"Major positioning controls" are carried out using the "positioning data" stored in the
QD75.
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 system for the "major positioning controls" is set in setting item
" Da.2 Control system" of the positioning data.
Control defined as a "major positioning control" carries out the following types of
control according to the " Da.2 Control system" setting.

Positioning of a designated 1 axis is carried out from the
start address (current stop position) to the designated
position.
Using a designated 2 axes, linear interpolation control is
carried out from the start address (current stop position) to
the designated position.
Using a designated 3 axes, linear interpolation control is
carried out from the start address (current stop position) to
the designated position.
Using a designated 4 axes, linear interpolation control is
carried out from the start address (current stop position) to
the designated position.
Positioning of a designated 1 axis is carried out from the
start address (current stop position).
(The " Md.20 Current feed value" is set to "0" at the
start.)
Using a designated 2 axes, linear interpolation control is
carried out from the start address (current stop position).
(The " Md.20 Current feed value" is set to "0" at the
start.)
Using a designated 3 axes, linear interpolation control is
carried out from the start address (current stop position).
(The " Md.20 Current feed value" is set to "0" at the
start.)
Using a designated 4 axes, linear interpolation control is
carried out from the start address (current stop position).
(The " Md.20 Current feed value" is set to "0" at the
start.)
Positioning is carried out in an arc path to a position
designated from the start point address (current stop
position), using the designated 2 axes.
Circular interpolation control is carried out with two of the
three axes. The other axis tracks the movement of the
circular interpolation control to carry out the positioning in
helical or tangential/normal control.
