Output values

Calculation results
If a setpoint position has been specified, the resulting frame is entered in result frame
$AC_MEAS_FRAME. This frame can be read and written in the part program. The result
frame is calculated according to the selected frame.
If no frame has been selected, the result frame determines the final translation and rotation
in the WCS. This frame can be entered in the selected frame using the PI service
_N_SETUDT and parameter type no. 7. Once it has been entered, the result frame is
deleted.
