  • Page 19: Reference Systems

    REFERENCE SYSTEMS The machine where the VNP400 DRO will be used must have the following reference and datum points defined for each axis: Machine Zero Point or home. It is established by the manufacturer or operator as the origin of the machine’s coordinate system.
  • Page 20 On power-up (done using the ON/OFF switch on the rear panel), the DRO performs an initial self-test and, depending on the result, the DRO will act the following way: If the self-test is successful, the DRO will display the following screen: FAGOR VNP400 VERSION: RAM TEST O.K.

  • Page 25: Home Search

    The DRO uses the marker pulses (Io signal) provided by the feedback devices such as linear transducers (scales) and rotary encoders. Since linear transducers have several marker pulses (FAGOR scales have one every 50mm) and encoders have one per revolution, it is necessary to always “find” the same marker pulse at the same physical home position.
  • Page 26 Once home is found, the DRO will recover the absolute and incremental zeros corresponding to each reference (REF 0 thru REF 9) when recalled. Note: It is recommended to perform a home search after power-up, especially when working with leadscrew error compensation. Page Chapter: 2 Section:...

  • Page 27: Zero Offsets

    ZERO OFFSETS The VNP400 allows the setting of up to 9 absolute (Part Zero) and 10 incremental (floating) zero offsets in order to use the coordinates relative to the part drawing without having to modify the particular coordinates of the various points of the part.
  • Page 28 COORDINATE PRESET These presets are used when working from position value (coordinate) towards zero instead of working from one position value to the next. To preset a coordinate, follow these steps: The DRO must not display any menu windows superimposed on the screen. If this is not the case, press Position the machine at the point to be preset.

  • Page 31 When a positive sign is selected, the position value shown by the DRO will be the real axis position plus the value indicated in the field corresponding to the selected tool. When a negative sign is selected, the position value shown by the DRO will be the real axis position minus the value indicated in the field corresponding to the selected tool.

  • Page 40 Px02 Px03 These parameters are used when Px01 has been set to display the result of an operation between the readings of two axes. Px02 indicates the first operand and P03 the second one. All linear axes can be used as operands even the same axis; but no rotary axes can be used as operands.
  • Page 41 Px09 Indicates whether the axis position can be displayed in Radius and Diameters. By default, the DRO shows the position value in radius which is the same as the one given by the feedback device. The diameter display will show (if set to be allowed) a position value twice that of the radius.

The multiplying factor that the DRO applies to sinusoidal feedback signals can be x5, x10, x20 or x25 besides x2 and x4. Therefore the obtainable values are: x100 Using a linear scale with a grading pitch of 20 µm, the maximum possible resolution is 20µm/100 = 0.2µm and 0.1µm with a grading pitch of 10µm...

  • Page 44 Px14 Indicates the scaling factor to be applied to the programmed position values during the execution of a program. The DRO will multiply the programmed position by the value assigned to this parameter when executing a program. This way, it is possible to make parts of different sizes from the same original part program by simply changing the value of this parameter as necessary.
  • Page 45 (referenced) every time it is powered-up. This home search must always be done at the same marker pulse since the feedback device might have more than one marker pulse. Fagor scales have one every 50mm (about 2 inches) and the encoders one every revolution.
