Linear Interpolation
Section 9-7
Once the above settings have been made, then execute linear interpolation
operations by using the following two bits allocated in the Axis Operating Out-
put Memory Area for axis 1 or axis 5.
•
LINEAR INTERPOLATION SETTING
•
LINEAR INTERPOLATION START
Example: Linear Interpolation for 4-axis (Axis 1 to Axis 4) Operation
Note
(1) When executing interpolation operations using a combination of axes 5 to
8, the interpolation axis designation and interpolation position designa-
tion are made for axes 5 to 8 respectively in the Axis 5 Operating Output
Memory Area, in bits 04 to 07 in the corresponding words in the above
diagram.
(2)
Set the acceleration/deceleration curve designation (the S-curve desig-
nation) and the forward/reverse torque designation for each designated
interpolation axis.
