PRESETON(AXIS,VALUE,…)
Explanation of the commands
PRESETON
Set actual value
Axis
Machine axis parameter
Value
New actual value to apply to the specified axis
Function
In special applications, it can be necessary to assign
a new programmed actual value to one or more
axes at the current position (stationary).
Sequence
The actual values are assigned to the machine
coordinate system – the values refer to the machine
axes.
Example:
N10 G0 A760
N20 PRESETON(A1,60)
Axis A travels to position 760. At position 760, machine
axis A1 is assigned the new actual value 60.
From this point, positioning is performed in the new
actual value system.

Kinematic transformation
The reference point becomes invalid with the function
PRESETON. You should therefore only use this
function for axes which do not require a reference point.
If the original system is to be restored, the reference
point must be approached with G74 – see Section 3.1.
