Example of changing traverse command for the same axis:
Program code Comments
ID=1 EVERY $A_IN[1]>=1 DO POS[V]=100 FA[V]=560 ; Start positioning from synchronized
action, if digital >= 1
ID=2 EVERY $A_IN[2]>=1 DO POS[V]=$AA_IM[V] FA[V]=790 ;
xis tracks, the 2nd input is set, i.e.
end position and feedrate for axis V,
for two synchronized actions
simultaneously active, is tracked on-
the-fly while moving.
10.4.19 Set actual values (PRESETON)
Function
When PRESETON (axis, value) is executed, the current axis position is not changed but a
new value is assigned to it.
PRESETON from synchronized actions can be programmed for
● modulo rotary axes that have been started from the part program and
● all command axes that have been started from a synchronized action
Syntax
DO PRESETON(axis, value)
Significance
DO PRESETON
Setting actual values in synchronized actions
Axis
Axis of which the control zero is to be changed
Value
The value by which the control zero is to be changed
Restrictions for axes
PRESETON cannot be programmed for axes, which are involved in a transformation.
One and the same axis can by moved from the part program and from a synchronized
action, only at different times. For this reason, delays can occur in the programming of an
axis from the part program if the same axis has been program in a synchronized action first.
If the same axis is used alternately, transfer between the two axis movements is
coordinated. Part program execution must be interrupted for that.
