8.2 Interpolation Control

Type of perations
For the interpolation control, there are 2-axis linear interpolation control, 2-axis circular interpolation
control, 3-axis linear interpolation control, and 3-axis spiral interpolation control. The following methods
are available to specify the operation of each interpolation control. Select any of them as usage. The
axes in the relation of an interpolation are called X axis and Y axis for the 2-axis interpolation, and are
called X axis, Y axis and Z axis for the 3-axis interpolation. Also, X, Y, Z axes are automatically allocated
from the smallest axis number.
In each interpolation control, the E point control tha tuses one table, P point control and C point control
that uses multiple tables can be combined arbitrarily as positioning data.
For example, using the P point control enables the continuous interpolation control from the 2-axis linear
control to the 2-axis circular interpolation control. The acceleration time and deceleration time can be
specified individually. For the P point control and C point control, the E point should be set as the last
table.
