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-feed 3

Set 3-axis fixed-feed 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 will be
ignored).

When axis 1 is used as a reference axis, the
interpolation axes are axes 2 and 3.

Da.6

Positioning address/
movement amount

10000.0

µ

m

5000.0

µ

m

6000.0

µ

m

Set the positioning address. (Assuming "mm"

is set in "

Pr.1

Unit setting".)

Da.7 Arc address

Setting not required (setting value will be
ignored).

Da.8 Command speed

6000.00
mm/min

Set the speed during movement.

Da.9 Dwell time

500ms

Set the time the machine dwells after the
positioning stop (pulse output stop) to the
output of the positioning complete signal.

A

Da.10 M code

Set this when other sub 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.

POINTS

(1) When the "reference axis speed" is set during 3-axis fixed-feed control, set so the major axis side

becomes the reference axis. If the minor axis side is set as the reference axis, the major axis side

speed may exceed the " Pr.8 Speed limit value".

(2)Refer to Section 9.1.6 "Interpolation control" for the reference axis and interpolation axis

combinations.
