Multiple Measurement At The Same Location: _Nmsp; Weighting Factor For Mean Value Calculation - Siemens SINUMERIK 840D sl Programming Manual

The default setting provides 20 values each (array index _EV, _MV: 0...19).
Parameter
Values of _EVNUM
=0
>0to 9999
>9999
The array index for _EV and _MV is formed from the value in _EVNUM.
Example
_EVNUM
_EVNUM

Multiple measurement at the same location: _NMSP

Parameter
Parameter _NMSP can be used to determine the number of measurements at the same
location.
The measured values or distances-to-go Si (i=1...n) are averaged.
That results, for example, in distance-to-go D:
D = (S
n: Number of measurements
2.3.16 Weighting factor for mean value calculation: _K
Parameter
The parameter for weighting factor _K can be applied to allow different weighting to be given
to an individual measurement.
Note
A detailed description is given in the chapter "General section, measuring strategy and
compensation value definition".

Empirical value memory number = mean value memory number
The top 4 digits of _EVNUM are interpreted as the mean value memory
number, the lower 4 digits as the empirical value memory number.
