AUX output enabling
output not enabled (default),
-
--
-
the output is enabled when the set dimension is reached,
+
++
+
the output is enabled when the set number of parts is reached.
For every programme step it is possible to decide whether enabling the AUX
output when the set dimension is reached, or when the set number of parts
is reached, or not. In case the decision to enable the AUX output is made,
the output remains enabled for all the time set in the
/0
constant (see
page 6).
End of programme
the dimension corresponds to one step of the programme (default),
the dimension corresponds to the end of the programme.
This constant enables to attribute to the current dimension the end of the
programme.
Absolute/relative dimension
the set dimension is absolute (default),
.
..
.
the set dimension is relative.
The set value for the dimension to be processed can be expressed either in
an absolute way, that is it may be referred to the axis zero point, or in a
relative way, that is it may be referred to the current position of the axis.
In order to change the previous constant values use the
START
- key to switch from one value to the other
and the
STOP
+
key to switch to the following constant. After setting all the wished values, confirm through
the
E
key.

SETTING OF POSITIONER MACHINE PARAMETERS (COST)
Through this function all the machine constants that adjust the positioner functioning may be entered. In
order to modify the constants the password
273
is always needed. Then all the constants are described.
1) Blade thickness
If a value other than zero is set all the set positioning dimensions will be increased by that value. This
constant is used for the applications that need cutting with material removal.
2) PreStop
/
/
/
/
The positioner stops the axis movement when it reaches the dimension amounting to the difference
between the set dimension and the PreStop value. This parameter enables to counterbalance the
positioning inertia in systems with constant inertia. It is advisable to enter the PreStop parameter after
setting all the other machine constants. In order to obtain the correct PreStop value it is necessary to
carry out a positioning and to calculate the difference between the set dimension and the dimension being
actually reached by the axis.
3) Slow dimension
-+/
-+/
-+/
-+/
The positioner enables the slow output when the axis reaches a dimension amounting to the difference
between the set dimension and the Slow dimension. By setting the zero value, the Slow output is always
disabled (the movement is always in the fast mode).
4) Absolute/Line functioning mode
+
+
+
+
In the Absolute functioning mode (setting A) all the set dimensions are referred to the absolute zero, while
in the Line mode (setting L) the set dimensions are related to the last carried out positioning; that is the
instrument zero sets the current dimension before carrying out any positioning.
5) Automatic/Semiautomatic functioning mode
0/
0/
0/
0/
In the Automatic functioning mode (setting A) the beginning of the positioning is determined by the
switchover of the START input from open to closed; the following positioning operations are automatically
carried out for all the time during which the START input remains closed. The automatic process is
stopped when the START input is opened.
In the Semiautomatic functioning (setting S) the positioning starts with the switchover of the START input
from open to closed: after reaching the target dimension the process is stopped and only restarts if the
START input switches from open to closed.
