(b) Restrictions
■ Circular interpolation with designating radius method may not draw an exact circle that the starting position and ending
position are same. If user wants to draw an exact circle, use circular interpolation with center point method.
■ In the cases below, error would arise and circular interpolation may not be executed.
▪
「
Sub-axis setting
」
error (error code: 279)
- Value of
「
Sub-axis setting
」
is “Axis-undecided”
-
「
Sub axis setting
」
of main axis operating data is the same as main axis no.
-
「
Sub axis setting
」
of main axis operating data exceeds the settable axis no. of module now using.
▪ Control unit of main or sub axis is set as “degree”. (error code : 282(main), 283(sub))
▪ Starting position and goal position are same (error code: 285)
▪ Radius value of circular interpolation of main-axis operating data is smaller than half of the length from starting position
to goal position
- Radius < (R x 0.8) : Error (error code: 270)
- (R x 0.8) <= Radius < R
: Execute circular interpolation after reset the radius to R. In other words, execute circular interpolation by setting the
center of the line from starting position to goal position as center point.

When executing circular interpolation with absolute coordinates,
set
「

1000 -
Use connecting speed designation method for circular
interpolation. Set connecting speed on main-axis
Acc. no. No.1 - Set no. of acc. time to use in acceleration (no1~4)
Dec. no. No.2 - Set no. of dec. time to use in deceleration (no1~4)
M code 0 -
Set it when executing another auxiliary operation synchronizing
with circular interpolation
Dwell time 500 - Set dwell time for outputting positioning complete
Sub-axis
setting
Axis2 -
Set an axis to use as sub-axis among the axis available on main-
axis operating data.

The No. of
Turns
- - Set the no. of turns of arc for making a circle bigger than 360°
Helical Not use -
When using circular interpolation, set it to
「
Not use
」
-
*1
: It means that no need to be set. Whatever value it is, it dose not affect circular interpolation.
