Star station 9:
▪ Pickup cycle
The nozzle is rotated into the "pickup" position.
▪ Placement cycle
The component is rotated into the correct placement angle with the help of the DP axis.
Between star station 11&12
▪ The "presence" and "height" of the component at the nozzle is checked by the component sensor
(optional).
