Remark
Caution is needed, because 2 axes work simultaneously in the circular interpolation operation.
(1) Available auxiliary operations are as follows ;
▪ Speed override, Deceleration stop, Emergency stop, Skip operation
(2) Unavailable commands during circular interpolation operation are as follows ;
▪ Position/Speed switching control, Position override, Continuous operation
(3) The parameter items which are operated by the set value of each axis are as follows ;
▪ Software upper limit, software lower limit among extended parameter.

interpolation
Absolute, single-
axis position
control
When circular interpolation control is executed
by
the absolute coordinate method,
set
「
Absolute, circular interpolation
」
on the
main axis. Set the coordinate of sub-axis as
“Absolute” too.
Operation method Single, End -
*1
Set operation method for circular interpolation.
Target position
[pls]
10000 0
Set the target position for positioning on the
main, sub axes
Operation speed
[pls/s]
1000 -
Circular interpolation uses the method of
designating composition speed. Set the
composition speed at the main-axis
Acceleration No. No.1 -
Set Acc. No. for acceleration
(no.1 ~ no.4)
Deceleration No. No.2 -
Set Dec. No. for deceleration.
(no.1 ~ no.4)
M code 0 -
When you need to execute auxiliary work based
on the interpolation operation, set the M code
Dwell time 500 -
Set dwell time(ms) needed to output the
positioning completion signal
Sub-axis setting Axis 2 -
Set an axis to be used as sub-axis among
settable axis in operating data of main-axis
Circular
interpolation
Auxiliary point
5000 5000
In case of middle point specified circular
interpolation, set the position of the middle
point where circular arc passes
Circular
interpolation mode
Middle point -
In case of middle point specified circular
interpolation, select
「
middle point
」
on the
main axis.
Circular
interpolation
turns
0 -
When user want to draw circle of over 360
degree, set the number of turns of circular arc.
Helical interpolation
Don‟t use
-
In case of circular interpolation, select
「
Do
not use
」
on the main axis.
