After you have completely set up the press system (with tools), you can
calculate the deflection. This can be done based upon a normal press
sequence.
 Select the "Curve Output" system function key.
 Press a workpiece and record the force/stroke curve.
 Enlarge the curve section so that the press start and press end are
visible.

 Calculate the deflection.
Sample calculation: Stroke difference ∆s = 2 mm
Force difference ∆F = 1,7 kN
Deflection ∆s/∆F = 1,176 mm/kN
