■ 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.
Note
If executing circular interpolation start, 2 axes will operate at the same time. Need user to pay attention.
(1) Auxiliary operations may be used are as follows.
▪ Speed override, Dec. stop, Emergent stop, Skip operation.
(2) The commands may not be used in circular interpolating operation are as follows.
▪ Position/Speed switching control, Position override, Continuous operation
(3) The parameter items operating by standards of each axis are as follows.
▪ Amount of backlash revision in extended parameter items, Software high limit, Software low limit
