7.2 Interpolation Control

7.2.1 Types of Interpolation Control

 Types of operations
Interpolation control includes 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 an
appropriate method according to the application. The axes in the relation of 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. X-, Y-, and Z-axes are automatically assigned in ascending order
of axis signal levels.
In each type of interpolation control, the E-point control that uses one table, P-point control
and C-point control that uses multiple tables can be combined arbitrarily as positioning data.
For example, using P-point control enables continuous interpolation control from 2-axis linear
control to 2-axis circular interpolation control. The acceleration time and deceleration time can
be specified individually. For P-point control and C-point control, an E point should be set as
the last table.
