch, so that be when frequency conversion occurrence breakdown can the hand moves the frequency that cut worker worker to move, because output end to cannot increase tension, solid is versed in frequency and frequency conversion want lock having each other. The distance of transducer of 　 of 　 of graph of transducer control principle and electric machinery decides cable and I of 　 of 　 of wiring method 　 .

The distance of transducer and electric machinery should as far as possible short. Reduced the right electric capacity of cable so, reduce the emission source of interference. II.

Control cable chooses screen cable, dynamical cable chooses screen cable to perhaps use screen of the canal that wear a line entirely to electric machinery from transducer. III.

Electric machinery cable should take a line at other cable independently, its are the smallest the distance is 500mm. Should avoid parallel of electric machinery cable and other cable Sunday run to take a line at the same time, such ability reduce transducer to output the electromagnetism that voltage changes quickly and arises to disturb. If control cable and across of power source cable, answer to make they press across of 90 degrees of horn as far as possible. The imitate quantity line that concerns with transducer and advocate loop line takes a line apart, although be in control ark,also want such. IV.

The imitate line that concerns with transducer had better choose screen double skeining thread, the 3 core cable that dynamical cable chooses screen (the cable old files that its norms wants to compare common electric machinery) or the user manual of comply with transducer. The transducer of 　 of ground connection 　 of transducer is correct ground connection is to increase systematic stability, restrain the important step of noise ability. The Yue Xiaoyue of ground connection resistor of the earthing terminal of transducer is good, of ground connection lead sectional do not be less than 4mm, length does not exceed 5m. The ground connection of transducer should nod departure with the ground connection of power plant, cannot in all. The screen layer one aspect of the matter of line receives the ground connection of transducer to carry, float of other one aspect of the matter is empty. Electric gas phase is connected between transducer and control ark. (original title: The distance of transducer and electric machinery determines cable and wiring method) CNC Milling CNC Machining
