Create .dat-file
Tapping Create .dat-file will store the most important productand control data, by default on the connected USB stick. Thisinformation can be helpful for the maintenance support.
Calibration point
Set the Y-axis calibration point. Refer to paragraph 6.7.1 fordetails.
Restart controller
This will reboot the DA-40T system.
6.7.1 Setting the calibration point
To calibrate the bending depth calculation the calibration pointmust be programmed. This parameter defines the Y-axisposition when the tools are closed. In other words, the Y-axisposition that corresponds with the situation where the lowestpoint of the punch is at the same level as the upper side of theV-die (pinching point with sheet thickness = 0).
This procedure has to be repeated each time the height of the tools that are mounted in the machine have changed.
To set the calibration point, tap on the ‘calibration point’ soft keyon the Maintenance tab in Settings mode.
A practical way to calibrate the machine is to place a sheet ofmaterial with known thickness between the tools and find the Y-axis position at which the punch just touches the sheet (pinchingpoint) using the manual positioning function.
The first parameter indicates the Y-axis position. The second parameter is to define the thickness of the sheet that has been used for the calibration. When the thickness value is entered, the calibration point is calculated automatically.
6.8 System information
On this tab system information can be found. It shows the actualsoftware version; software update functionality is available hereas well.
Update software
With ‘update software’ the control can install a software update set from a USB stick. The directory browser will help to selectthe desired update and initiate the installation process.
