The following table shows setting examples when "position-speed switching 
control (forward run: position/speed)" is set in positioning data No. 1 of axis 1. 

 

Setting item 

Setting example 

Setting details 

 Da.1  Operation pattern 

Positioning 

complete 

Set "Positioning complete" assuming the next positioning data will not 
be executed. ("Continuous positioning control" and "Continuous path 
control" cannot be set in "position/speed changeover control".) 

 Da.2  Control system 

Forward run: 

position/speed 

Set position-speed switching control. 

 Da.3  Acceleration time No. 

1 

Designate the value set in "

Pr.25

 Acceleration time 1" as the 

acceleration time at start. 

 Da.4  Deceleration time No. 

0 

Designate the value set in "

Pr.10

 Deceleration time 0" as the 

deceleration time at deceleration. 

 Da.5  

Axis to be 
interpolated 

– 

Setting not required. (Setting value is ignored.) 

 Da.6  

Positioning address/ 
movement amount 

10000.0

µ

m 

Set the movement amount at the time of position control before the 
switching to speed control. (Assuming that the "

Pr.1

 Unit setting" is 

set to "mm".) 

 Da.7  Arc address 

– 

Setting not required. (Setting value is ignored.) 

 Da.8  Command speed 

6000.00mm/min  Set the speed to be controlled. 

 Da.9  Dwell time 

500ms 

Set the time the machine dwells after the positioning stop (pulse 
output stop) by position control to the output of the positioning 
complete signal.  If the machine is stopped by speed control, the 
setting value will be ignored. 

Ax
