Siemens SINUMERIK 840C User Manual

08.96 2 Defining Parameters
2.3 R11 Empirical value / average value
R11 = 0 Without empirical value, without average value memory
> 0 Number of empirical value memory
The average value memory number is likewise determined via R11 which reduces the time
required for programming.
Special case:
When R11 is defined > 9999, R11 is evaluated as follows:
R11=8765 4321
Empirical value memory number
(max. 0 to 99)
Average value memory number
(max. 1 to 99)
Example: Empirical value memory number 12
R11 = 90012
Average value memory number 9
