8.2.6 Setting and Operation of 3-Axis Spiral Interpolation
In the following example, an arc is drawn with the 1st axis (X-axis) and 2nd axis (Y-axis), and
a 3-axis spiral interpolation control is performed with 3rd axis (Z-axis) movement.
10000 pulses
5000 pulses
20000 pulses
Center point (X axis: 0, Y axis: 10000)
(Ｘ axis)
1st axis
(Y axis)
2nd axis
(Z axis)
3rd axis
Settings
Item Setting example Remarks
Operation pattern E: End point
Interpolation operation
E: Spiral (Center point/CW
direction/3rd axis movement)
Control method I: Increment
1st axis (L) movement amount 0 pulse
Axis numbers are put in (L) and (m).
For the auxiliary points, specify the
coordinate (0, 10000) to be the center
of an arc.
1st axis (L) auxiliary point 0 pulse
2nd axis (m) movement amount 20000 pulses
2nd axis (m) auxiliary point 10000 pulses
3rd axis (n) movement amount 5000 pulses Axis numbers are put in (n).
Specify the movement amount of 3rd
axis (Z-axis).
3rd axis (n) auxiliary point 0 pulse
Acceleration/deceleration type L: Linear
Acceleration time (ms) 100 ms
Deceleration time (ms) 100 ms
Interpolation speed 10000 pps
