This page sets the entry speed of the blade into the material to be cut during the automatic cycle.
Blade [cm] | Instantaneous position of the Blade axis expressed in centimetres. |
Drop speed [cm/h] | Instantaneous speed of the Blade axis expressed in centimetres/hour. |
![]() | Press for 7 seconds to reset the position of the blade axis. |
CARRIAGE | 1 : Preset quota, heights and speeds are referred to CARRIAGE 1 2 : Preset quota, heights and speeds are referred to CARRIAGE 2 |
Preset quota [cm] | Height value of the blade axis which is used to calculate the heights of the various entry speeds which are set in the bottom side. Arrival value of the blade axis lifting at the end of each cut. It is important to be sure that this value is actually higher than the maximum height of the block, to avoid that the carriage starts moving when the blade is still inside the block |
![]() | Press to learn the pre-set value of the blade axis. Before any automatic cycle it is recommended to set the blade to a safety value above the block and learn the relevant pre-set value through this key |
You can set 3 different heights (ENTRY 1, ENTRY 2 and ENTRY 3) during the entry of the blade into the block and associate a different drop speed to each of them.
AUTOMATIC WORK : at the end of the space used for the entry of the blade into the block, the remainder of the lowering uses the speed that was set in this parameter.
EXIT : Space of cutting end.
Example: You want to set a pre-set value of 100 and three Heights of 10 (with speed A), 20 (with speed B) and 30 (with speed C). Besides the automatic work is set at speed D and an exit 5 with speed E.
When the automatic cycle starts the machine will perform the first 10 cm at speed A, the second 20 cm at speed B and the next 30 cm at speed C. The other 35 cm (100 – Entry 1 – Entry 2 – Entry 3 – EXIT) will be performed at speed D.
The last 5 will be performed at speed E. At the end of the downward movement the blade moves up again with maximum speed.
NB. You can enter a Height equal to 0 but you cannot associate a null Speed to a Height.

In this page you can reset the value of the two Carriages and use the semi-automatic positioning function.
Blade thickness [cm] | Thickness of the cutting blade expressed in centimetres. |
![]() | Press to enable/disable the correction of the positioning value of the Carriage with the thickness of the cutting blade. An associated led indicates if the correction is present (ON) or is not (OFF). |
Carriage 1/2 [cm] | Instantaneous position of the axis of the Carriage 1/2 expressed in centimetres. |
Cut thickness [cm] | Movement value of the axis of the Carriage. This positioning is more accurate than the jog functions of the axis. The entered value is meant as the INCREMENTAL movement of the axis.. |
START | Press the START button to start the positioning of the carriage at the set value. |
STOP | Press the STOP button anytime if you want to stop the positioning of the Carriage axis. |

Procedure to perform a cut in “MANUAL SINGLE CUT” mode
1 | Make sure that the device is not in the alarm state, and that it is in the MANUAL state, signalled by icon: ![]() |
2 | Manually move the axes Blade and Carriage 1/2 in the starting point of the cut to be performed. |
3 | Press and hold the tensioning button located at the middle of the MAIN MENU page |
4 | The tensioning procedure ends when the machine reaches the medium pressure. This situation is signalled in the MAIN MENU page with the string located in the middle of the page: TENSIONED BLADE |
5 | To start the flywheel motor press the white START button located at the panel front under the terminal. |
6 | To start the single cut press the F2 key. ![]() |
In the Single Cut procedure the blade starts from the value in which it is and goes down to 0 (bench level) or to the lower blade limit switch with a speed regulated by the potentiometer located at the front of the operator panel.
Once the 0 value, or the lower blade limit switch, has been reached, the main motor stops and the blade remains at the reached value.
Premise: To correctly perform the automatic works, it is required to follow a precise order of operations, as shown in the following list:
1 | Make sure that the device is not in the alarm state. |
2 | Take the block loaded on the Carriage 1 to the required position. |
3 | Lower the blade to the starting measure. |
4 | Press and hold the tensioning button located at the middle of the MAIN MENU page |
5 | The tensioning procedure ends when the machine reaches the medium pressure. This situation is signalled in the MAIN MENU page with the string located in the middle of the page: TENSIONED BLADE |
6 | To start the flywheel motor press the white START button located at the panel front under the terminal |
7 | Press the F1 button ![]() It is also signalled by icon ![]() |
8 | Wait until the flywheel strokes have reached the measure indicated in the set-up. |
9 | To start the automatic cycle press the F2 key. ![]() |
To stop the automatic work anytime, press the STOP button located on the panel front under the terminal or the F2 key.
When the automatic cycle is started again, the program asks if it must re-start from the beginning, by resetting what was done until then, or continue the previous cycle.
Automatic cycle has this steps:
1 | Operator must move in MANUAL the Carriage 1 and the blade where the first cut begins. After he has to regulate the metal device to intercept the Carriage 2 limit-switch, corresponding to the first cut of the second block. |
2 | Start the blade, select automatic state by pressing F1 key and start cycle with F2 key. |
3 | Machine executes all the programmed cuts for block on Carriage 1, or stops when it reaches the forward limit-switch. |
4 | Blade moves to the upper quota of the two self-learned blocks and Carriage 1 moves to the backward limit-switch. |
5 | When Carriage 1 is in a safe area, Carriage 2 axis moves to reach the first cut position. |
6 | Machine executes all the programmed cuts for block on Carriage 2, or stops when it reaches the forward limit-switch. |
7 | At the end of the cuts, Blade moves to the upper position, main motor and water stops and Carriage 2 moves to the backward limit-switch. |
