"Major positioning controls" are carried out using the "positioning data" stored in the
Simple Motion module.
The basic controls such as position control and speed control are executed by setting
the required items in this "positioning data", and then starting that positioning data.
The control method for the "major positioning controls" is set in setting item "[Da.2]
Control method" of the positioning data.
Control defined as a "major positioning control" carries out the following types of
control according to the "[Da.2] Control method" setting.
However, the position loop is included for commanding to servo amplifier in the speed
control set in "[Da.2] Control method".
Use the "speed-torque control" (Refer to Section 12.1 "Speed-torque control") to
execute the speed control not including position loop.

Chapter 9 Major Positioning Control
Positioning of the designated 1 axis is carried out from the
start address (current stop position) to the designated
position.
Using the designated 2 axes, linear interpolation control is
carried out from the start address (current stop position) to
the designated position.
Using the designated 3 axes, linear interpolation control is
carried out from the start address (current stop position) to
the designated position.
Using the designated 4 axes, linear interpolation control is
carried out from the start address (current stop position) to
the designated position.
Positioning of the designated 1 axis is carried out for a
designated movement amount from the start address
(current stop position).
(The "[Md.20] Feed current value" is set to "0" at the start.)
Using the designated 2 axes, linear interpolation control is
carried out for a designated movement amount from the
start address (current stop position).
(The "[Md.20] Feed current value" is set to "0" at the start.)
Using the designated 3 axes, linear interpolation control is
carried out for a designated movement amount from the
start address (current stop position).
(The "[Md.20] Feed current value" is set to "0" at the start.)
Using the designated 4 axes, linear interpolation control is
carried out for a designated movement amount from the
start address (current stop position).
(The "[Md.20] Feed current value" is set to "0" at the start.)
Using the designated 2 axes, positioning is carried out in
an arc path to a position designated from the start point
address (current stop position).
