Explanation The arithmetic functions can also be programmed in synchronized actions. Arithmetic functions are
calculated and evaluated in the main run. Synchronized action parameter $AC_PARAM[n] can also be
used for calculations and as buffer memory.

Explanation
The function provides information
about the assignment of the tool
lengths L1, L2, L3 of the active
tools to abscissa, ordinate,
applicate. The assignment to the
geometry axes is affected by
frames and the active plane
(G17 - 19). Details: See Function
Manual Basic Functions; (W1)

Checks whether the variable
value lies within the defined
min/max value range
