7.1 Rapid Traverse Rate

Function and purpose
The rapid traverse rate can be set independently with parameters for each axis. The available
speed ranges are from 1 mm/min to 10000000 mm/min. 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.
If the high-accuracy control mode's rapid traverse rate is set, the axis will move at that feed rate
during high-accuracy control, high-speed high-accuracy control I/II, high-accuracy spline control or
SSS control.
• If the value set for the high-accuracy control mode rapid traverse rate is 0, the axis will move at
the rapid traverse rate.
• The high-accuracy control mode rapid traverse rate can be set independently for each axis.
• The high-accuracy control mode rapid traverse rate is effective for the G00, G27, G28, G29, G30
and G60 commands.
• Override can be applied on the high-accuracy control mode rapid traverse rate using the external
signal supplied.

7.2 Cutting Feedrate

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, G02.1 and G03.1 commands.
If the high-accuracy control mode's cutting clamp speed is set, the cutting feed rate will be clamped
at that feedrate during high-accuracy control, high-speed high-accuracy control, high-accuracy
spline control or SSS control.
• If the value set for the high-accuracy control mode cutting clamp speed is 0, the axis will be
clamped at the cutting feed clamp speed.
• The cutting feedrate is clamped with high-accuracy control mode cutting clamp speed in the
parameter.
