Page 18
2.3 SET-UP 2.3.1 GENERAL CONSIDERATIONS Verify that a proper location for the feedback devices has been selected without blocking the access to the various machine controls. Verify that the alignment and adjustment of the different parts of the encoders and/or linear scales are within the tolerances indicated in their installation instructions.
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. GENERAL PARAMETERS O.K.
Page 21
This display mode shows the following fields or windows: The position coordinates corresponding to each selected axis. They are given in absolute or incremental values and in radius (RAD) or diameter (DIA) depending on the setting of machine parameter Px09. 5 windows in reverse video showing the display conditions selected for the axes positions.
Page 22
PRESET This function can be used to preset (assign) a position value to the selected axis both in absolute or incremental modes. CHANGE REFERENCE This function is used to select a new reference. Once this key is pressed, the DRO will “wait”...
Page 23

Use one of the following options to select one of the shown functions: Press the key corresponding to the number associated to the desired function. Use the to move the cursor and when the desired option is highlighted (reverse video), press...
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:...
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 29
When presetting a Part Zero, the Floating zero corresponding to that reference is also modified in such a way the distance between both zeros is kept the same. FLOATING ZERO PART ZERO FLOATING ZERO PART ZERO HOME Chapter: 2 Section: Page COORDINATE PRESET MACHINE AND POWER CONNECTION...
TOOL COMPENSATION This DRO has a tool compensation table for up to 99 tools showing the length and radius of each tool. It is also possible to apply or not tool compensation to each axis indicating the tool length and radius used in the compensation; but no tool compensation cannot be applied to rotary axes.
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.
2.10 TROUBLESHOOTING Before contacting the service dept. of FAGOR AUTOMATION, it is recommended to do some troubleshooting in order to ease the finding of the defective component. This troubleshooting operation will be carried out when: Any of the axes does not count or it does it erroneously.
MACHINE PARAMETERS INTRODUCTION The VNP400 can be easily matched to the machine by setting its machine parameters. They indicate the type of feedback being used, the counting direction, the display resolution, leadscrew errors to be compensated, etc. These values may be introduced by hand from the keyboard or from a peripheral device via the optional RS 232C serial port.
Page 34
OPERATION WITH MACHINE PARAMETERS To access this operating mode, select the “INSTALLATION PARAMETERS” option after pressing It is possible to operate with general parameters, parameters specific for each axis or initialize (reset) them all. Once the type of operation is selected, the DRO will display the parameter table corresponding to that field indicating in each one of them their available options.

EXIT Quits the editing mode without updating the internal parameter table with the new values. It keeps the “old” ones. The DRO will display again the available options to operate with the machine parameters. When pressing the key, the DRO exits the parameter editing mode keeping the previous table values.
SETTING MACHINE PARAMETERS 3.3.1 GENERAL PARAMETERS P000 It selects the language used by the DRO. Note that the texts corresponding to the softkeys will always be in English. P001 Indicates the type of machine being used: Mill or Lathe. The DRO will show the specific functions corresponding to the type of machine being selected by this parameter.
Page 37
P006 Indicates the number of data bits per character transmitted via RS 232C. Uses the 7 least significant bits of an 8-bit character. Used when transmitting standard ASCII characters. Uses all 8 bits of the character. Used when transmitting special characters (codes greater than 127).
Page 38
P011 Indicates the command and data source for the DRO. LOCAL The data entry is done from the DRO keyboard. REMOTE The data entry is done via the RS 232C serial port. In this case, the complete keyboard except the key is inhibited.
Page 39
3.3.2 PARAMETERS FOR THE AXES The VNP400 has 4 groups of machine parameters to associate the DRO with each axis. The meaning of all groups is the same and its numbering consists of three digits where the first one indicates the axis number and the other two the parameter number.
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.
Page 42
Example 2: To obtain a 0.1µm resolution on a linear axis with sinusoidal feedback signal. 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.
