3-Axis Linear Interpolation Control - Mitsubishi Electric QD75P1N User Manual

9 MAJOR POSITIONING CONTROL

9.2.4 3-axis linear interpolation control

In "3-axis linear interpolation control" (" Da.2 Control system" = ABS linear 3, INC
linear 3), three motors are used to carry out position control in a linear path while
carrying out interpolation for the axis directions set in each axis.
(Refer to Section 9.1.6 "Interpolation control" for details on interpolation control.)

Operation chart
In absolute system 3-axis linear interpolation control, 3 axes are used. Linear
interpolation positioning is carried out from the current stop position (start point
address) to the address (end point address) set in " Da.6 Positioning
address/movement amount".
