Drop setup

: return to the MAIN MENU page.

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.
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.

USCITA : 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.

Carriage Movement

: return to the MAIN MENU page

In this page you can reset the value of the Carriage and use the semi-automatic positioning function.

Carriage [cm] Instantaneous position of the axis of the Carriage expressed in centimetres.
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).
Target value [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.

Program setting

: return to the MAIN MENU page

In this page you can program the automatic cycle.

The program ensures to enter at most 10 steps each with a thickness of the slab to be obtained and the number of slabs to be cut.

THICKNESS Dimension in centimetres of the required blade thickness.
SLABS QUANTITY Number of slabs to be cut at each step of the program.
Carriage direction Movement direction of the carriage axis at the end of each cut:
: the Carriage moves clockwise
: the Carriage moves counter-clockwise
Trimming Enabling / Disabling of the trimming cut:
: trimming cut disabled
: trimming cut enabled
Blade thickness [cm] Thickness of the cutting blade expressed in centimetres
Block length [cm] Length of the block to be cut expressed in centimetres. This information is used to control the accuracy of the automatic program. If the total thickness of all the programmed cuts exceeds the dimension of the block, the system gives a warning signal displayed in the Main Menu.

Diagnostics menu

Through this screen you can access the various available diagnostics sections:

1 - Digital inputs and outputs diagnostics

2 - Counting and analog output diagnostics

There is also some information about:

Fw name : firmware present in the device and related checksum;

Task time : average time of the CPU cycle with indications about the scanning Maximum Time and Minimum Time;

CPU time : total time since the CPU has been in the RUN state (hh:mm)

: return to the MAIN MENU page

Inputs and outputs diagnostics

By pressing the “INPUTS / OUTPUTS” key you can display the following screen, which shows the states of each digital input and outputs and of the two analog inputs.

For each analog input it displays the value in bit and the resulting value after the scaling.

Counting and analog diagnostics

By pressing the “COUNT. / ANALOG” key you can display the following screen, which shows the counting of the encoder of the axis drop and the value of the analog output used.

The counting is displayed in encoder pulses and, in smaller dimensions, the counting value in measurement unit.

: scrolls forward the pages of the alarm log file;

: return to the ALARMS page

: passage to the removal page of the alarm log file. This page is password-protected. The code to enter it is 485000.

Maintenance

The machine is provided with a very important alert regarding ordinary maintenance.

Indeed it requires, every 200 working hours of the fly-wheel motor, a general control described in the mechanical characteristics manual provided with this manual.

After 200 working hours, the following alert will be displayed at any start-up of the fly-wheel motor:

Press the key to confirm the display.

To reset its display you need to enter a maintenance performed code.

Contact the mechanical service by BM S.r.l. to perform the operation. For this alert you do not need to perform the maintenance to keep on working. However it is recommended to perform the intervention for it as soon as possible.

3. Operation

Manual

In the manual state the only allowed movements are the jog ones of the two axes.

The manual state is indicated by icon: and by the led of the F1 key which must be off.

To move the axes in jog, make sure that the device is not in the alarm state.

NB. the Carriage cannot be moved if the flywheel motor is running.

F3 JOG FORWARD AXIS CARRIAGE. Press to manually move forward the Carriage.
F4 JOG BACKWARD AXIS CARRIAGE. Press to manually move backward the Carriage.
F5 JOG UP BLADE AXIS. Press to manually move upward the blade.
F6 JOG DOWN BLADE AXIS. Press to manually move downward the blade.

Single cut

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: and by the led of the F1 key which must be off.
2 Manually move the axes Blade and Carriage 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

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.

Automatic Cut

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 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 to set the machine to the AUTOMATIC state. The related led starts flashing to signal the automatic state with the stationary cycle.
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.

After the natural end of the automatic cycle the blade goes to the uppermost position and the program is automatically reset.
