V1: Feedrates
17.3 Feedrate FA for positioning axes
Note
Maximum axis velocity
The maximum axis velocity is not exceeded:
MD32000 $MA_MAX_AX_VELO (maximum axis velocity)
F function output to the NC/PLC interface
Output of the F functions to the NC/PLC interface is not recommended. Activating the
output of F functions to the NC/PLC interface can cause a drop in velocity in continuous-
path mode. The output of F functions to the NC/PLC interface can be suppressed:
MD22240 $MC_AUXFU_F_SYNC_TYPE (output time of the F functions)
For a detailed description please refer to:

RESET response
After end of program or NC-RESET, the feedrate value takes effect depending on machine data:
MD22410 $MC_F_VALUES_ACTIVE_AFTER_RESET = <value>
Value Meaning
0 After NC RESET the default values are effective.
1 After NC RESET the last FA values to be programmed are effective.
