Positional deviation: 2 V 20 ms
Force signal: 5 V 20 ms
Iactual: 5 V 20 ms
Vtarget: 5 V 20 ms
Calibrate the end signal from the oscilloscope memory.
With the "Pick-up without contact" option activated, the component was picked up at the calibrated
pick-up height.
Absolute positioning: The counting of the positional deviation below is not started.
The time spent over the component is the result of switching on the vacuum.
The force is only reduced during the braking phase.
The downward positioning operation takes about 25 ms
instead of 60 ms when calibrating.

Positional deviation: 200 mV 20 ms
Force signal: 5 V 20 ms
Iactual: 5 V 20 ms
Vtarget: 5 V 20 ms
End signal: 5 V 20 ms
"Contactless" mode 17 was used for pick-up here.
With the "Pick-up without contact" option activated, the height was calibrated during the first pick-
up operation
by pressing the component onto the PCB using force level 5 (about 55 digits).
Travel started at start speed for 44 digit path.
You can tell that the vacuum has been switched on when the light barrier is at the top due to
the wait time of about 2 ms on the component.
Combination for package forms that are to be picked up without contact, but that may fall off when
accelerating upwards due to their weight. The parameters do NOT affect each other. Can also be
combined with the "Early vacuum" option.

End signal from the oscilloscope memory
Absolute positioning: The counting of the positional deviation below is not started.
The time spent over the component is the result of switching on the vacuum.
The force is reduced during the braking phase
and also when beginning to move upwards.
The positioning operation takes about 25 ms when moving up.
