ROTATION (Cycle 10)
The TNC can rotate the coordinate system about the active datum in
the working plane within a program.
Effect
The ROTATION cycle becomes effective as soon as it is defined in the
program. It is also effective in the Positioning with MDI mode of
operation. The active rotation angle is shown in the additional status
display.
Reference axis for the rotation angle:
„ X/Y plane X axis
„ Y/Z plane Y axis
„ Z/X plane Z axis
 Rotation: Enter the rotation angle in degrees (°). Input
range: –360° to +360° (absolute or incremental).
Cancellation
Program the ROTATION cycle once again with a rotation angle of 0°.

Before programming, note the following
An active radius compensation is canceled by defining
Cycle 10 and must therefore be reprogrammed, if
necessary.
After defining Cycle 10, you must move both axes of the
working plane to activate rotation for all axes.
