CREATING POSITIONING PROGRAMS
Enter the menu
-0/
-0/
-0/
-0/
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
-0/
-0/
-0/
-0/
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
.
ATENTION
:
in this phase if you not press keys for more of 10 seconds the instrument leave the programming
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
0/
0/
0/
0/
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
.
