Linear Interpolation Speed
Interpolated path speed designation
Maximum speed designation
You can select the speed of each axis during linear interpolation via [Interpolation Speed
Specification Method] of the sequence data.
Under [Interpolation Speed Specification Method], specify [Specify Interpolation Path Speed]
or [Maximum Speed Specification].
Although the interpolated path speed conforms to [Interpolation Speed] of the sequence data,
the speed of each axis is determined by the calculation formulas below (the same calculation
formulas also apply to linear interpolation that involves 2 or 3 axes).
Example) Simultaneous linear interpolation of 4 axes
Speed of axis 1 = Interpolation speed × Movement of axis 1 / Total movement
Speed of axis 2 = Interpolation speed × Movement of axis 2 / Total movement
Speed of axis 3 = Interpolation speed × Movement of axis 3 / Total movement
Speed of axis 4 = Interpolation speed × Movement of axis 4 / Total movement
Total movement = Axis 1 movement
If you break down the interpolation speed into the speed of each axis according to the above
formulas and that speed exceeds the [Maximum Speed] parameter of the applicable axis, the
interpolation speed is automatically lowered so that you can operate any of the axes that
perform linear interpolation at the maximum speed.
Automatically calculate the interpolation speed so that you can operate any of the axes at the
[Maximum Speed] of the axis parameter.
Under this specification, [Interpolation Speed] of the sequence data is disabled.
