CREATING POSITIONING PROGRAMS

Enter the menu

by the keys PGM and RESET/ENTER. Select the first dimension of the positioning

program by pressing the key

and set its value according to the description of the previous paragraph.

To control the inserted program you only have to enter the menu

and run

through the sequence

of program steps: for the end of program dimensions the display will show the writing "

SETTING OF NUMBER OF CYCLES

The number of cycles means the number of times the program will be executed. In the automatic working

mode, if the number of cycles is more than 1, once the last dimension of the positioning program has been

executed, the positioner restarts from the first dimension of the chosen program when the piececounter input

is activated again.

To set the number of cycles enter programming mode and go to

by the keys PGM,

, and

RESET/ENTER. Set up the required value ) and confirm it by the key RESET/ENTER.

SETTING UP OF MACHINERY CONSTANTS

Enter on programming and move to the menu

for machinery constant, press RESET/ENTER and the

number 000 will be displayed, the first digit from the right will be flashing you are now supposed to insert the

password; insert the number 273 and confirm by RESET/ENTER. In case of wrong password the instrument

leave the programming mode. By pressing the key

you can run trought the constants; which are kept

visible for about 2 seconds, after a while their current value appears. To modify it press RESET/ENTER and

use the keys

and

. Once the required value has been inserted, confirm it by RESET/ENTER.

: in this phase if you not press keys for more of 10 seconds the instrument leave the programming

ATENTION

mode.

The machinery constant of the positioner are the followings:

• Blade Thickness

By setting a not zero value all the positioning dimensions were set will be increased with this quantity. These

constant is used the aplicatios witch expect a cut with material removal.

• PreStop

It represents the inertia of positioned axis; the positioner disables the start output when the axis reaches a

dimension equal to the difference between the set dimension and the PreStop value. This constant allows to

compensate for the positioning inertia in steady inertia systems. It is suggested to set the PreStop value after

setting all the other machine constants. In order to obtain the correct PreStop value it is necessary to carry out

a positioning and find out the difference between the set dimension and the actually obtained dimension.

• Dimension of slow motion

The positioner starts the slow output when the axis reaches a dimension equal to the difference between the

set dimension and Slow Motion. By setting up 0 value the slow output is always disabled (the motion is always

fast).

• Absolute/Line working procedure

In Absolute working mode all the set dimensions refer to absolute zero, whereas in Line working procedure the

set dimensions refer to the last executed positioning, which means that the instrument resets the current

dimension before starting each positioning.

• Automatic/Semiautomatic Working mode

In the Automatic procedure, (setting A), the positioning starts when the START input changes over from open

to closed; following positionings carry on automatically as long as the START input remains in the closed

condition. Automatic execution stops as soon as the START input changes over from closed to open.

In the Semiautomatic procedure, (setting S), positioning starts when the START input changes over from

open to closed : once the arrival dimension has been reached execution stops and starts again only if the

START input changes over from open to closed.
