Specify the maximum cutting feedrate for each axis in the look-ahead feed-forward control
mode.
A feedrate for each axis is clamped during cutting feed so that it does not exceed the
maximum cutting feedrate specified for each axis.
WARNING
In a mode other than the look-ahead feed-forward control mode, the maximum cutting
feedrate specified in parameter No.1422 or No.1430 is applied and the feedrate is
clamped at the maximum feedrate.
NOTE
1 This parameter is effective only in linear and circular interpolation. In polar
coordinate, the maximum feedrate for all axes specified in parameter No.1431 is
effective.
2 If a setting for each axis is 0, the maximum feedrate specified in parameter No.1431 is
applied to all axes and the feedrate is clamped at the maximum feedrate.

FWB Cutting feed acceleration/deceleration before interpolation
0: Type A of acceleration/deceleration before interpolation is used.
1: Type B of acceleration/deceleration before interpolation is used.
Type A: When a feedrate is changed by a command, acceleration/deceleration starts after the
program enters the block in which the command is specified.
Type B: When a feedrate is changed by a command, deceleration starts and terminates at the block
before the block in which the command is specified.
When a feedrate is changed by a command, acceleration starts after the program enters
the block in which the command is specified.
