1 make unitly as main shaft can signal. The locomotive way of device of partial main shaft gives signal by speed, control of negative pole sex, can turning main shaft at this moment signal uses as main shaft makes can be controlled, main shaft inverts signal need not. Controller of partial main shaft has speed to arrive with 0 fast signal, can use main shaft speed to arrive from this with main shaft 0 fast inputs, implementation PLC runs to main shaft the monitoring of condition. 2.

Main shaft speed is controlled China in HNC-21 passes the imitate in interface of XS9 main shaft to measure output controallable main shaft rotate speed, the output range that estimates when main shaft imitate is - 10V ～ + 10V, use at bipolar driving unit of main shaft of speed instruction input or transducer, use at this moment make can of signal control main shaft open, stop. The output range that estimates when main shaft imitate is 0 ～ + 10V, with the main shaft driving unit that inputs at instruction of odd polarity speed or transducer, use main shaft to turning at this moment, main shaft inverts of signal control main shaft, invert. The number that the value of imitate voltage sends corresponding interface by user PLC program measures a decision. 3.

Join of main shaft coder passes XS9 of main shaft interface but outside receive main shaft coder, use at whorl cut, tap to wait, china in the coder that device of HNC-21 numerical control can receive kind of two kinds of output, differ minute of TTL square wave or square wave of odd polarity TTL namely. Use the coder that need branch commonly, the dependability that ensures long transmission is apart from and increase interference rejection capacity. China in if the hookup of device of HNC-21 numerical control and main shaft coder pursues 1 is shown. Graph the hookup of device of 1 numerical control and main shaft transducer (if do not have main shaft coder criterion the content in dotted line casing is done not have) 5.

The join example of numerical control device and main shaft device (1) when with electric machinery of common three-phase asynchronous join uses the communication asynchronous electric machinery that does not have timing device to regard main shaft as electric machinery, need to use numerical control device to output switch to measure control auxiliary relay and contactor only, controallable of main shaft electric machinery turning, invert, stop, if pursue,2 are shown. Graph 2 in electric machinery of control of KA3, KM3 is turning, KA4, KM4 controls electric machinery to invert. Graph the join Nextpage of device of 2 numerical control and electric machinery of main shaft of common three-phase asynchronous China in the join of device of HNC-21 numerical control and electric machinery of main shaft of common three-phase asynchronous, can cooperate main shaft machinery to shift gear timing of solid existing level, still but outside receive main shaft coder to realize tap of screw cutting treatment or tigidity. (2) with communication join of frequency conversion main shaft uses communication transducer to dominate electric machinery of communication frequency conversion, the infinitely variable speeds of main shaft can come true inside certain limits, the main shaft that needs to use numerical control device at this moment controls interface (XS9) medium imitate quantity voltage outputs signal, the speed that serves as transducer is given, use switch to measure output signal (XS20, XS21) control main shaft is opened, stop (or, invert) . China in the hookup of device of HNC-21 numerical control and main shaft transducer is like graph 3-13 place to show. When using main shaft of communication frequency conversion, because low speed is characteristic very not ideal, need to cooperate machinery to shift gear to be mixed with character of low speed of give attention to two or morethings commonly timing scope. When needing turning whorl or tap, but outside receive main shaft coder. (3) with servo drive main shaft join uses servo drive main shaft to be able to acquire wider timing range and good low speed character, still can realize main shaft directional control. The main shaft that can use numerical control device to go up controls interface (XS9) medium imitate quantity outputs signal (imitate voltage) , as main shaft unit speed is given; Use PLC to output control to open, stop (or, invert) reach directional. China in if the hookup of device of HNC-21 numerical control and main shaft servo pursues 3 are shown. Graph when the hookup of device of 3 numerical control and main shaft servo needs turning whorl or tap, the information of main shaft position that can use feedback of itself of main shaft servo to give interface of numerical control device XS9, if the graph is shown 4 times; Also but outside receive main shaft coder, if pursue,5 are shown. Graph the hookup of device of 4 numerical control and main shaft servo -- positional feedback comes from main shaft servo pursue the hookup of device of 5 numerical control and main shaft servo -- positional feedback comes from exterior coder CNC Milling
