4. DESCRIPTION OF PARAMETERS
B–63840EN/03
58
Specify the maximum cutting feedrate for each axis in the AI advanced
preview control/AI contonr control mode, or advanced preview 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.
NOTE
1 This parameter is effective only in linear and circular
interpolation during advanced preview control mode. In
cylindrical interpolation, 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 during advanced
preview control mode.
3 The maximum cutting feedrate in the AI advanced preview
control/AI contour control mode is the lowest value of
parameters No.1432, No.1422, and No.1420. When one of
these parameters is set to 0, however, alarm No.5157 is
applied.
4 In a mode other than the AI advanced preview control mode
or advanced preview control/AI contour 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.

Change of feedrate for one graduation on the manual pulse generator during F1
digit feed
[Data type] Byte
[Valid data range] 1 to 127
Set the constant that determines the change in feedrate as the manual pulse
generator is rotated one graduation during F1-digit feed.
F +
Fmaxi
100n
∆
(where, i=1 or 2)
In the above equation, set n. That is, the number of revolutions of the
manual pulse generator, required to reach feedrate Fmaxi is obtained.
Fmaxi refers to the upper limit of the feedrate for an F1-digit feed
command, and set it in parameter 1460 or 1461.
Fmax1: Upper limit of the feedrate for F1 to F4 (parameter 1460)
Fmax2: Upper limit of the feedrate for F5 to F9 (parameter 1461)
