4.3.2 Saving the Machine Data
X Open the SITEST submenu
Machine data
and select the button
Save WPC machine data…
.The
dialog box
Save WPC machine data
will open.
X Specify the target folder in the dialog box.The file name will assigned automatically.
X Select the button
OK
. The WPC machine data will be saved.
We recommend that you save the machine data after each calibration run.
4.3.3 Restoring Machine Data
If a new controller board has been installed in the WPC4 control unit, the machine data saved can be
restored to the controller board. This function checks whether the serial number in the file matches the
current serial number on the WPC controller board. If the WPC4 does not have a current serial number
(in this case, the serial number will be 000000000), this will be evaluated as an invalid serial number and
the transfer will be canceled. You then need to create a valid serial number in the WPC4 (see
Initialization) before you can restore the machine data. If you are unsure, check the serial number
against that stamped on the type plate.
X Open the SITEST submenu
Machine data
and select the button
Restore WPC machine
data….
The dialog box
Restore WPC machine data
will open.
X In the dialog box, specify the source folder in which the machine data file is saved.
X Select the button
OK
. The WPC machine data will now be transferred to the WPC.
If the serial number in the file does not match the current serial number on the WPC controller board, the
following message will appear:
NOTE: Path
The path can be selected as required. However, it is advisable to save the WPC4 machine data
in the same folder as the placement machine data.
X Save the WPC4 machine data at:

4.3.4 Standard Values
If you are unable to calibrate the WPC4 anymore, due to incorrect axis parameters, the saved machine
data can be copied from the station computer to the WPC (restoration of machine data). If there is no
backup file available, create a standard machine file as the defined basic state. From this basic state,
the WPC4 can and must be recalibrated.
Saving machine data with invalid values
X Start SITEST.
X Open the menu:
SITEST Machine data
X Click on the selection button:
Save WPC machine data …
.
X Select the data folder.
X Click on OK.
Editing machine data
X Close SITEST
X Switch over to the operating system level.
X Open the machine file with a text editor (e.g. Notepad)
Windows: Start - Programs - Accessories - Notepad
Note: The special characters {,}, <,>,[,],\, must be left where they are in the file. They help the machine
controller to assign the individual data. If the format of the WPC.ma file is no longer correct, restoration
(download) will not succeed. In this case, the old data will remain on the controller board. The text lines
"reserved" indicate parameters which are currently not needed.
X Enter the standard values, from the table below, in the machine file.
X Save the file and close the editor (Notepad).
Restoring machine data with standard values
X Start SITEST.
X Open the menu:
SITEST Machine data.
X Click on the selection button:
Restore WPC machine data …
.
X Select the data folder.
X Click on OK.
Calibrating the WPC4
The WPC4 only has one valid data set. This now needs to be adapted to the current WPC4.
X Perform all necessary calibration steps.
Standard values for axis positions:
Parameter Lifting axis Feed axis
Zero point correction 0 0
Transfer position - - 770000
Refill position - 13000 -
Min position approached - 14000 - 2000
Max position approached 48000 780000
