USER INSTRUCTIONS FOR CNC MECCANICA SCOTTI
DESCRIPTION :
- Dimension 335 x 315 x 235
- Weight about 19 Kg
- Operative temperature from 2° to 35° C
- Moisture from 20 % to 80 %
- Keyboard 20 keys
- LCD display 16 x 2 backlighted
- Power supply 220 V AC +/- 10 %
The Control allows 2 types of released functioning allowing, its use as indipendent system
(MANUAL WORKING) or as interfaced to the Machine tool (WORKING from PROGRAM).
MANUAL WORKING .
In manual made, all the function set by keyboard, are immediately performed everytime you push a
key of execution ( Î ) .
In general (apart some cases) the command sintax is the following :
( X ) ( X ) ( X ) ( X ) ( X ) NUMERICAL VALUE (It appear on the second line on the display)
[ ( 2ND ) ] ( X ) FUNCTION CODE (It appear on the first line on the display)
( Î ) EXECUTION KEY
To minimize keynumber, every key has a second function; if you push it after the key " 2ND ", it
performs the second function.
Example : - The key 5 pushed alone means 5.
- The key 5 push after the key " 2ND " means " DELAY ".

( Î ) = EXECUTION
***** N. B. *****
The control will hold the current position, while the Table is turning, untill you turn off the power, in
this case you must reset the Table.
You can also loose teoric Zero position if you stop the machine by stop key (-) an indexed rotation
(degrees) (indexing) (return to zero) forward and backwards.

MANUAL MODE
The manual mode is active when appear on the display Mecc. SCOTTI or MANUAL MODE
EXAMPLE
• If you want to carry out a rotation of 90 degrees and 12 centesim of degree with the tilting axis :
Type ( 9 ) ( 0 ) ( 1 ) ( 2 ) = NUMERICAL VALUE
(BAS) = FUNCTION (TILTING DEGREE IN ABSOLUTE)
(Î) = EXECUTION
• If you want to SET THE ZERO PIECE RESETT TABLE
N.B. The zero piece can not be the mechanical zero and it can be carry out everywhere with the
function ( 1 ) ( 2nd) ( 8 )
Type ( 4 ) (OUT ) (Î) = MANUAL TILTING AXIS
( 2 ) = NUMERICAL VALUE
( 2nd) ( 8 ) = SET ZERO FUNCTION
(Î) = EXECUTION
***N.B.***
The control unit memorized the position until you take out the supply while the table is moving ; in
this case it is better to reset the mechanical zero.
You can lose the theorical position of the table also when you stop an indexing rotation
(DEGREE,INDEXING,RETURN TO ZERO) forward and backwards typing STOP (ALT).
• If you want to come back to the ZERO PIECE or to reach an absolute angle :
Type ( 0 ) = NUMERICAL VALUE
(BAS) = FUNCTION (RETURN TO ZERO)
(Î) = EXECUTION
• If you want to research the MECHANICAL ZERO TABLE
Type ( 4 ) (OUT) (Î) = MANUAL TILTING AXIS
( 1 ) = NUMERICAL VALUE
(2nd) ( 8 ) = FUNCTION OF ZERO RESEARCH
(Î) = EXECUTION
7
KEY and FUNCTION USEFUL IN MANUAL
STP
The “QUOTA VISUALISATION” key is very useful in manual way.
In manual way, after ever positioning it is possible to control the quota, that the table has reached,
pushing the STP key.
The same key STP pushed in EDIT, makes the program run increasing (for example from step N01 to
step N02), while pushing the “2nd STP” keys in EDIT, it makes the program run decreasing (for
example from step N02 to step N01”
2nd 2nd
When you push two time consequently the 2nd allow you to cancel a numerical value, a function or
what the display show.
ATTENTION ! the 2nd key do not permit a break in the program or a positioning.
The 2nd key is used in MANUAL and in EDIT with the same meaning.
ALT
The ALT key has only the function to stop a positioning or a function.
The ALT key is used in MANUAL, EDIT and in AUTOMATIC.
8
MAIN OPERATION TO RESTORE OR TO CREATE THE “ZERO PIECE”
• In order to restore or create “ZERO PIECE” in the circumference we suggest operate in this way :
Type the funciton :
( 4 ) (OUT) (Î) = MANUAL TILTING AXIS
( 4 ) (2nd) ( OUT ) (Î) = AUTOMATIC TILTING AXIS
Carry out “TILTING ZERO”
( 4 ) (OUT) (Î) = MANUAL TILTING AXIS
( 4 ) (2nd) ( OUT ) (Î) = MECHANICAL ZERO TILTING AXIS
Reset the tilting axis
( 1 ) ( 2nd) ( 8 ) = ZERO PIECE TILTING AXIS
ATTENTION ! you can lost ZERO PIECE when :
• Carry out the MECHANICAL ZERO TABLE
( 1 ) ( 2nd ) ( 8 ) ( Â )
• Break off the supply of 220V while the table is rotating.
• For particular reasons to check carefully when they happened.

ERROR MESSAGE
The control gives some messages about main malfunction that could happen. These messages appear
in full extention and they are :
1. " CHECKSUM ERROR " : Checksum error of memory if the buffered memory has lost some
file because of a BLACK-OUT or a storm, it is necessary to check the saved programs.
This error signal will inform the utilizer that the buffered RAM BATTERY is exhausted
(Duration about 4 years) .
Check the EPROM and control that the bridge on the two pins is near the battery.
2. " BLACK OUT " : Positioning error. The error is caused by an electrical black out during the
motor rotation. In this case the motor loses its Zero reference.
It is necessary to remake the Zero positioning.
3. " LOCKING ERROR " : Table locking error.
If after a long period from the locking command, the piston has not reached the correct
position, it will appear " LOCKING ERROR " .
Check air pressure and the locking solenoid valve supply.
Check the good functioning of the locking/unlocking proximity.
Control that the table parameters are enable for the locking function.
4. " UNLOCKING ERROR " : Table locking error.
If after a long period from the locking command, the piston has not reached the correct
position, it will appear " UNLOCKING ERROR " .
Check air pressure and the locking solenoid valve supply.
Check the good functioning of the locking/unlocking proximity.
Control that the table parameters are enable for the unlocking function.
5. TABLE POSITIONING ERROR ON THE 360 DEGREE.
Check the load on the table that must correspond with the one indicated on the Load Table
Schema.
Check the militar connector it should be dry and all the wires are well welded.
Check the mechanical parts of the table that functioning well.
Check the oil in the worm screw and helical ring gear box.
Lubricate the table plateau through the 2 oiler
The driving card can be broken, control the switch on/off of the green LED, when the table
move.
6. ENCODER ERROR
The encoder show that the table is not in the programmed point.
See alarm point 5.
Check the good functioning of the encoder.
Check the encoder cable, probably there are some tug wires.
Connector pin.
7. THE TABLE GO ON ROTATING AFTER HAVING SET A MACRO INDEXING OF
THE CIRCUMFERENCE :
Check if you have insert the function of “ARC TO INDEX” ( 360 00 ) (2nd ) ( 2 ) ( Â ) from
manual way.
10
8. THE CNC UNIT DO NOT GIVE BACK THE SIGNAL TABLE IN POSITION TO THE
TABLE
Check the table parameter : 3° value must be from 2 to 9.
Check the fuse in the fuseholder inside the electric box situated in the low-front part of cnc
unit.
Check the fuse in the fuseholder inside the electric box situated in the high-front part of cnc
unit.
11
PROGRAMMED FUNCTIONING
The same functions that you can carry out in manual, may be carryed out also by program.
You can save 8 programs of 49 steps each.
The steps you can write in the program are 49, but if the program has more then 49 steps, the CNC unit
memorized the other steps in the next program and cancel everything in that program.
Program saving is extremely simple. Let's try with a first simple program that carries out a series
positionings, sequentally and autonomally.
1. We can choose a program number,for example the No. 3.We want that the CNC stepping carries
out 3 sequential moviments : 1 degree forward, 15 degrees forward and 90 degrees forward.
TYPE :
( 3 ) ( 2ND ) ( 1 ) ( Î ) = RECALL the PROGRAM N°.3
( 4 ) ( 5 ) ( 6 ) ( PGM ) = SAVING MODE (ACCESS EDIT CODE)
N1 ( 1 ) ( 0 ) ( 0 ) (BAS) = 1 DEGREE FORWARD
( Î ) = SAVE STEP N°.1
N2 ( 1 ) ( 5 ) ( 0 ) ( 0 ) (2ND ) ( BAS ) = 15 DEGREES FORWARDS
(Î) = SAVE STEP N°.2
N3 ( 1 ) ( 2 ) ( 0 ) ( 0 ) ( 0 ) ( BAS ) = 90 DEGREES FORWARD
(Î) = SAVE STEP N°.3
N4 ( FPG ) = STOP PROGRAM
(Î) = SAVING
( ALT ) (2ND ) (2ND ) = To EXIT from the SAVING MODE ( EDIT )
Now the program is SAVED.
To execute this program, you must recall it with its number and start "AUTOMATIC " mode.
( 3 ) (2ND ) ( 1 ) ( Î ) = RECALL PROGRAM N°.3
(2ND ) ( PGM ) = AUTOMATIC MODE
At this point the control will carry out sequentally the 3 programming movements and when it stops
as it reach " STOP PROGRAM " step.
To exit from " AUTOMATIC PROGRAM EXECUTION " type :
( FPG ) ( ALT ) (2ND ) (2ND )
12
A similar program, however, has not a great interest if you don't give the possibility of an exterior
entity (Es. Machine tool) to call these movement.
The function that allow an exterior entity to interact with the control is the " Wait for outside start "
function : ( 2ND ) ( 0 ) .
Let's see, now, a program that wait for a signal from outside to carry out a rotation of 90 degrees.
2. We choose a program where we can save what we want to carry out, example program No.7.
TYPE :
( 7 ) ( 2ND ) ( 1 ) ( Î ) = CHOOSE PROGRAM
( 4 ) ( 5 ) ( 6 ) ( PGM ) = SAVING MODE
N1 ( 1 ) (2ND ) ( 0 ) = WAIT for OUTSIDE MODE
( Î ) = SAVE STEP N°.1
N2 ( 9 ) ( 0 ) ( 0 ) ( 0 ) (BAS) = DEGREES FORWARD
( Î ) = SAVE STEP N°.2
N3 ( FPG ) = STOP PROGRAM
( Î ) = SAVE STEP N°.3
( FPG ) ( ALT ) (2ND ) (2ND ) = To EXIT " SAVING " mode
Now the program is SAVED.
Then we can recall program No.7 and start " AUTOMATIC " mode.
TYPE :
( 7 ) (2ND ) ( 1 ) ( Î ) = To RECALL PROGRAM N°.7
(2ND ) ( PGM ) = AUTOMATIC MODE
At this point, when the external start contact will close, you will get a rotation of 90 degrees and the
program stops.
It would be helpful, at this point, to carry out the same rotation of 90 degrees for 4 times, every time
that the start contact is closed.
For this purpose you use the function of : " N° of REPETION " and " SKIP PROGRAM ".
3. Then we can choose a free program, for example N° 5, and we plan a process that carries out a
rotation 90 degrees every time that the start contact is closed and we conclude the program
after this 4 rotations .
TYPE :
( 5 ) (2ND ) ( 1 ) ( Î ) = PROGRAM CHOICE
( 4 ) ( 5 ) ( 6 ) ( PGM ) = SAVING MODE
N1 ( 4 ) (2ND ) ( 9 ) = REPETITION NUMBER
( Î ) = SAVE STEP N°.1
N2 ( 9 ) ( 0 ) ( 0 ) ( 0 ) ( ANG ) = FORWARD DEGREES
( Î ) = SAVE STEP N°.2
N3 ( 2 ) (2ND ) ( 1 ) = SKIP PROGRAM N°.2
( Î ) = SAVE STEP N°.3
N4 ( FPG ) = STOP PROGRAM
( Î ) = SAVE STEP N°.4
( FPG ) ( ALT ) (2ND ) (2ND ) = To EXIT from SAVING MODE
13
At this point you can begin with this program that carries out a rotation of 90 degrees for 4 times
after closing the start contact then it stops.
TYPE :
( 5 ) (2ND ) ( 1 ) ( Î ) = To RECALL PROGRAM N°.5
(2ND ) ( PGM ) = START " AUTOMATIC " MODE
If you want to repeat a program every time you want you need to use this structure (FORM)
STEP " N - 1 " NUMBER of RIPETITIONS .
(2ND ) ( 9 )
STEP " N " ISTRUCTIONS that YOU WANT to REPEAT
STEP " N + " SKIP to STEP " N° "
(2ND ) ( 1 )
CONTINUE the PROGRAM and the EVENTUAL other I
ISTRUCTIONS of REPETITIONS .
( FPG ) STOP PROGRAM
Let's see a program with all functions you need to work on a machine tool with "M Function ".
4. We choose a free program, for example N°.1, we plan a process that carries out 4 indexings
clockwise and in absolute goes to 155 degrees, in incremental moves of 90 degrees counter clockwise and then return to 0 degree in absolute. Return at the beginning of the program, ready
to carry out an other piece.

piece )
N13 ( FPG ) ( Î ) = STOP PROGRAM

INFORMATION RESERVED to SERVICE
There are some parameter that you can set once at the installation of the control and the RAM on a
particular code.
They are :
1. Locking or not locking of the indexing head .
2. Break time after unlocking before the rotation .
3. Duration of rotation signal OK .
You can plan this parameter typing these keys :
( 7 ) ( 8 ) ( 9 ) (2ND) ( 1 ) ( Î ) ( 4 ) ( 5 ) ( 6 ) ( PGM )
212300
With this sequence of key you can write a program in which the 1° value defines the 3 above-
mentioned
functions as follow :
1. First digit 1 = NO LOCKING
2 = LOCKING
2. Second digit From 0 to 9 step 100 MS defined the delay after the unlocking and before the
rotation.
3. Third digit From 1 to 9 step 100 MS defined the duration of rotation signal OK .
4. Fourth digit From 0 = NO ENCODER.
3 = MAX ERROR ENCODER ( 1-9 STEP), ENCODER ABILITED
** N.B.**
At this moment you can verify or change the saved program. If you see on the display something else
or the display is clear. Type any key until you see the above-mentioned code the you can act as said
above.
In this way You can read the operation precedingly carried out . It is possible, for reason that we don' t
list, that the file don' t correspond to the normal programming. In this case it will display nothing.
But as soon as You type a numerical figure, it will appear the number of program, the number of file
and
the operations will usually carry out.
18
INSTRUCTION TO CLEAN THE MEMORY :
Attention ! ! ! ! ! In this way you cancel all the program and all the table parameter.
Use this operation only if really necessary.

INTERFACING and CONNECTION to the CNC MACHINE TOOL with
OWN UNITY of STEPPING CONTROL
MODEL.................../ I by " M FUNCTION "
CABLES CONNECTION TO THE "M FUNCTION " CONNECTOR .
1. The Table accepts, as machine tool start, a clean signal of " Zero Volt " obtained with a relay
installed in electrical box of machine tool.
2. When the Table has carried out the programmed positioning, it gives back a clean signal of
" Zero Volt " to the machine tool showing the correct positioning.
This signal is obtained by a relay in the electrical box of the Table.
3. Connect the 4 wires of " M Function " cable, that comes from the connector ILME C2 to the
electrical box of the machine tool.
- C2 supply solenoid valve connector, lock/unlock table, 220 Volt suppy and " M Function ".
4. Connect the wire STR 1 ( BROWN ) and STR 2 ( BLUE ) to the start Table signal coming from
machine tool.
Connect the wire ROK 1 ( BLACK ) and ROK 2 ( YELLOW-GREEN ) to the "Table in
position
signal ", from the machine tool.
5. Exchange time of " M Function " between the Table and the machine tool are 200 millisecond
like our standard. It is also possible to ast for higher or lower exchange times.
Now insert a program in the CNC Table and make the machine tool execute the program in manual
mode step by step.
ATTENTION !!!!
Do not insert in the table program the TIMED WELL ... A5, otherwise the table won't wait for the
start
machine tool signal, but it will wait for an inside timer.

INSTRUCTION of ENCODER CONTROL EQUIPMENT
For enabling the control from encoder you have to set the 4th DIGIT of the Customizing Parameter in
the following way :
0 = CONTROL ENCODER DISABLED
From 1 to 9 = ACCEPTANCE ERROR ENCODER VALUE
The acceptance unit is a function of the transmission ratio .
Example the ratio 1 : 120 the acceptance unit is 0,75 Hundredths .
At the end of the Zero research, if the encoder control is enable, it will appear " ERROR ENCODER "
as a checking of the real functionality of the control .
After the zero research it is necessary to set the actual " ZERO " in that position with the function :
( 0 ) (2ND ) ( 8 ) .
It is possible to see the position of the encoder in real time, if you need a check, with the function :
( OUT ) ( Î ) .
In this condition the position of the encoder is always displayed to make possible the Manual
Positioning .
To esc, TYPE : ( FPG ) .

MAIN RIGGING FOR USE OF THE CNC TABLE
MODEL TEC / I .
1. CONNECTION AND IGNITION TABLE :
First, connect the connectors ILME at the CNC table, the military connector at the table, the cable
with 4
wires of the " M Function " to the CNC Machine Tool, the solenoid valve connector of the
hydropneumatic gear case and at the end the supply cable to the electrical plug 220 V.
Connect the hydraulic cable to the table and the " PNEUMATIC " supply to the hydropneumatic
gear case through the our treatment group ( Yellow of Waircom, screw thread 1/8 Gas ) .
To turn on the CNC table disconnect in counter-clockwise the " EMERGENCY KEY " ( Red ) and
wait
that the CNC positioning does his SELF-DIAGNOSTIC .
When the display shows " Mecc. SCOTTI ", at this point the table is ready to use in MANUAL
WAY.
2. RESET TABLE AND MOVEMENTS OF CENTERING PIECE :
In manual way it is possible to carry out every mode of positioning :
For example :
To move of 30 degrees in clockwise in INCREMENTAL, type :
( 3 ) ( 0 ) ( 0 ) ( 0 ) ( ANG ) ( Î )
Every time you push ( Î ) the table carry out 30 degrees incremental forward .
To move of 30 degrees in counter-clockwise in INCREMENTAL, type :
( 3 ) ( 0 ) ( 0 ) ( 0 ) (2ND ) ( ANG ) ( Î )
Every time you push ( Î ) the table carry out 30 degrees incremental backward .
To carry the table in ZERO PIECE position, for resetting table, you have to make a lot of little
movement
of 100 / 10 / 1 degree or 0,10 / 0,01 of degree to reach the zero piece and then you set the zero typing:
( 0 ) (2ND ) ( 8 ) ( Î )
At this point the table is RESETTED and until you need an other zero piece you don' t need to repeat
this operation and also after the TURNING OFF and ON the TABLE; the zero is always stored.
To move of 30 degrees in ABSOLUTE, type :
( 3 ) ( 0 ) ( 0 ) ( 0 ) (2ND ) ( 7 ) ( Î )
In absolute you have to set the position only one time, and only in this particular case, the table choose
the shortest way to position it self .
N.B. : All there Manual and Program positioning, are all REPERRED TO THE ZERO PIECE
24
made in this way :
( 0 ) (2ND ) ( 8 ) ( Î ) .
3. TO CARRY OUT THE PROGRAM :
To carry out the program in manual way type :
( FPG ) (ALT) (2ND ) (2ND )
After :
( 1 ) (2ND ) ( 1 ) ( Î ) = Recall the program N° 1
(2ND ) ( PGM ) = START TABLE
To exit the program :
( FPG ) ( ALT) (2ND ) (2ND ) = Exit from program in automatic execution .
