7 Preface and general informaion 1.2 Lenze sofware guidelines for variable names The previous conceps for Lenze conrollers were based on codes ha represened he inpu and oupu signals, and he parameers of funcion blocks. For he sake of clariy, names were defined for he codes in he documenaion. In addiion, he signal ypes were defined by graphical symbols. The user could see a a glance which kind of signal (analog, phase angle ec.) had o be presen a he paricular inerface. The concep for he new auomaion sysem does no use direc codes in he programming. The IEC sandard is used insead. This sandard is based on a srucure of variable names. If he user applies variables in his projec, hen he can name he variables as he chooses. In order o avoid he growh of a muliude of differen convenions for naming variables in exising and fuure projecs and funcion libraries ha are programmed by Lenze personnel, we have se up sofware guidelines ha mus be followed by all Lenze saff. In his convenion for creaing variable names, Lenze keeps o he Hungarian Noaion ha has been specifically expanded by Lenze. If you make use of Lenze specific funcions or funcion blocks, you will immediaely be able o see, for insance, which daa ype you mus ransfer o a funcion block, and which ype of daa you will receive as an oupu value Hungarian Noaion These convenions are used so ha he mos significan characerisics of a program variable can insanly be recognized from is name. Variable names consis of a prefix (opional) a daa ype enry and an idenifier The prefix and daa ype enry are usually formed by one or wo characers. The idenifier (he "proper" name) should indicae he applicaion, and is herefore usually somewha longer. Prefix examples prefix a p Meaning Array (combined ype), field Poiner l Lenze9300Servo.lib EN

If an idenifier is assembled from several "words", hen each "word" mus sar wih a capial leer. All oher leers are wrien in lower case. Examples: Array of inegers anjogvalue[10] ; Bool bisempy ; Word wnumberofvalues ; Ineger nloop ; Bye bycurrenselecedjogvalue ; Recommendaion for designaing variable ypes In order o be able o recognize he ype of variable in a program according o he name, i makes sense o use he following designaions, which are placed in fron of he proper variable name and separaed from i by an underline sroke: I_<Variablename> Q_<Variablename> IQ_<Variablename> R_<Variablename> C_<Variablename> CR_<Variablename> g_<variablename> gr_<variablename> gc_<variablename> gcr_<variablename> VAR_INPUT VAR_OUTPUT VAR_IN_OUT VAR RETAIN VAR CONSTANT VAR CONSTANT RETAIN VAR_GLOBAL VAR_GLOBAL RETAIN VAR_GLOBAL CONSTANT VAR_GLOBAL CONSTANT RETAIN Example for a global array of ype ineger ha includes fixed sepoins (analog) for a speed seing: g_anfixsespeedvalue_a 1 4 Lenze9300Servo.lib EN 1.1 l

9 Preface and general informaion Designaion of he signal ype in he variable name The inpus and oupus of he Lenze funcion blocks each have a specific signal ype assigned. These may be: digial, analog, posiion, or speed signals. For his reason, each variable name has an ending aached ha provides informaion on he ype of signal. Signal ype Ending Previous designaion analog _a (analog) digial _b (binary) Phase angle difference or speed _v (velociy) Phase angle or posiion _p (posiion) Tip! Normalizing o signal ype phase angle difference/speed: (INT) rpm Normalizing o signal ype analog: % value under [C0011] = n max Normalizing o signal ype angle or posiion: moor revoluion Examples: Variable name Signal ype Type of variable nin_a Analog inpu value Ineger dnphise_p Phase signals Double ineger bload_b Binary value (TRUE/FALSE) Bool ndigialfrequencyin_v Speed inpu value Ineger Special handling of sysem variables Sysem variables require special handling, since he sysem funcions are only available for he user as I/O connecions in he conrol configuraion. In order o be able o access a sysem variable quickly during programming, he variable name mus include a label for he sysem funcion. For his reason, he name of he corresponding sysem block is placed before he name of he variable. Examples: AIN1_nIn_a CAN1_bCrlTripSe_b DIGIN_bIn3_b l Lenze9300Servo.lib EN

23 Special funcions Supply failure conrol (L_MFAIL) Fine seing of he supply failure conrol For he fine seing, you will have o repea he following poins several imes. 1. Obain a very low final speed wihou he conroller reaching he undervolage hreshold LU: Increase he proporional gain nvp. Reduce he inegral acion ime ntn. 2. Avoid acivaion of he brake uni or he overvolage hreshold: Increase he inegral acion ime ntn unil he characerisic in Abb is almos reached. If necessary, also reduce he sepoin of he DC bus volage a ndcse_a (in he example C0472/19 ( FCODE_nC472_19_a )). 3. An increase of he run down/deceleraion ime or reducion of he brake orque (see Abb. 2 12) is only possible wih resricions: Increasing he acceleraion ime nti reduces he iniial brake orque and simulaneously increases he deceleraion ime. Increasing he inergral acion ime ntn reduces he iniial brake orque and simulaneously increases he deceleraion ime. If he inegral acion imes are oo long, he conroller reaches he LU hreshold before zero speed is reached. The drive is hus no longer under conrol. 4. Re esablish any signal connecions which may be required o he oupus of he drive conroller (erminals X6). Noe! Use C0003 o save all seings im a parameer se, if hey are o be reained on power off.

24 Special funcions Supply failure conrol (L_MFAIL) Rese of he supply failure conrol The supply failure conrol is rese wih brese_b = TRUE (in he example, hrough X5/E5 (when DIGIN_bIn5_b is conneced o brese_b ). The rese pulse is always required if: The resar proecion is acive. The resar proecion is used and he supply (supply or DC supply) was swiched on Resar proecion The inegraed resar proecion is o avoid a resar in he lower speed range, afer he supply volage was inerruped for a shor ime only (supply recovery before he drive has come o sandsill). Esablish he resar proecion ( 2 9: Parameerizaion of he example in Abb. 2 10) In C0472/18 ( FCODE_nC472_18_a ), ener he hreshold in [%] of n max (C0011) below which no auomaic sar is waned afer supply recovery. If he speed a supply recovery < hreshold in C0472/18 ( FCODE_nC472_18_a ): he drive will sill be braked under conrol. This funcion can only be ended by brese_b = TRUE. If he speed a supply recovery > hreshold in C0472/18 ( FCODE_nC472_18_a ): he drive acceleraes o is sepoin along he se ramps. The funcion is deacivaed by: nthreshold_a = 0%. A rese is made by brese_b = TRUE This is required afer every supply (re)connecion, and is shown by bsaus_b = HIGH, when bfaul_b = FALSE. Noe! To be able o make he seings hrough he sysem block (SB) FCODE, you mus also have used he free codes of he SB FCODE Dynamic adapaion of he conrol parameers In special cases, a dynamic modificaion of he proporional gain may be useful. Two inpus are available for his purpose a FB L_MFAIL ( ncons_a and nadap_a ). The resuling proporional gain resuls from: ncons_a nadap_a V p nvp 100% (100 % 16384) 2 14 Lenze9300Servo.lib EN 1.1 L

25 Special funcions Supply failure conrol (L_MFAIL) Fas supply power recovery (KU) The fas supply recovery causes a resar of he conroller, unless he resar proecion is acive. The drive acceleraes o is sepoin. If his is no waned, you can delay he resar by wreriggertime or preven i in combinaion wih he resar proecion. A fas supply recovery occurs: Due o he sysem, he supply recovery is indicaed by he supply failure deecion via he level of he DC bus volage. ( 2 7) because of a "shor inerrupion" (KU) of he uiliy company (e.g. in a hundersorm). Because of fauly componens in he supply cables (e.g. slip rings) So se wreriggertime > he measured deceleraion ime ha can be achieved in braking operaion Applicaion example Drive nework wih digial frequency coupling Sop! Für drive neworks which are conneced via digial frequency (a maser and one or more slaves): he supply failure deecion and conrol mus only be acivaed for he maser. You mus link he supply failure conrol ino he signal flow o mee his requiremen. You mus operae all he conrollers hrough he erminals +U G, U G in a DC bus configuraion.
