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 ".

KEY MEANING :

1. Dividually pushed :

(1) = 1 (2) = 2 (3) = 3 (4) = 4

(5) = 5 (6) = 6 (7) = 7 (8) = 8

(9) = 9 (0) = 0

(2ND)(FPG) ( A ) ( # ) = DON'T USED

(2ND)(ALT) ( A ) ( −) = DON'T USED

*(0) (2ND)(7)

( 0 ) ( A ) ( 7 ) = RETURN to ZERO PIECE

(Angle value) (2ND)(7) (Angle value) (A) (7)= ABSOLUTE POSITIONING

(1) (2ND) (8) ( 1 ) ( A ) ( 8 ) = RESET TABLE AXIS ( Mechanical Zero ).

( 0 ) (2ND) ( 8 ) ( 0 ) ( A ) ( 8 ) = SET ZERO PIECE ( Rest Display ).

KEY MEANING :

1. Individually type:

(1) = 1 (2) = 2 (3) = 3 (4) = 4

(5) = 5 (6) = 6 (7) = 7 (8) = 8

(9) = 9 (0) = 0

(2ND)(2ND) = CANCEL VISUALIZATION

(2ND)(STP) = READ the PROGRAM AGAIN

(2ND)(OUT) = OUTPUT OFF

(2ND)(ANG) = NOT USED

(2ND)(PGM) = PROGRAM RUNNING

For Example :

* If you want to carry out a rotation of 90 degrees and 12 hundredths degrees .

TYPE : ( 9 ) ( 0 ) ( 1 ) ( 2 ) = NUMERICAL VALUE

( ANG ) = FUNCTION (Forward degrees) - (2ND)(ANG) =Backword

degrees

(Î) = EXECUTION

* If you want return to zero piece or reach an angle in absolute .

TYPE : ( 0 ) = NUMERICAL VALUE

( 2ND ) ( 7 ) = Function ( Return to Zero Piece )

(Î) = EXECUTION

* If you want to carry out the reset of table axis (Mechanical Zero) .

TYPE : ( 1 ) = NUMERICAL VALUE

( 2ND ) ( 8 ) = RESET FUNCTION

(Î) = EXECUTION

* If you want to set " Zero Piece " position .

TYPE : ( 0 ) = NUMERICAL VALUE

( 2ND ) ( 8 ) = RETURN TO ZERO

(Î) = EXECUTION

* If you want to carry out a rotation like 1/127 of 360 degrees .

TYPE : ( 1 ) ( 2 ) ( 7 ) = NUMERICAL VALUE

( 2ND ) ( 3 ) = Function ( FORWARD DEGREES )

(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

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.

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 4years) .

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.
