AUTOMATIC/SEMIAUTOMATIC POSITIONING (A/S)

The automatic/semiautomatic function carries out the selected programme.  The programme selection
can be obtained in 2 ways:

-  Press the  

C

  key and insert in display 3 the index of the dimension corresponding to the first step of

the programme to be carried out then confirm with 

E

  or,

- Press the 

C

  key and select through the + and – keys the first dimension of the programme and

confirm with 

E

.

Once selected the programme, display 3 will show the index of the dimension while on display 2 the
corresponding dimension will be displayed.
To start the positioning close the  

START

 input in the terminal box or hold down the 

START

- key for about  2

seconds. The axis will shift towards the first dimension of the programme and when reached it the axis
will be stopped and the end of positioning output will be enabled for a time equal to that set in the 

//

constant (see page 6).  Before going on with the subsequent dimensions the positioner waits for the
enabling of the 

WORK COUNTER 

and 

START

 inputs according to what was set in the machine

 /

constants (see page 55).

By pressing the 

STOP

+ key it is possible to interrupt the positioning; to resume it press 

START

- for 2

seconds or close the 

START

 input or open the emergency input to quit the positioning programme.

As to the writing of the dimension programmes see the following paragraph.

WRITING OF DIMENSIONS AND POSITIONING PROGRAMMES  (PROG)

By programme we mean a series of dimensions to be executed in sequence where, for every dimension,
it is possible to set the number of parts to be processed and the enabling of the auxiliary output 

AUX

.

The positioner can memorize 99 dimensions that may be organised into positioning programmes.  The
length of the single programmes is limited only by the total number of memorised dimensions, which must
not exceed 99 (for instance it is possible to create as ultimate limits either  99 programmes made by a
single dimension or one single programme made by  99 dimensions).
The modification of the dimensions is protected by a password; the password is requested through the
display of letter P on display3 and of three zeroes (the first one of them is blinking) on display2.  Enter the
number 

273

  and confirm with  

E

.  In case of wrong password entry the instrument leaves the

programming phase.  The request of the password in order to have access to the programme dimensions
may be excluded by opportunely setting the 

-

  constant (see on page 7).

Dimension setting

Display3 shows the programme index (or programme step) of the current dimension (from 1 to 99), the
display2 shows the value of the wished dimension and the display4 the  

-/

  writing.

To select the dimension which is to be modified there are two modes: with the  

START

- and 

STOP

+ keys it

is possible to scroll all the dimensions in sequence and to select the dimension to be modified or to press
the  

C

 key for about 2 seconds until the dimension index on display3 starts blinking; then introduce the

value of the dimension index that is to be modified and confirm with the 

E

 key.

After selecting the dimension to be modified, press the  

C

 key,  enter the wished numerical value and

confirm with  

E

.

Setting of the number of pieces

Then the programme will make the request of the number of parts to be processed in sequence; display4
will display the  

+

  

writing, press the 

C

 key, enter the wished number of pieces and confirm with  

E

.

NB: If a number of pieces=0 is set, the positioner does not wait for the enabling of the 

PIECES COUNTER

input to carry on with the positioning at the subsequent dimension.

Setting of the kind of dimension, of the end of programme and of the enabling of the auxiliary
output

After the number of parts it is necessary to programme the dimension mode constants; display4 will
display the  

  writing while display2 will show the following:
