9 MAJOR POSITIONING CONTROL

(5) An error "No command speed" (error code: 503) occurs if a current speed (-1)

is set in "

Da.8

Command speed".

(6) The software stroke limit check is not carried out when the control unit is set to

"degree".

Positioning data setting examples

[Setting examples when the reference axis and interpolation axis are designated
as axes 1 and 2, respectively.]
The following table shows the setting examples when "2-axis speed control
(forward run: speed 2)" is set in the positioning data No. 1 of axis 1 (reference
axis).

Setting details

Da.1 Operation pattern

Positioning

complete

–

Setting other than "Positioning complete" is not possible in
speed control.

Da.2 Control system

Forward run

speed 2

–

Set 2-axis speed control.

Da.3

Acceleration time
No.

–

Designate the value set in " Pr.25 Acceleration time 1" as
the acceleration time at start.

Da.4

Deceleration time
No.

–

Designate the value set in " Pr.10 Deceleration time 0" as
the deceleration time at deceleration.

Da.5

Axis to be
interpolated

–

Set the axis to be interpolated (partner axis).

If the self-axis is set, an error will occur.

Da.6

Positioning address/
movement amount

–

Setting not required (setting value will be ignored).

Da.7 Arc address

–

Setting not required (setting value will be ignored).

Da.8 Command speed

6000.00
mm/min

3000.00
mm/min

Set the speed to be commanded.

Da.9 Dwell time

–

Setting not required (setting value will be ignored).

is 1 Positioning data N

. 1

Da.10 M code

–

Set this when other sub operation commands are issued in

combination with the No. 1 positioning data. (" Pr.18 M

code ON signal output timing" setting only possible in the
WITH mode.)

Refer to Section 5.3 "List of positioning data" for information on the setting details.
