Performs two-axis circular interpolation at the specified interpolation speed.
The current position is the default coordinate data in the specified circular plane.
If the interpolation speed isn't specified, the interpolation will be performed at the
last speed used in a G01, G02, or G03 function. An error will occur if the inter-
polation speed isn't specified and a G01, G02, or G03 function hasn't been
executed before.
When specifying the circle's center coordinate, specify the relative distance from
the current position (the circle's starting point) and specify one or two axes. An
error will occur if there is no specification.
When specifying the radius, an arc smaller than a semicircle will be drawn with
positive values and an arc greater than a semicircle will be drawn with negative
values. Either a negative or positive value can be specified for a semicircle.
When specifying a complete circle (360_), the system will operate when either of
the following conditions is met in the arc center coordinate specifications.
• When the axis movement command and current position are the same
• When the axis movement command is left out
A complete circle can't be drawn by the radius specification.
The G02 and G03 functions use the interpolation acceleration time, interpolation
deceleration time, and override value of the X axis.
The override value can be specified from the Teaching Box or PC data area inter-
face.
The override is referred to only once at the start of G02 and G03. The feed rate
cannot be changed during operation.
When circular interpolation is performed in pass mode and an M code from 0
through 499 or an optional number is specified, the interpolation will be per-
formed in stop mode, not pass mode.
