Dispense Dot Setup
Click Function
Sets how the system dispenses a dot of fluid.
Parameter Description
Valve On Time How long the dispenser stays open (in seconds).
Dwell Time Delay time (in seconds) that occurs at the end of dispensing to allow the pressure to equalize
before the tip moves to the next point.
Head Time Delay time (in seconds) that occurs at the beginning of dispensing.
Dispense End Setup
Click Function
After dispensing a dot or line, it is often required to raise the tip a short distance at a slow speed. This allows the
fluid to cleanly break free from the tip to prevent it from being incorrectly applied. The parameters for Dispense
End Setup affect how far and how fast the tip raises after dispensing.
Parameter Description
Retract Low Speed The speed (inmm/s) at which the tip raises after dispensing.
Range: 0–150mm/s
Retract High Speed After the tip raises the amount specified by Retract Distance at the speed specified by
Retract Low Speed, the tip continues raising to the Z-clearance height at the speed
(inmm/s) specified by this setting. The purpose of specifying a Z-clearance height is to
allow the tip to raise high enough to clear any obstacles it encounters on the way to the
next point.
Range: 0–150mm/s
Retract Distance The distance (inmm) the tip raises after dispensing.

Dispenser Off / Dispenser On
Click Function
or
Turns the dispenser OFF or ON at the current address.
NOTE: This command is useful when you want to turn off (deactivate) dispensing for part of a line. To do
so, determine the beginning and end points where you want the line to be deactivated and then insert a
Dispenser Off command in between those points. When you want the line to be active, insert a Dispenser
On command between those points. An example program and the resulting pattern is shown below.

NOTE: The Path view in the
Secondary View screen will NOT
change when you add the Dispenser
Off / Dispenser On commands as
shown in this example; this image is
only a representation of the resulting
dispense pattern.
NOTE: This image is the actual
Path view of the example program
shown.
Dummy Point
Click Function
Registers the current XYZ location as a Dummy point. The dispensing tip passes through this point. A dummy
point is useful for avoiding obstacles on the workpiece.
Parameter Description
Speed The speed (inmm/s) at which the tip moves toward the dummy point.
Range: 0–150mm/s
