9 MAIN POSITIONING CONTROL
Restrictions
(1) An error "Continuous path control not possible" (error code: 516) will occur and
the operation cannot start if "continuous path control" is set in " Da.1
Operation pattern". ("Continuous path control" cannot be set in fixed-
dimension feed control.)
(2) "Fixed-dimension feed" cannot be set in " Da.2 Control method" in the
positioning data when "continuous path control" has been set in " Da.1
Operation pattern" of the immediately prior positioning data. (For example, if
the operation pattern of positioning data No. 1 is "continuous path control",
fixed-dimension feed control cannot be set in positioning data No. 2.) An error
"Continuous path control not possible" (error code: 516) will occur and the
machine will carry out a deceleration stop if this type of setting is carried out.
Positioning data setting example
The following table shows setting examples when "1-axis fixed-dimension feed
control (fixed-dimension feed 1)" 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.
Da.2
Control method
Fixed-dimension
feed 1
Set 1-axis fixed-dimension feed control.
Da.3
Acceleration time
No.
1
Designate the value set in " Pr.26 Acceleration time 1" as the
acceleration time at start.
Da.4
Deceleration time
No.
0
Designate the value set in " Pr.9 Deceleration time 0" as the
deceleration time at deceleration.
Da.5

movement amount
80000. 0
µ
m
Set the positioning address. (Assuming "mm" is set in " Pr.1 Unit
setting".)
Da.6
Arc address
– Setting not required (setting value will be ignored).
Da.7
Command speed
6000.00mm/min Set the speed during movement to the positioning address.
Da.8
Dwell time
500ms
Set the time the machine dwells after the positioning stop (pulse output
stop) to the output of the positioning complete signal.

Da.9
M code
10
Set this when other auxiliary operation commands are issued in
combination with the No. 1 positioning data.
* Refer to section "5.3 List of positioning data" for information on the setting details.
