Linear Interpolation
Section 9-7
Note When executing linear interpolation operations, the Acceleration Constant
Switching Speed (Pn80C) and the Deceleration Constant Switching Speed
(Pn80F) in the Servo Parameter Area must each be set to 0. Linear interpola-
tion operations cannot be properly executed if any number other than 0 is set.
Linear interpolation operations can be executed for this PCU only with a
1-step acceleration/deceleration curve.

Option Command
Value 1 a+10 --- Linear interpolation acceleration time
Unit: ms
Command range: 0 to 65535 (0000 hex to FFFF hex)
a+11 --- Not used (Set value disabled.)

Interpolation Axis
Designation a+21 00 to 03
(Axis 1 to
Axis 4)
04 to 07
(Axis 5 to
Axis 8)
0: Not designated as interpolation axis.
1: Designated as interpolation axis.
Designates axes for executing linear interpolation.
Combinations of axes 1 to 4 are designated in bits 00 to 03 (Axis 1 Operat-
ing Output Memory Area), and combinations of axes 5 to 8 are designated
in bits 04 to 07 (Axis 5 Operating Output Memory Area).
Bits 00 to 03, and bits 04 to 07, correspond respectively to axes 1 to 4 and
axes 5 to 8.
Interpolation Posi-
tion Designation a+22 00 to 03
(Axis 1 to
Axis 4)
04 to 07
(Axis 5 to
Axis 8)
0: Execute interpolation operations using absolute position.
1: Execute interpolation operations using relative position.
Specifies, for axes designated by the interpolation axis designation, whether
positioning in interpolation operations is to be executed using absolute or
relative positions.
Positions for axes 1 to 4 are designated in bits 00 to 03 (Axis 1 Operating
Output Memory Area), and positions for axes 5 to 8 are designated in bits
04 to 07 (Axis 5 Operating Output Memory Area). These bits correspond
respectively to axes 1 to 4 and axes 5 to 8.
