Z Clearance
The purpose of the Z Clearance function is to cause the tip to raise high enough to clear
all obstacles as it moves from one point to another. If there are no obstacles between any
of the program points, a small Z Clearance value, such as 5 mm, can be used to minimize
the program cycle time.
Values for the
Z Clearance
are registered by pressing the
F4 (Setup)
key, then choosing
Z Clearance.
The
Z Clearance
value will be used by all points from that memory address
forward until another
Z Clearance
value is found. Normally, a Z clearance instruction
should be registered in the beginning of a program, at one of the first memory addresses.
The Z Clearance value may be specified as a relative value or an absolute value. When
specified as a relative value, it is the distance to rise relative to the taught point location.
When it is specified as an absolute value, it is a distance from the Z-axis zero position,
where the tip will rise to, regardless of the Z-axis value of the taught point location. For
example:
Z Clearance = 10 mm RELATIVE:
10 mm
Z = 0 mm
