Fixed Feedrates F0 To F9 - Siemens Sinumerik 840D sl Programming Manual

Figure 1-3
Note
If "F0" is programmed and the function "Fixed feedrate" is not active, then the Alarm 14800
"Programmed path velocity less than or equal to zero" is output.

Fixed feedrates F0 to F9

Activate feed values
Ten different feed values pre-set via setting data can be activated with F0 to F9. To activate
the rapid traverse rate with F0, the corresponding speed must be entered in the setting data
42160 $SC_EXTERN_FIXED_FEEDRATE_F1_F9[0].
The feed values for F0 to F9 are entered in the setting data as real values. An evaluation of
the input values is not undertaken.
The function is activated via the machine data 22920
$MC_EXTERN_FIXED_FEEDRATE_F1_ON. If the machine data is set to FALSE, F1 - F9 is
interpreted as normal feed programming, e.g. F2 = 2 mm/min, F0=0 mm/min.
If the machine data = TRUE, the feed values for F0 - F9 are fetched from the setting data
42160 $SC_EXTERN_FIXED_FEEDRATE_F1_F9[ ]. If the value 0 exists in one of the
setting data, then the corresponding address extension of feed 0 is activated during the
programming.
