7. Feed Functions

7.1 Rapid traverse rate

Function and purpose
The rapid traverse rate can be set independently for each axis. The available speed ranges are
from 1 mm/min to 1,000,000 mm/min for input setting units of 1µm. The upper limit is subject to the
restrictions imposed by the machine specifications.
Refer to the specifications manual of the machine for the rapid traverse rate settings.
The feedrate is valid for the G00, G27, G28, G29, G30 and G60 commands.
Two paths are available for positioning: the interpolation type where the area from the start point to
the end point is linearly interpolated or the non-interpolation type where movement proceeds at the
maximum speed of each axis. The type is selected with parameter "#1086 G0Intp". The positioning
time is the same for each type.

7.2 Cutting feed rate

Function and purpose
The cutting feedrate is assigned with address F and 8 digits (F8-digit direct designation).
The F8 digits are assigned with a decimal point for a 5-digit integer and a 3-digit fraction. The
cutting feedrate is valid for the G01, G02, G03 and G33 commands.
