Be aimed at compact model of numerical control lathe and milling machine brand-new drive plan

2011, the compositive, driver Sinamics S120 Combi that can apply extensively at groovy lathe and milling machine puts a height on the market. This driver is compositive a power source module, electric machinery module that is used at electric machinery of drive main shaft, two electric machinery module that are used at drive feed electric machinery to 3 (latter power is relatively inferior) . Driver has 6 kinds of type optional, but the application that its application can cover machine tool of numerical control of half odd axis almost. In the numerical control lathe that the development setting of compositive type driver produces in the whole world and milling machine, the main shaft power that has an in part almost is under 14 KW. Simple numerical control lathe deploys two geometry axis only normally (X axis and Z axis) with a main shaft, because module of these 3 electric machinery is OK,drive makes stage lathe. Also can provide cutting tool of a power sometimes on a few simple lathe, extremely individual situation falls to still can deploy servo knife tower or rear push frame. Anyhow, go up in groovy lathe module of 6 electric machinery is enough. Simple milling machine deploys 3 geometry axis normally (X axis, Y axis and Z axis) with a main shaft, because module of these 4 electric machinery is OK,drive makes station milling machine. Axis of additionally two geometry also can be deployed sometimes on milling machine (A axis and C axis) , module of below this kind of circumstance 6 electric machinery is OK and contented use. To machine tool of groovy numerical control, mix power source module 3 become an unit to collect of module of 4 electric machinery, it is first-rate drive plan. This unit still has expansibility, can drive is additional arrive two geometry axis (graph 1) . Driver of compositive type of – of graph 1 Sinamics S120 Combi, design to final user character in the light of harsh industrial environment and weak electrified wire netting, what advantage does driver of this kind of compositive type have after all? The dominant position of compositive type driver is relative the module type drive that at be being mixed by independent power source module electric machinery module makes, in the light of structure of groovy machine tool custom-built compositive type driver has an advantage this kind more. When Xi Menzi is developing drive of Sinamics S120 Combi, discharged the interface between module, optimized the structure of driver. To OEM, this means installation to use dc generatrix simplier to join no longer at the same time, because this OEM throws control,the time of ark design is able to shorten. Of interface disappear the durable sex that still increased drive at the same time. Driver of compositive type of Sinamics S120 Combi is not simple ground general book Sinamics S120 " bale " together, be in however with an as parallel as installed surface circuit board go up to arrange all package with first-rate means, these component are OK drive is all axis. Accordingly, compare with photograph of long and narrow module type component, the contact between the power semiconductor in compositive type driver and radiator is more close together. radiator of the type that wear a wall installation is when control ark is exterior (namely so called exterior and cooling) , in-house loss can fall to lowest, need not take extra in-house and cooling step to controlling ark thereby, this kind of means but managing cost. On driver of Sinamics S120 Combi, in-house loss takes total loss 15% to 19% , and go up in component of the book with 50 wide millimeter S120, in-house loss is occupied about 50% . Mix besides power semiconductor the contact between radiator is much better outside, of the height of driver and width than be being mixed almost of radiator identical, this kind of dimension also makes come loose hot effect is much better. Choose appropriate power source voltage, reduce loss besides in-house loss lower outside, the power source module of Sinamics S120 Combi used a course to reform " intelligent type " control, because the Die of total meritorious service of this driver also is reduced somewhat, be in especially blame be fully loaded with mode to fall. With book driver, sinamics S120 Combi also is designed in the light of 480 V of – of 3 AC 380 V of power source voltage. Compare with photograph of equipment of 3 AC 200 V, it can reduce the loss of 20% at most. The country is used in the mainest machine tool in (graph 2) , basically give priority to with the electrified wire netting of 480 V of – of 3 AC 380 V. Graph electrified wire netting of 2 whole worlds distributings: Although be in the electrified wire netting of easy wave motion, also should ensure the voltage of generatrix of dc of safe power supply of controller and driver is taller, the upright voltage on electric machinery is taller also, because this can reduce the loss of electric machinery further. With the Xi Menzi that Sinamics S120 form a complete set uses electric machinery can be on all power source voltage under 3 AC 480 V move. Former the transformer of equipment of 3 AC 200 V needs no longer, because this reduced loss further. In addition, with book equipment, sinamics S120 Combi also can feedback second birth electric energy wire back net. Little, installation is covered an area of to be simple on the machine tool with compact structure in Nextpage control ark, how the space in managing control ark especially important. Besides improving equipment measurement (tall X wide X is deep: 380 millimeter [millimeter of X 304 of millimeter of 1] X 260) outside, how as far as possible managing wiring space also is crucial. In view of this element, the power connector of Sinamics S120 Combi is located in in the starting a hole of equipment front bottom, outside the ventilated span that such power cable maintain 80 Mm besides need, there is span demand no longer on height. Additional, because connector is operated more easily, wiring is more convenient also. Return even inside equipment compositive have EMC screen terminal, discharged exterior screen (graph 3) . Graph 3 compact and durable driver, compositive Sinamics S120 Combi of EMC screen terminal undertook reforming in the light of exterior and cooling means, but in when necessary it is OK also and whole installation is controlling cabinet interior, the installation frame of use form a complete set can be installed. The advantage of exterior refrigeration is control remain only inside ark 15% to the loss quantity of heat of 19% , major quantity of heat sends out control ark is exterior. Because this controls the power of ark refrigeration unit to be able to be reduced greatly, a simple heat exchanger is normally enough, and need air conditioning no longer (graph 4) . Graph 4 Sinamics S120 Combi installs means: In-house or control ark is exterior, depend on usable space and cooling plan only the fan module with 86 tall millimeter is located in equipment coping. And consolidate board combination uses the exterior and cooling program that can offer complete set for OEM, OEM need not design more fixed head again. Face a requirement the design Sinamics S120 Combi of abominable workshop is to be aimed at harsh manufacturing environment to develop. The span between carbon fin is wider, can get in order to prevent the pollution of dirt, refrigerant and lubricant. Fan is located in equipment coping, because this can adhere to no longer,condense in the lubricant on carbon fin. Fan gives wind force to be able to amount to 290 M3/h, greatly the 160 M3/h that prep above asks actually. Fan of this kind of large wind force can blow the eyewinker on carbon fin on one hand, also can drop the difference in temperature between equipment coping and coping effectively on the other hand, prolong equipment life thereby. Fan is designed in the light of high temperature environment, although be below the high temperature of C of 70 ° ,life still can amount to 35000 hours. Fan defends grade is IP54, electron yuan parts of an apparatus is horniness pouring makings. Bearing uses Nirosta ball bearing, although fall in the environment that is full of lubricant oily mist,also can work reliably. Fan function by driver monitoring, when fan is out of order driver can give out early-warning clew user, right now the user still can continue to machine. Besides fan, equipment of whole platform Sinamics S120 Combi also is designed for high temperature environment. Accordingly, when the temperature inside control ark achieves 55 ° C, equipment still can move. Won't appear even when temperature achieves C of 45 ° fall look. In-house fan gets likewise monitoring, avoid equipment interior occurrence heat source, avoid to electroanalysis capacitor shifts to an earlier date desiccate. All circuit of Sinamics S120 Combi board gush has protective lacquer, ensure equipment is below tall wet environment and harmful gas atmosphere still hard usage. Still can move in abominable electrified wire netting besides ambient conditions, the country uses in a few main machine tools in (for instance: China and Indian) , quality of electrified wire netting is very crucial also. What India uses is electrified wire netting of 3 AC 415 V TT, do not set the electrified wire netting that protects the land namely, optimal protection protects switch implementation through odd electric current. Be aimed at this condition, sinamics S120 Combi has the design of low discharge electric current. Fall in this kind of environment at the same time, power source filter may reduce manufacturing efficiency, accordingly the design of Sinamics S120 Combi still should get used to those who do not have filter to move. In addition, india is returned often power cut (a day of power cut attributes normal phenomenon 10 times) , single-phase voltage pelter or three-phase voltage pelter, and whether source of rapid extensive telegram in reply to rectification IGBT from oscillation diode special key. Special hard usage used on Sinamics S120 Combi accordingly from oscillation diode. Additional, the control course of power source module is optimized, appear only when the breakdown of critical hardware, power source module just can be shut. Accordingly, equipment can be on two-phase power source brief move, and won't shut instantly. In the Asia, the acuteness wave motion of voltage of electrified wire netting is to use manostat normally (Servo Voltage Stabilizer, SVS) will stabilize. Manostat is a motor type actually from Ou transformer, can adjust with ± 100 V the voltage inside a day is poor. In the beginning of Sinamics S120 Combi is designed, considered the combination with this equipment. Its function also gets actual test and verify on Indian manostat. Compositive design, but do not break flexibility to be on lathe of a few groovy standards and milling machine, need otherwise to stop sometimes module of two electric machinery. Accordingly, withheld on Sinamics S120 Combi long the dc generatrix join of experience card, can join fully most module of two S120 book compact electric machinery. Accordingly, driver of compositive type of Sinamics S120 Combi also acceded the partial flexibility of module pattern book S120. When module of join S120 book compact electric machinery, whole installation is controlling this module cabinet is inner, although the radiator of S120 Combi is installed,controlling ark exterior. On module of small-sized electric machinery, the impact of loss power is very little. 6 kinds of model are configured basically for goods Sinamics S120 Combi but drive arrives 3 times 4 feed axis, 6 kinds of model offer money (next watches) . The size that 6 kinds of model of driver of compositive type of Sinamics S120 Combi express all model is same [1, 2] . Xi Menzi offers the compact book under 18 A S120 patulous module. Rated commutate power is 16 KW or 20 KW, can provide enough abundant amount for patulous module. Sinamics S120 Combi can be mixed with Sinumerik 828D system of numerical control of 840D Sl BASIC is ideal cooperate to apply. CNC Milling
