MAJOR POSITIONING CONTROL
This chapter describes the details and usage of the major positioning control (the control function using Positioning data).
As the major positioning control, Position control (positioning to the specified position using address information), Speed
control (controlling a rotating body at a fixed speed), Speed-position switching control (switching the control type from Speed
control to Position control), Position-speed switching control (switching the control type from Position control to Speed
control), and others are provided.
Configure the settings required for each control.
3.1
Overview of the Major Positioning Controls
Major positioning controls are performed using Positioning data stored in the RD75.
The positioning controls, such as the position control and speed control, are executed by setting the required items in this
Positioning data and starting that positioning data.
The control method of Major positioning control is set in [Da.2] Control method of the positioning data.
The control defined as Major positioning control performs the following control depending on the setting in [Da.2] Control
method.

Position
control
*1
Linear control 1-axis linear control ABS linear 1
INC linear 1 Performs the positioning control from the start point address
(current stop position) to the specified position using the
specified one axis.
2-axis linear
interpolation control
*1
ABS linear 2
INC linear 2 Performs the linear interpolation control from the start point
address (current stop position) to the specified position using
the specified two axes.
3-axis linear
interpolation control
*1
ABS linear 3
INC linear 3 Performs the linear interpolation control from the start point
address (current stop position) to the specified position using
the specified three axes.
4-axis linear
interpolation control
*1
ABS linear 4
INC linear 4 Performs the linear interpolation control from the start point
address (current stop position) to the specified position using
four axes.
Fixed-feed control 1-axis fixed-feed control Fixed-feed 1 Performs the positioning control from the start point address
(current stop position) using the specified one axis.
([Md.20] Current feed value is set to 0 at the start.)
2-axis fixed-feed
control
*1
Fixed-feed 2 Performs the linear interpolation control from the start point
address (current stop position) using the specified two axes.
([Md.20] Current feed value is set to 0 at the start.)
3-axis fixed-feed
control
*1
Fixed-feed 3 Performs the linear interpolation control from the start point
address (current stop position) using the specified three axes.
([Md.20] Current feed value is set to 0 at the start.)
4-axis fixed-feed
control
*1
Fixed-feed 4 Performs the linear interpolation control from the start point
address (current stop position) using four axes.
([Md.20] Current feed value is set to 0 at the start.)
2-axis circular
interpolation control
*1
Sub point specification ABS circular sub
INC circular sub Performs the positioning control in an arc path from the start
point address (current stop position) to the specified position
using the specified two axes.
Center point
specification ABS circular right
ABS circular left
INC circular right
INC circular left
3-axis helical
interpolation control
*1
Sub point specification ABS helical sub
INC helical sub Performs the circular interpolation control using two axes of the
three axes. The remaining axis is used for the positioning of the
helical, tangent line, or normal line control to follow the circular
interpolation control.
