Feed (V1)
24.1 Path feedrate F
Maximum tool path velocity
The maximum path velocity is obtained from the maximum velocities of the relevant axes
(MD32000 MAX_AX_VELO) and their proportion of the path. The maximum velocity of an
axis stored in the machine data cannot be exceeded.
CFC feedrate override for circles
When machining circular contours using milling tools and the active tool radius
compensation (G41/G42), the feedrate at the milling cutter center must be adjusted if the
programmed F value is intended to be active at the circular contour. If the CFC feedrate
override is active, inside and outside circle machining is detected automatically.
The feedrate override can be switched-off using CFTCP.

Interface signals
If the revolutional feedrate is active, IS "Revolutional feedrate" (V3300 0001.2) is set.
If the G96/G332 function is active, the IS "Constant cutting rate active" (V390x 2002.0) is set
for the spindle.
Alarms
● If no F word is programmed at G1, G2, G3, ..., alarm 10860 is issued. An axis movement
● If F0 is programmed, alarm 14800 is issued.
● If G95 is active and the spindle is stationary, an axis movement is not possible. No alarm
