DA-41 press brake control Operation Manual

The DA-41 is a programmable control for conventional press brake machines. This manual assumes that the DA-41 is configured using the bending depth formula. If the unit is configured for bending depth calculation based on tables please refer to the version 2 user manual (8064-901C). If you are not sure which method is configured please contact your machine supplier.


Front panel

The following picture shows a representation of the front panel. The panel contains one display and several keys for programming and axis control. The display will be explained in the next section.

This screen displays an overview of the available tools. The table indicates the tool number, the V-opening, the tool angle and radius. During product programming, the programmed tool properties are used for the calculation of Y-axis values. To enter the tool properties place the cursor on the applicable field of a tool and simply enter the desired value.

Program constantsing
