Species the height to which the dispensing tip raises after each dispense command. The purpose of
ZClearance is to raise the tip high enough so that it clears all obstacles as it moves from one point to
another. If there are no obstacles between any of the points, a small Z-clearance value, such as 5mm, can
be used to minimize the program cycle time.
ZClearance is further dened as a relative value (0) or an absolute value (1) . When specied as a relative
value, it is the distance the tip raises relative to the taught point location. When it is specied as an absolute
value, it is the distance from the Z-axis zero position to which the tip raises regardless of the Z-axis value of
the taught point location.
Nordson EFD recommends inserting a ZClearance command at the beginning of a program.
