Usually the machine origin is placed in the rotation axis A. If necessary, it can be shifted by the parameters HD7..HD9. Differing zero positions of the rotary axes A and C can be adjusted by the parameters HD10 and HD11 in a way, that the internal kinematic model matches to the real machine kinematic. In the same way also differing rotation directions of the A and C axes can be adjusted by the parameters HD12 and HD13. Then, in general in the axes parameters also the signs of commanded and actual values have to be adjusted correspondingly.
