4. DESCRIPTION OF PARAMETERS
B–63010EN/02
74
NOTE
1 This parameter is effective only in linear and circular
interpolation. In polar coordinate, cylindrical, and involute
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.
3 In a mode other than the AI contour control mode or
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.
4 In the HPCC mode, if values are specified in both
parameters No. 1430 and No. 1432, the setting of parameter
No. 1432 takes priority. If nothing is specified in parameter
No. 1430, the feedrate is clamped to the value specified in
parameter No. 1422.
1450
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)
