The Delem DA-56 can be programmed by authorized users who have access to create or edit programs and tool data. The controller has a keyswitch to prevent unauthorized programming. When the keyswitch is in the off position, the operator can only execute a selected program without changing parameters. Programming is simplified through 2D graphical tools, and the system automatically determines bend sequences.

    Delem 8.2. Manual operation of the axes It is possible to move an axis by turning the handwheel on the front panel of the control. After pressing the function key ‘manual pos’ in the main screen of manual mode, the following screen appears: Put the cursor bar on the axis you wish to move with the handwheel.

    The Y-axis must be below mute-point. A pressing command must be given to the CNC. • To teach You can teach an axis a correct position within the manual positioning mode. When you have moved an axis to a certain position with the handwheel, you may want to store this position. To do so, press the ENTER key within this screen.

    Delem Automatic / step by step mode 9.1. Introduction The automatic mode executes the program (programming mode) automatically bend by bend after pushing the ‘start’-key.When a new bending program is selected you must check your tools and tool positions in your machine. This is also indicated with a ‘check tools’ warning message when you enter the automatic mode.

This function can be activated when the cursor is on the parameter for angle correction (‘corr. α1/α2’). It is only available if a product is loaded that contains a radius bend. When the function is activated, a new window appears in which the correction can be entered.

    9.2. Step mode In the step-by-step mode you have the same possibilities as in the automatic mode. There is only one difference. After each bend cycle, the control will stop. To continue working, you must start the control again by pressing ‘start’ on the front panel of the control. After each bending step, the control can stay in the current bend or jump to the next bend.
