F1-digit feed

It is possible to select a feedrate by specifying a 1-digit numeral (1 to 9) following
address F. With this manner of designation of an F command, the feedrate preset
for the specified numeral is selected.
The F1--Digit Feed function needs to be enabled by MD setting as follows:
$MC_FIXED_FEEDRATE_F1_F9_ACTIV = TRUE: F1--Digit Feed enable
$MC_FIXED_FEEDRATE_F1_F9_ACTIV = FALSE: F1--Digit Feed disable
With the above mentioned MD set to FALSE, F1 to F9 in a machining program is
interpreted as standard feed (F) programming, i.e. F2 = 2 mm/min. With the above
mentioned MD set to TRUE, the feedrate to be selected in response to the desi-
gnation of F1 to F9 should be set for the setting data indicated in Table 1-3.
Feedrate 0 is activated if the corresponding value of the setting data is 0.
