Positional deviation: 200 mV 10 ms
Force signal: 5 V 10 ms

Vtarget: 5 V 10 ms
After reaching the circuit board, the lower light barrier is activated (the forced air is immediately
switched on).
The additional wait time starts to count down once this point in time has been reached.
In the placement profile for the Z-axis the axis continues to move about 6 digits after reaching
the placement height when in the light barrier mode to ensure full contact with the component.
About 2 to 3 seconds of system time must be added to the wait time programmed.
An additional wait time can be programmed when bare dies are to be placed in adhesive. In this
case the component will be pressed into the adhesive with the programmed placement force.
Can be combined as desired with all other placement modes.
