Beginning Programming 6-33
Item Description
Retract Distance
This is a vertical distance that the dispensing head moves after the
Backtrack Gap and Backtrack Length dispensing commands have
completed. Figure 6-20 shows the relationship between Retract Distance,
Backtrack Gap and Backtrack Length. The Retract Distance must be within
the Safe-Z Height defined in Initial Setup. The units are inches. Typically,
250 mils (0.250 inch) is sufficient.
Retract Speed
This is the speed of the dispensing head while moving the Retract
Distance. The units are in inches/second. Typically, 2 in/sec is sufficient.
Retract
Acceleration
This is the parameter that controls how fast the dispensing head comes up
to the Retract Speed. You may need to set this high for small dispensing
moves. The units are inches/second2. Typically, 300 in/sec2 is sufficient.
