The version of 1 above just can use program of user of echelon picture authorized strength, we use S7-200 to regard process designing as the tool. In CD dish tool box (Tool Box) in deployed " PLC802 file library " , included subprogram library among them, and give standard lathe and milling machine configured process designing example respectively, accordingly, use rising is handy more. As a result of transformed machine tool for standard milling machine, example makes the process designing that wants pair of its milling machine only in using a process a few simple ground are revised and expand the PLC program that can complete a need. In the subprogram, had a definition respectively according to different function, basically include PLC-INI (systematic initialization) , EMG-STOP (stop processing urgently) , MCP-802D (the I/O condition of deferent Control Panel arrives interface) , AXES-CTL (each reference axis is controlled) , LUBRICAT (mensurable and time, lubricant control) , COOLING (cooling control) etc. The following problem should note in applied process. (1) in example program in stopping processing piece urgently, did not end to process of electrify of power source module (PO-END: M130.
7) the circumstance that answers process existence delay time to what #T-72 prepares to finish becomes a consideration. In debug we discover, this defer time is actually objective going up is existence, the accident of time because of the function of power source module different, if do not make delay time, the processing that calls the police to stopping urgently encounters the likelihood the trouble, often need to be pressed for many times repeatedly " RESET " key ability makes power source module prepares normally, stop ability urgently to call the police cleared. In view of safe consideration, we pursue in echelon lieutenant general " RESET " often shut bit of series connection to go to those who make can end a point from the back, after normal electrify, press " RESET " the time that key holds proper, finish the normal preparation of power source module smoothly. Of course, also can increase a delay time directly or define to reserve key is added at the back of what make can be finished. (2) in PLC program, the set that among them one block involves MD14510 will decide the logic that is lathe or milling machine concerns, of the pitch on in example program is lathe, the place should be done be adjusted appropriately and revise, otherwise the partial function of Control Panel cannot be used, we come up against Z axis to cannot move when use, only axis of X, Y can move. (3) MCP of SIEMENS 802D system board lathe edition and milling machine edition are general, OK when the way that defines each axis bolts oneself are defined neatly, rod of uses Z of program of milling machine example / negative to define for diagonal. Of 4 main shaft debug system of Xi Menzi 802D to function of imitate main shaft it is the imitate that dominates SIMODRIVE 611UE closed circuit module output is outputted as set point, and coder interface (- X472) be worth an input actually as TTL. Right now, digital feed axis is used at the set value of imitate main shaft as changeover axis, we just are with bus line address " 12 " X axis regards changeover as the axis. As a result of us this second transform use common three-phase to communicate asynchronous electric machinery need not coder feedbacks, it is set of MD30200 of main shaft parameter to needing without the imitate main shaft of direct coder " 0 " . In addition, the model of the transducer that we use is the device of An Chuan frequency conversion of CIMR-G7A4015. (1) the hardware join of 611UE and An Chuan transducer shows 2 times like the graph: (2) use those who had done " driver debugs cable " the X471 of individual PC and 611UE join rises, through SimoCom U of driver debugging aids the concerned parameter to X axis driver and setting have a definition (according to debug manual to operate) , store and restoration. (3) to transducer power transmission, try to move an operation to issue moving electric machinery in the hand, test the stand or fall of transducer and electric machinery; Next, detect automatically below mode of self-study be used to each parameter of electric machinery, after waiting for transducer to be saved automatically, change transducer menu operation pattern. (4) NC side is main main parameter set is worth the set of functional parameter as follows: 13060=0 (bus line address is 12) ; 13070=8000H; 30134=2; 30110=1; 30120=2; 30220=0; 30230=2; is special those who mention is parameter 13070 ten million cannot forget set, can appear otherwise cannot call the police clearedly information is: "26015 DRIVE-TELEGRAM-TYPE P915 INVAILD " , and function still not become effective. In addition, if be MD30120 setting by accident " 1 " appear possibly still " 2001 PLC stops " call the police, at the same time PLC stops to move. The acquiescent value of the relevant parameter that checks imitate interface is: "MD32250=100; MD32260=3000 " . No hurry first the imitate voltage that adjusts imitate interface, start a machine tool afresh, function of its imitate main shaft already become effective. Main shaft of test run imitate, the signal that confirms imitate voltage and statement of travel of have a change of luck of positive and negative is not had to choose a site for the capital by accident. If run the rate of standard of speed short of of electric machinery, answer to adjust imitate interface through MD32250 and MD32260. In the process that tries electric machinery, we discover the set-point of imitate voltage has 3 only greatly most.
4V left and right sides, this test electric machinery is rated speed is 1440r/min, next executive instructions all are MDA means " M03 S1440 " , revising parameter MD32250 and MD32260 in debugging a process, get the data of a few groups of tests of following watches. Voltage of corresponding imitate of MD32260144014402000300010005003000 of main shaft of MD322505010010010010010050 of main shaft of object name data (unit: V)1.
84 from on the test data of the watch can see the pattern, in give instruction of same rotate speed to fall, 32250 set are worth parameter (effective limits: 0~100) bigger, the imitate voltage that give out will be bigger; 32260 set value exceeds parameter big, the imitate tension that give out is less. Captured this one rule to be able to be finished smoothly to the adjustment of imitate voltage. In debugging a process, it is advisable that the imitate voltage that should give out electric machinery should give out electric machinery in the correspondence when top rotate speed presses a value to adjust 10V. Come here, main shaft adjusts a function to be finished basically. 4 last word classics are transformed, the dependability of this machine tool and can safeguard a gender to get rising greatly, machine tool precision also got ameliorative. Whole transform a process, investment cost little, quality tall, yield results is quick the accord that waits for outstanding characteristic to get authority reputably. Use of the machine tool as scheduled, alleviated in time the manufacturing pressure of the factory, brought good economic benefits for the enterprise. CNC Milling
