C and CP enable you to program a complete circle in one block.
With Cartesian coordinates
With polar coordinates

„
Define the pole CC before programming polar coordinates.
„ You can define the pole CC only in Cartesian coordinates.
„
The pole CC remains in effect until you define a new pole
CC.
„ The arc end point can be defined only with the polar
coordinate angle (PA)!
