The MEASURE( ) function calculates frame $AC_MEAS_FRAME according to the specified
frame.
In the case of values
0 to 1065, the calculation is performed using the active frame.
2000 to 3065, the calculation is performed with reference to the selected frame in data
management. The frame selection in data management is not supported for measurement
types 14 and 15. A frame does not have to be active in order to select it in data
management. In this case, the calculation is performed as if the frame were active in the
chain.
The measuring point is transformed in the selected system and the selected frame is
determined using the entire frame including the selected frame. Preset actual value memory
is active only after compensation and activation of the frame.
In the case of values with active G500 active (1010..1025, 1050..1065, 3010..3025,
3050..3065), the target frame is calculated so that G500 must be active after the frame is
selected so that the setpoint position can be calculated.
Conversion into another coordinate system
If a position is to be converted to a position in another coordinate system, the following
variables can be used to specify the composition of the desired frame chain:

INT $AC_MEAS_NCBFR
INT $AC_MEAS_CHBFR
INT $AC_MEAS_UIFR
INT $AC_MEAS_PFRAME
