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.
9.1

Overview of the Major Positioning Controls

Major positioning controls are implemented using positioning data stored in the positioning module.
The positioning controls, such as the position control and speed control, are implemented 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.

Description
Implements positioning control from the start point address (current stop
position) to the specified position using the specified one axis.
Implements linear interpolation control from the start point address
(current stop position) to the specified position using the specified two
axes.
Implements 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.)
Implements 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.)
Implements positioning control in an arc path from the start point address
(current stop position) to the specified position using the specified two
axes.
Performs the speed control of the specified one axis.
Performs the speed control of the specified two axes.
Implement speed control, and then position control (Positioning with the
specified address or movement amount) immediately after that by turning
on the speed-position switching signal.
Performs the position control, and then speed control immediately after
that by turning on Position-speed switching signal.
