Inputs/Outputs

Name Function
Specify the
AxisGroup
axis group.
*Note:
DMC_AXIS_GROUP_REF (FB): All function blocks for an axis group contain this variable, which works as the starting program
for function blocks.
Function

The instruction supports the relative helical interpolation of maximum three axes, where the three axes can

simultaneously start, stop as well as reach the specified relative target position.
The instruction can be used to specify the circle drawing on the plane parallel to XY / YZ / ZX and set the

height of the helix on Z / X / Y axis.
If the start point and end point for circular interpolation are set to the same point, use the center point mode

(CircMode = Center) for the interpolation.
At least two axes are needed for circular interpolation. An error will occur if there is a travel distance for an

axis which is not set.
When the start point and end point for circular interpolation are set to the same point, the instruction will

perform the rotation for one complete circle.
The function of CoordSystem needs to be supported by DL_MotionControl library V1.1.0.0 or above.

CircPlane added ARBITRARY_plane in DL_MotionControl library V1.2.0.0 or later.

ARBITRARY_plane can draw ellipses in space.

Use the following parameters to draw the ellipse.
