DSCU series digitlizes feed servo to control unit completely is limited company of system of Beijing spaceflight numerical control the form of word of new generation total number that the means development that cooperates through international gives communicates servo driver. This product has a technology precision of stable and advanced, reliable, control tall, function strong, bulk capability of small, interference rejection is strong wait for an advantage, reached the advanced level of foreign congener product. Good control performance makes the feed control that its can use at numerical control machine tool not only usable also dominate a field at needing to undertake high accuracy position and speed pilot move. 1. Product characteristic (1) introduces high-powered professional chip series, make processing capability of the system gets assuring adequately. (2) uses digital vector to control algorithm, control performance is high. (The character of high low speed with good 3) and system are rigid. (4) passes software setting, same servo can choose synchronous to communication electromotor or communication asynchronous electromotor to undertake controlling. (5) uses multiple protection and redundant design, product reliability is high. (Alternating current source of three-phase of 6) use 380V is immediate power supply, need not transformer, sexual price is compared tall. (7) interface rich, function all ready, operation is convenient. 2. 1 3 of watch of index of performance of main function index requesting an audience. Special function and its are used (limitation of 1) moment of force closes in certain and specific application field, if protection is in tensional control, pressure control,machinery and workpiece are not asked by attaint the moment of force that restricts electromotor output is worth normally, when the limitation that arrives at set when output moment of force is worth, pitching moment restricts a function to will act well. Function of pitching moment limitation controls fashion through parameter P22() , P305(moment of force restricts a cost) , exterior instruction inputs end " TLI " reach mouth of pitching moment imitate to input upright V2 to undertake installing. Parameter P22 defines as follows: P12_0: 1 -- by the operation board will receive concerted effort quadrature to limit a function, limitation of 305 set moment of force is worth parameter. 0 -- prohibit receive concerted effort quadrature to limit a function by operation face plate. P12_1: 1 -- by RS, 485 interface will receive concerted effort quadrature to limit a function, limitation of 305 set moment of force is worth parameter. 0 -- prohibit by RS, 485 interface will receive concerted effort quadrature to limit a function. P12_2: 1 -- input end by exterior instruction " TLI " will receive concerted effort quadrature to limit a function, limitation of 305 set moment of force is worth parameter. 0 -- prohibit inputting end by exterior instruction " TLl " will receive concerted effort quadrature to limit a function. By exterior instruction the input is carried " TLI " control is compared by operation face plate, RS, 485 interface control is preferential level is high. P12_3: 1 -- value of pitching moment limitation carries V2 to give by imitate mouth input. , 0 -- prohibit value of pitching moment limitation carries V2 to give by imitate mouth input. If pitching moment restricts a value to be given by imitate mouth, criterion the pitching moment limitation of 305 set is worth parameter invalid. If pitching moment restricts a value to be given by imitate mouth, criterion P12_0, P12_1, P12_2 must have 1 to be equal to 1 will control receive concerted effort quadrature to limit a function. Pitching moment restricts functional parameter to set give an example: The maintenance that robot clip supports workpiece ability installs parameter P12=4P305= moment of force to restrict a cost (N · M) . When torsion controls fashion, mechanical protection installs parameter P12=12 to input quadrature of the relay that carry V2 to give voltage. (2) parameter rectifies servo of feed of calm DSCU series to have the self-regulated that measures parameter of user of physical characteristic, automatic set automatically to rectify a function oneself, use this function to be able to undertake be rectifyinged automatically deciding to partial parameter, shortened greatly debug time. Automatic wither whole function can pass Vector(of servo monitoring software to deserve to send randomly) undertake operating. When self-correcting parameter, open Vector software, choose " Parameters " menu, click " Atotuning ' option can start self-regulated to rectify a function. The electromotor in adjusting a process moves with different speed and direction of rotation, atotuning of column of news of Device Status of Vector software interface will show state for maize Gao Liang, after making calm end oneself, atotuning Xiang Gaoliang shows condition disappears, electromotor stops to move. If servo has,call the police to adjust an operation to will cancel automatically oneself in adjusting a process oneself, the meeting on Vector software interface is shown call the police accordingly content. (The control object that parameter of 3) switch control differs to suit and contented and different control ask, servo driver needs to have different control character. In software of control of servo of DSCU series feed beforehand buy annulus of two groups of speed and parameter of positional annulus control, make servo control performance more superior. The control parameter that when using, asks to be able to have debugged character of two groups of different control respectively beforehand according to control, when need change controls character, can carry through RS485 interface or exterior instruction input " NT " the switch that has parameter group, achieve control requirement then. (Obligate of servo of feed of series of DSCU of 4) network function RS485 network interface, can have communication with monitoring software Vector not only through this interface and also can reach with other servo driver go up an orgnaization into network of bus line type, can join at most on every network 31 feed servo, network address from 1 ~ 31, network address the 0 current addresses that serve as servo, use with the operation face plate has communication, network address is undertaken installing by parameter P2. RS485 interface sets rate of 6 kinds of baud, can undertake choosing through parameter P3. Set give an example: Address of P2=20 servo network is rate of baud of communication of interface of 20 P3=5 RS485 to be defeated by a person to output for 115200bit/s (5) (I/O) interface was using circuit of symmetrical and two-way diode in circuit of interface of I/O of servo of feed of series of DSCU of negative logic function, lose a person / output form can is, negative logic, shed classics input namely / the electricity that exports end can have aleatoric way, do not accept the restriction of polarity of exterior power source, huge went to the lavatory of servo and system even the line. When using, should input / output end has enough electricity to shed outdated corresponding interface statement is valid. It is in order to input end exemple, , means of negative logic join is as follows: logistic (graph 1) : IC: Lose upright link with 24V power source. Input end: Carrying join with 24V power source. Negative logic (graph 2) : IC: Carrying join with 24V power source. Input end: Lose upright link with 24V power source. 4. Representative application (1) representative application mill of 1 one HX715 mill of machining center HX715 machining center is market mill, auger, boring, bore with a reamer, attack the function such as whorl the vertical mill at an organic whole machining center, this machining center deserves to have what can hold 20 knives at most is automatic library of the knife that change a knife, workpiece is achievable after holding clip the treatment of a variety of working procedure. This machining center deployed servo of feed of servo of main shaft of series of DSSU of a spaceflight and series of 3 spaceflight DSCU, use reach an experiment to prove spaceflight series servo reachs tigidity to attack the respect such as whorl to have good character in heavy cut, satisfy completely tall, intermediate the use requirement of numerical control machine tool.
