8456 Area–2 override
[Data type] Word
[Unit of data]
%
[Valid data range] 0 to 100 (Standard setting: 80)
This parameter specifies an override in area 2 of velocity calculation considering
the cutting load.
8457 Area–3 override
[Data type] Word
[Unit of data]
%
[Valid data range] 0 to 100 (Standard setting: 70)
This parameter specifies an override in area 3 of velocity calculation considering
the cutting load.
8458 Area–4 override
[Data type] Word
[Unit of data]
%
[Valid data range] 0 to 100 (Standard setting: 60)
This parameter specifies an override in area 4 of velocity calculation considering
the cutting load.
8464 Initial feedrate for automatic feedrate control

Inch machine 0.1 inch/min
10
∼96000 1∼48000
Rotation axis 1 deg/min
10
∼240000 1∼100000
This parameter sets the initial feedrate for automatic feedrate control.
In automatic feedrate control, the initial feedrate set with this parameter is used
at the beginning if no F command is specified in the program.
Usually, set the maximum cutting feedrate (specified in parameter No. 1422).

This parameter sets the maximum allowable feedrate for automatic feedrate
control. Usually, set the maximum allowable cutting feedrate (set in parameter
No. 1422).
