1 Preface and general information

1.1 About this Manual

This Manual contains information on the function blocks that are included in the function library LenzeDrive.lib for the Drive PLC Developer Studio.

 These function blocks can be used in the 9300 Servo PLC, Drive PLC and ECSxA

automation system.

 The function blocks are based on the functions that are available in the 9300 servo inverter

(V2.0).

In the Drive PLC Developer Studio (DDS) you make the basic settings for your drive application offline by using variables (in accordance with the IEC61131−3 standard) as aids for parameterizing the appropriate function blocks.

Via Global Drive Control (GDC) or the keypad you can then set the parameters for the required functionality of your drive application online by accessing the codes of the function block instances.

1.1.1 Conventions used in this Manual

This Manual uses the following conventions to distinguish between different types of information:

Variable names

are written in italics in the explanation:

 "The signal at nIn_a ..."

Lenze functions/function blocks

can be recognized by their names. They always begin with an "L_":

 "The FB L_ARIT can ..."

Program listings

are written in "Courier", keywords are printed in bold:

 "IF (ReturnValue < 0) THEN..."

Instances

For function blocks that have one or more first instances there are tables that describe the corresponding codes:

Variable name L_ARIT1 L_ARIT2 Setting range Lenze

byFunction C0338 C0600 0 ... 5 1

You can access these codes online with Global Drive Control (GDC) or keypad.

Tip!

You can use the Parameter Manager to assign the same codes to these instances that are assigned in the 9300 servo inverter (V2.0).

Preface and general information

1.2 Lenze software guidelines for variable names

The previous concepts for Lenze controllers were based on codes that represented the input and output signals, and the parameters of function blocks.

 For the sake of clarity, names were defined for the codes in the documentation.  In addition, the signal types were defined by graphical symbols.

The user could see at a glance which kind of signal (analog, phase−angle etc.) had to be present at the particular interface.

The concept for the new automation system does not use direct codes in the programming. The IEC 61131−3 standard is used instead.

 This standard is based on a structure of variable names.  If the user applies variables in his project, then he can name the variables as he chooses.

In order to avoid the growth of a multitude of different conventions for naming variables in existing and future projects and function libraries that are programmed by Lenze personnel, we have set up software guidelines that must be followed by all Lenze staff.

In this convention for creating variable names, Lenze keeps to the Hungarian Notation that has been specifically expanded by Lenze.

If you make use of Lenze−specific functions or function blocks, you will immediately be able to see, for instance, which data type you must transfer to a function block, and which type of data you will receive as an output value.

1.2.1 Hungarian Notation

These conventions are used so that the most significant characteristics of a program variable can instantly be recognized from its name.

Variable names

consist of

 a prefix (optional)  a data−type entry  and an identifier

The prefix and data−type entry are usually formed by one or two characters. The identifier (the "proper" name) should indicate the application, and is therefore usually somewhat longer.

Prefix examples

prefix Meaning

a Array (combined type), field p Pointer

Examples of the data−type entry

Examples of a data−type Meaning

b Bool by Byte n Integer w Word dn Double integer dw Double word s String f Real (float) sn Short integer t Time un Unsigned integer udn Unsigned double integer usn Unsigned short integer

Identifier (the proper variable name)

 An identifier begins with a capital letter.  If an identifier is assembled from several "words", then each "word" must start with a capital

letter.

 All other letters are written in lower case.

Examples:

Array of integers anJogValue[10] ;

Bool bIsEmpty ;

Word wNumberOfValues ;

Integer nLoop ;

Byte byCurrentSelectedJogValue ;

1.2.1.1 Recommendation for designating variable types

In order to be able to recognize the type of variable in a program according to the name, it makes sense to use the following designations, which are placed in front of the proper variable name and separated from it by an underline stroke:

I_<Variablename> VAR_INPUT Q_<Variablename> VAR_OUTPUT IQ_<Variablename> VAR_IN_OUT R_<Variablename> VAR RETAIN C_<Variablename> VAR CONSTANT CR_<Variablename> VAR CONSTANT RETAIN g_<Variablename> VAR_GLOBAL gR_<Variablename> VAR_GLOBAL RETAIN gC_<Variablename> VAR_GLOBAL CONSTANT gCR_<Variablename> VAR_GLOBAL CONSTANT RETAIN

Preface and general information

1.2 Lenze software guidelines for variable names

1.2.1.2 Designation of the signal type in the variable name

The inputs and outputs of the Lenze function blocks each have a specific signal type assigned. These may be: digital, analog, position, or speed signals.

For this reason, each variable name has an ending attached that provides information on the type of signal.

Signal type Ending Previous designation

analog _a (analog) digital _b (binary) Phase−angle difference or speed _v (velocity) Phase−angle or position _p (position)

Tip!

Normalizing to signal type phase−angle difference/speed: 16384 (INT) ¢ 15000 rpm

Normalizing to signal type analog: 16384 ¢ 100 % ¢ value under [C0011] = n

Normalizing to signal type angle or position: 65536 ¢ 1 motor revolution

H G F E

Examples:

Variable name Signal type Type of variable

nIn_a Analog input value Integer dnPhiSet_p Phase signals Double integer bLoad_b Binary value (TRUE/FALSE) Bool nDigitalFrequencyIn_v Speed input value Integer

1.2.1.3 Special handling of system variables

System variables require special handling, since the system functions are only available for the user as I/O connections in the control configuration.

In order to be able to access a system variable quickly during programming, the variable name must include a label for the system function.

For this reason, the name of the corresponding system block is placed before the name of the variable.

Examples:

AIN1_nIn_a

CAN1_bCtrlTripSet_b

DIGIN_bIn3_b

Layout and definition of the special characters

The FB enables the definition of 7 special characters. It is possible to assign an individual ASCII code to each of these special characters.

 The 5 x 7 matrix of a character is defined via the array variable abyCharMap. Each array

element of data type byte is bit−coded and represents one column of the matrix (0 = white pixel, 1 = black pixel).

 The array variable abyCharCode is used to define the ASCII codes for the special characters.

Example:

Define a "" as second special character under ASCII code "200":

abyCharCode[1] = 200

Fig. 2−65 Example: Defining the matrix of a special character

The following figure shows the assignment of the array index to the matrix column:

Note!

The FB L_FWM of function library LenzeDrive0201.lib has been revised and can be used for the following Lenze PLCs:

If the FB L_FWM is used from older LenzeDrivel.lib versions, it should be replaced or only be used after consultation with Lenze!

The FB L_FWM is used to transmit error messages to the PLC. In this way, a TRIP, FAIL−QSP, message or warning can be triggered in the PLC while the PLC program is running.

The fault number that is transmitted is stored in the history buffer of the PLC (C0168/x).

Note!

Each FB instance may only be called once! If you need the FB L_FWM several times, create the corresponding number of FB instances.

 If the program includes several instances of the FB L_FWM which are of the same fault type,

then only the first fault of this fault type that is detected will be recorded.

 If several faults with a different response occur at the same time, only the fault whose

response has the highest priority will be recorded in the history buffer: – TRIP (highest priority)  message  FAIL−QSP  warning (lowest priority).

 Only edit L_FWM() in a task.  If byTypeOfFault has an invalid value, then the value 0 (TRIP) is used for byTypeOfFault.  If the value of wFaultNumber < 400, then the value 400 is used for wFaultNumber, if

wFaultNumber > 999, then the value 999 is used for wFaultNumber.

2.7.4 Speed preconditioning (L_NSET)

 When the controller inhibit (CINH) is set, the ramp generator accepts the value at nCInhVal_a

and passes it on to the following function. This function has priority over all other functions.

 bRfgStop_b = TRUE:

– The ramp generator is stopped. Changes at the input of the ramp generator have no effect

on the output signal.

 bRfg0_b = TRUE:

– The ramp generator decelerates to zero along its deceleration ramp.

 It is also possible to load the ramp generator online with a defined value. For this bLoad_b

must be set = TRUE. As long as this input is set, the value at nNSet_a is accepted by the ramp generator and provided at the output.

2.7.4.5 S−ramp

A PT1 element is connected to the linear ramp generator. This arrangement implements an S−ramp for an almost jerk−free acceleration and deceleration.

 The PT1 section is switched on/off with bSShapeActive.  The time constant is set with nTiSShaped.

2.7.4.6 Arithmetic operation

The arithmetic module makes an arithmetical combination of the main setpoint and the additional setpoint. The arithmetical combination is selected by byArithFunction.

2.7.4.7 Additional setpoint

 Via nNAdd_a you can combine an additional setpoint (e.g. a correction signal) with the main

setpoint.

 Via bNAddInv_b you can invert the input signal, before it is applied to the ramp generator. The

ramp generator has a linear characteristic. Its Ti−times are set with dnTirAdd (ramp−up time) and dnTifAdd (ramp−down time).

 If bLoad_b = TRUE, the ramp generator is set to 0 and held there, without considering the

Ti−times. The same applies when controller inhibit (CINH) is set.
