Normal placement with light barriers. After switching on the forced air it takes about 20 ms until
the Z-axis accelerates up and away from the component.
Disadvantage: The placement operation takes about 20 ms longer.
This is a new programming capability. It corresponds to mode 3 "Slow start" when picking up a
component. Mode 10 "Slow start" can be selected so that the components remain securely on the
circuit board. In doing so, 44 digits (= 1mm) are traveled at the start speed. After that, it accelerates
and follows the normal speed profile.

The component is to be placed on the circuit board with more than 2 N of placement force. The
mode for the downward motion and the value for the placement force must always be set. The
placement operation is delayed until the current in the servo-amplifier has built up.

Positional deviation: 200 mV 10 ms
Force signal: 5 V 10 ms
Iactual: 5 V 10 ms
Vtarget: 5 V 10 ms
End signal from the oscilloscope memory
Mode 2 "With placement force" (power monitor mode) was used for placement in order to increase
the placement force to 3 N.
The end signal is delayed until the corresponding current in the servo-amplifier has built up.
Forced air is switched on during this extended positioning time.

Positional deviation that can be measured with the axis firmware on an HS-50/S-25HM when
the power monitor mode is active.
