9   MAJOR POSITIONING CONTROL 
 
9.1 Outline of major positioning controls 
"Major positioning controls" are carried out using the "positioning data" stored in the 
QD75MH.  
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.

Details 
1-axis linear 
control 
ABS Linear 1 
INC Linear 1 
Positioning of a designated 1 axis is carried out from the 
start address (current stop position) to the designated 
position. 
2-axis linear 
interpolation 
control   
ABS Linear 2 
INC Linear 2 
Using a designated 2 axes, linear interpolation control is 
carried out from the start address (current stop position) to 
the designated position. 
3-axis linear 
interpolation 
control   
ABS Linear 3 
INC Linear 3 
Using a designated 3 axes, linear interpolation control is 
carried out from the start address (current stop position) to 
the designated position. 
Linear control 
4-axis linear 
interpolation 
control   
ABS Linear 4 
INC Linear 4 
Using a designated 4 axes, linear interpolation control is 
carried out from the start address (current stop position) to 
the designated position. 
1-axis fixed-
feed control 
Fixed-feed 1 
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.) 
2-axis fixed-
feed control   
Fixed-feed 2 
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.) 
3-axis fixed-
feed control   
Fixed-feed 3 
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.) 
Fixed-feed 
control 
4-axis fixed-
feed control   
Fixed-feed 4 
Using a designated 4 axes, linear interpolation control is 
carried out from the start address (current stop position). 
(The "

The axis in which the interpolation control system is set is 
regarded as the reference axis. Positioning is carried out in 
an arc path to a designated position, while controlling the 
other axis (interpolation axis) to match the positioning data 
set in the reference axis. 
1-axis speed 
control 
Forward run speed 1 
Reverse run speed 1 
The speed control of the designated 1 axis is carried out. 
2-axis speed 
control   
Forward run speed 2 
Reverse run speed 2 
The speed control of the designated 2 axes is carried out. 
3-axis speed 
control   
Forward run speed 3 
Reverse run speed 3 
The speed control of the designated 3 axes is carried out. 
Speed control   
4-axis speed 
control   
Forward run speed 4 
Reverse run speed 4 
The speed control of the 4 axes is carried out.
