Each of these parameters is used to set a position control loop gain for
the spindle and tapping axis in rigid tapping. These parameters
significantly affect the precision of threading. Conduct cutting tests,
and make adjustments to obtain an optimum value.
When performing threading with an analog spindle, also adjust the
loop gain multipliers (parameter Nos. 5291 to 5294).
NOTE
1 To use a varied loop gain on a gear-by-gear basis,
set parameter No.5280 to 0, and set a loop gain for
each gear in parameters No.5281 through
No.5284. The specification of a loop gain on a
gear-by-gear basis is disabled if parameter
No.5280 is set to a value other than 0. In such a
case, the value set in parameter No.5280 is used
as a loop gain that is common to all the gears.

No.5204) is set to 0, the setting of parameter
No.5280 or the settings of parameters No.5281

In polar coordinate interpolation mode, automatic override operation

NOTE
In polar coordinate interpolation mode, the feedrate
component for a rotational axis increases as the
tool moves closer to the center of a workpiece.
Near the center of a workpiece, the maximum
cutting feedrate (parameter No.5462) may be
exceeded, causing servo alarm No.411 to be
issued. The automatic feedrate override function
and automatic feedrate clamp function
automatically control the feedrate to prevent the
feedrate component on a rotation axis from

4.DESCRIPTION OF PARAMETERS
B-64120EN/01
This parameter sets the upper limit of the cutting feedrate that is
effective during polar coordinate interpolation. If a feedrate greater
than the maximum feedrate is specified during polar coordinate
interpolation, it is clamped to the feedrate specified by the parameter.
When the setting is
0, the feedrate during polar coordinate
interpolation is clamped to the maximum cutting feedrate usually
specified with parameter 1422.

[Data type]

[Unit of data]

[Valid data range]
0 to 100
This parameter sets an allowable percentage to find an allowable
feedrate on a rotation axis in polar coordinate interpolation mode. A
maximum cutting feedrate (parameter No.5462), multiplied by the
allowable percentage set with this parameter represents an allowable
feedrate.
Allowable feedrate
= maximum cutting
× allowable percentage
on rotation axis
feedrate
In polar coordinate interpolation mode, the feedrate component on a
rotation axis increases as the tool moves closer to the center of a
workpiece. Near the center of a workpiece, the maximum allowable
feedrate
(parameter No.5462) may be exceeded. To prevent the
feedrate component on a rotation axis from exceeding the maximum
allowable feedrate in polar coordinate interpolation mode, the
following override is automatically applied to the feedrate (automatic
override):
Allowable feedrate on rotation axis
Override
=
×
100 (%)
Feedrate component on rotation axis
If the overridden feedrate component for a rotation axis still exceeds
the allowable feedrate, the feedrate is clamped to prevent the feedrate
component on a rotation axis from exceeding a maximum cutting
feedrate (automatic feedrate clamp).
NOTE
When 0 is set in this parameter, a specification of
90% is assumed. When a value of 100 or greater is
set with this parameter, a specification of 100% is
assumed. Before the automatic override function
and automatic feedrate clamp function can be
used, bit 1 (AFC) of parameter No.5450 must be
set to

cutter compensation is specified during normal direction control in the

When normal direction control is applied, the amount of movement
(rotation angle) on the normal direction control axis
(C-axis),
calculated so that the C-axis is directed at right angles to the direction
of motion at the start point of a block, may be smaller than the value
specified in this parameter. In such a case, the C-axis movement is
not inserted before the movement
(along the X-axis and Y-axis)
specified by the block. Instead, the C-axis movement is performed
together with the movement specified by the block. If the amount of
movement (rotation angle) on the C-axis is greater than or equal to the
value specified with this parameter, the C-axis movement is inserted,
and the movement specified by the block is made after the completion
of the C-axis movement.
NOTE
This parameter is enabled when the SDC
parameter (bit 0 of parameter No.5484) is set to 1.
If a value equal to or greater than 180 degrees is
specified, a C-axis movement is inserted only when
circular interpolation involving a C-axis rotation of
180 degrees or more is performed.
