11.2 Interpolation Control

11.2.1 Interpolation Control Types

 Operation types
• 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.
