PLC uses S7-300 to input / output module, the PROFIBUS interface that uses system of 840 numerical control at the same time is added install 13 S7-ET200BPLC module (among them) of module of two imitate output, build 4 long-range control to assign a station. This interface number is according to transmitting speed 1.

5Mbaudrate, outclass X122 interface 187.

The transmission speed of 5Kbaudrate, raised data to transmit speed. Xi Menzi is used between each minutes of station cable of special news report, have data news report with CPU, save control cable to use a measure namely so, also lowered electric fault rate. This machine tool still has function of dragon door axis to reach advocate - from the function (basically solve X1, XA1, synchronism of W1, WA1 moves) and function of 5 axes linkage, chinese shows, fixed loop of the standard, have the systematic function of 840D standard. The configuration of drive system and electromotor chose electromotor of system of drive of servo of number of Xi Menzi 611D and servo of 1FT6 series communication to transform X1 axis, XA1 axis, y axis, z axis, w1 axis, WA1 axis, s axis, choose module of number of Xi Menzi 611D to undertake controlling. PLC part chooses Xi Menzi S7 - 300 transform former S5-PLC with S7-ET200B. Use Control Panel of SIEMENS840D standard machine tool and user operation face plate to realize a few auxiliary movements of the machine tool and function. Setting of function of machine tool standard passes function of standard of basis primary machine tool above all, devise electric principle plan by oneself, organize field assembly to debug undertake PLC, NC debugging on-line. Through choosing ruler of HEIDENHAIN linear grating (LB382C) changes former Y axis, Z axis, W1 axis, WA1 axis surveys a system. The increment coder that uses HEIDENHAIN (ROD485) changes coder of buy of former X position of axle, main shaft is directional coder. Function of X axis synchronism uses 2 increment coder (ROD485) . The synchronism of two electromotor runs the rod of X1 of implementation of function of dragon door axis that uses 840D, XA1 axis. Function of W axis synchronism uses rule of LB382C linear grating (the left and right sides installs) of feet of a linear grating each. Use the function of dragon door axis of 840D, the synchronism of 2 electromotor runs implementation W1 axis, WA1 axis, set fine tuning electromotor to move what crossbeam level adjusts to use as the hand in WA1 side. The immediateness that the immediateness that main shaft basis installs on ram installs on switch and accessory milling head switch combination is different, adopt PLC to program, can undertake automatic, hand uses installation accessory milling head and different accessory milling head different power limitation, in order to protects accessory milling head not to exceed power to undertake workpiece cutting. Machine tool data deploys the door of numerical control dragon to a standard machining center, according to the machine tool real work need made data of the following machine tool configure. X1, XA1, y, z, w1, WA1, the NC parameter of S axis is configured; X1, XA1, y, z, w1, WA1, the drive parameter of S axis is configured; X1, XA1, y, z, w1, WA1, the drive of S axis is optimized; X1, XA1, y, z, w1, the pitch of WA1 axis is compensated. Operate a station to undertake hardware configuration to each users on the machine tool through PROFIBUS bus line online reach set.
