4. DESCRIPTION OF PARAMETERS
B–63610EN/01
68
NOTE
1 This parameter is valid only during linear interpolation and
circular interpolation. Even when this parameter is set,
clamping to a maximum cutting feedrate based on
parameter No. 1422 is enabled during polar coordinate
interpolation, cylindrical interpolation, and involute
interpolation (M series).
2 When this parameter is set to 0 for all axes, clamping to a
maximum cutting feedrate based on parameter No. 1422 is
enabled.
This means that if a value other than 0 is set for any of the axes
with this parameter, clamping to a maximum cutting feedrate
is performed for all axes during linear interpolation or circular
interpolation according to this parameter.

Specify the maximum cutting feedrate for all axes in the look–ahead
control mode.
A feedrate in the tangential direction is clamped in cutting feed so that it
does not exceed the feedrate specified in this parameter.
NOTE
1 To specify the maximum cutting feedrate for each axis, use
parameter No.1432 instead.
2 In a mode other than the look–ahead mode, the maximum
cutting feedrate specified in parameter No.1422 or No.1430
is applied and the feedrate is clamped at the maximum
feedrate.
