    SPECIAL FUNCTIONS 6.7.1 FEEDBACK INHIBIT (G47, G48) In some applications, after positioning the part, sheetmetal, etc. it is necessary to correct its position. This correction is made by an external device not controlled by the CNC. When executing function G47, the CNC ignores the possible movements caused by that device, thus inhibiting the feedback pulses.

    6.7.2 G47, G48 AS OPENING OF THE AXIS LOOP In particular applications such as presses, metal forming machines, sheetmetal forming machines, etc., the part undergoes a movement or pull while it is machined. By means of functions G47, G48 the CNC allows the loop of the axis undergoing the pull to be opened or closed.

    6.8.4 LOADING THE PUNCH SIZES (G60) Function G60 can be used in two different ways. For loading zero offsets This is explained in section 6.3.3.2 of this same manual. For loading the punch dimensions This is particularly meant for punching machines. Machine parameter "P101(7)=1" must be set.

  • Page 86: Parametric Programming

    PARAMETRIC PROGRAMMING A parameter takes the place of a numeric value in the various functions of the program. The programmer may use these parameters when editing his/her own programs. Later on, and during execution, the CNC will replace these parameters with the values allocated to them at the time.

  • Page 89 F11 Comparison It compares an arithmetic parameter with another one or with a numeric constant indicating whether the first operand is equal, different, greater, or smaller than the second operand. This operation is greatly used when working with conditional jumps G26, G27, G28 and G29, which are described later on.

  • Page 90: Access To The Arithmetic Parameter Table

    6.9.3 ACCESS TO THE ARITHMETIC PARAMETER TABLE The CNC stores the values of the arithmetic parameters in a table. These values may be modified when executing parametric blocks or by accessing this table in the editing mode. Press to access the Editing mode and then press [F1] [P]. The information displayed by the CNC will look like this: The upper display shows the parameter number currently selected.

  • Page 92: Unconditional Jump Function (G25)

    6.9.4 UNCONDITIONAL JUMP FUNCTION (G25) Function G25 may be used in two ways: To jump to the desired block within the same program and continue executing from that block on. To execute a particular section (between any two blocks) of the program several times.
  • Page 93 Then, press [.] and key in the number of times this section is to be executed. For example: N030 G25 N5.20.81 If the number of repetitions is not indicated, the CNC assumes a value of "1" meaning that it will only execute it once. For example: N030 G25 N5.20 is the same as N030 G25 N5.20.1 When using a parameter to indicate the program section to be executed, all three fields of the G25 statement will be parametric.

    6.9.5 CONDITIONAL JUMP FUNCTIONS (G26, G27, G28, G29) They are similar to function G25 (unconditional jump). Functions G26, G27, G28 and G29, before jumping to the indicated block or executing the indicated program section, check whether the required condition is met or not. G26 Jump if zero.
