Command Description
Parameters
Down Speed
: The speed at which the dispensing head descends to the point where
dispensing begins.
Up Speed
: The speed at which the dispensing head goes up after each dispense.
Acceleration
: The rate at which the dispensing head reaches the designated Down
Speed or Up Speed.
Max. Search Depth
: The maximum distance that the dispensing head descends
from absolute zero when searching for the substrate surface. If the height sensor
does not locate the surface within that distance, an error message appears. The
recommended setting varies depending on the application and platform.
Retract Distance
: The vertical distance the dispensing head moves up after
dispensing. The Retract Distance must be within the Safe Z Height and can be
reduced to increase dispensing speed. The recommended setting varies depending
on the application and platform.
Retract Before Height Sense
: Applies only to the Tactile (RT) Height Sensor. If
checked, the Z head is retracted to the safe Z position before each height sensing
action. This is used to insure that the Z head downward move reaches full speed
during height sensing to improve accuracy. Using this feature will cause an increase
in production throughput time because of the retract time required.
