4 Machine Parameters - ESSECI

1 September 2004 What is a Machine Parameter?4 34 Machine What is a Machine Parameter?A contouring control must have access to specific data ( , traverse distances, acceleration) before it can execute its programmed instructions. You define these data in Machine list of Machine Parameters is divided into groups according to topic. If there is more than one input value for a single function ( , a separate input for each axis), the parameter number is extended by indices. Index zero is always axis 1, index one is axis 2, :Enter into , using the code word AXISNUMBER =, the number of axes being used, so that only the necessary index Parameters are parametersTopics10 to 999 Encoders and machines1000 to 1399 Positioning1400 to 1699 Operation with Velocity Feedforward Control1700 to 1999 Operation with Following Error (Servo Lag)

In this case, the Parameters serve as on/off switches for these functions.

4 2004 Input and Output of Machine Parameters4 Input and Output of Machine ParametersIf the Machine Parameters have not yet been entered in a HEIDENHAIN contouring control ( , before commissioning), the iTNC presents the list of Machine Parameters after the memory test:8 Enter the values for the Machine Parameters either by hand on the keyboard or download them through the data Input FormatYou can enter the input values either in decimal, binary (%) or hexadecimal ($) a number for each Machine value represents, for example, the acceleration in mm/s2 or the analog voltage in V. You can add a comment to your entry by preceding it with a semicolon (;).

5 Binary input (%) is the best format for Machine Parameters that activate individual functions : Disabling soft keys for file types with soft keys for datum tables and text files are to be disabled:0: Do not disable 1: DisableBit 0 HEIDENHAIN 1 ISO 2 Tool 3 Datum 4 Pallet 5 Text 6 HELP 7 Point value for =Binary%00101000 Hexadecimal$28 Decimal40 (32+8)4 6 HEIDENHAIN Technical manual for iTNC 530 Special case: Entering a formulaOnly for (linear distance of one motor revolution) and for (type of dimension for transformation).You can enter a formula instead of a fixed value. When entering the formula, you must pay attention to the case of the letters (whether they are small or capital).

7 The following errors are displayed:If the control does not recognize any errors, it automatically exits the Machine parameter editor and is ready for you do not make any entries in the Machine parameter list during initial commissioning and exit the editor with the END key, the iTNC generates a standard Machine parameter list (MP NAME). In this list the iTNC is defined as a programming station with the HEIDENHAIN standard colors. In all other Machine Parameters a default value is can enter more than one Machine parameter list in the iTNC:8 Select the lists with the PGM MGT key and the SELECT soft key. The last selected Machine parameter list becomes active when you exit the Machine parameter errorMeaning0No MP number found1 Invalid MP number2No separator (:) found3 Input value incorrect4MP doubly defined6MP cannot be stored4 8 HEIDENHAIN Technical manual for iTNC Changing the Input ValuesA Machine parameter list can be changed either with the Machine parameter editor or directly through the PLC.

8 The List of Machine Parameters includes the following symbols: manual input8 Call the Machine parameter editor through the MOD function code number : By entering the code number 95148, you gain access to the complete list of Machine Parameters . By entering the code number 123, you gain access to a subset of Machine Parameters . This subset can be changed by the user (see User s manual ). Machine Parameters that can be accessed through the code number 123 are indicated in the list with the symbol exit the Machine parameter editor, press the END parametersYou can access some Machine Parameters without first entering a code , define up to 16 Machine Parameters and define the associated dialog in The dialog is shown whenever the USER Parameters soft key is pressed (up to 37 characters).

9 8 Select the MOD function USER the Machine parameter listTo protect the current Machine parameter list from being edited through the code number 95148:8In the file, define a new code number in the entry MPPASSWORD = for editing the Machine parameter list. Then it is no longer possible to edit through the code number protect individual Machine Parameters against editing:8In the MPLOCKFILE = entry in the file, enter the path of a Machine -parameter subfile. Then it is only possible to edit those Machine Parameters that have no value assigned in this file. If there is a difference between the current MP value and the MP value in this subfile, the control displays an error message and a window offering the value from the subfile for your by / ReactionCN123 The MP is also accessible through the code number MP can be changed via the PLC; it can also be changed in a running NC program during a strobe MP can also be changed while an NC program is the MP results in a axis must be moved over the reference mark 2004 Input and Output of Machine Parameters4 9 Overwrite Machine parametersMachine Parameters can be overwritten by the PLC or from an NC macro.

10 In the Program run, full sequence, Program run, single block and Positioning with manual data input operating modes, Machine Parameters can be overwritten only when the drives are stationary, and not during a the input values via PLCYou can also change the Machine Parameters through the PLC. The following modules are available for this purpose Module 9031 Overwrite Machine parameter Module 9032 Read Machine parameter Module 9310 Read the Machine parameter from the run-time memory Module 9033 Select Machine parameter file Module 9034 Load Machine parameter subfileThe Machine Parameters that you can change with Module 9031 or Module 9034 are indicated with PLC in the the manual and Electronic Handwheel operating modes Machine Parameters should not be overwritten during a movement.
