Note
The following overrides are not effective in G331 and G332:
● Programmable path feedrate override OVR
● Rapid traverse override
Inhibiting stop events for G331/G332
During tapping, a stop can be prevented if the block contains a path motion or a G4 as follows:
MD11550 $MN_STOP_MODE_MASK, bit 0 = 0
The stop which was activated previously is possible again after G331/G332 has been executed.

Feedrate for tapping with compensating chuck (G63)

Function
G63 is a subfunction for tapping threads using a tap with compensating chuck. An encoder
(position encoder) is not required.
Speed S, feedrate F, thread pitch
With G63, a speed S must be programmed for the spindle and a feedrate F for the infeed axis
(axis for thread length).
The feedrate F must be calculated by the programmer on the basis of the speed S and the
thread pitch.
Feedrate F [mm/min] = speed S [rev/min] * pitch [mm/rev]

Value Meaning
0 The override influences the spindle speed (initial setting).
Depending on the setting in the machine data:
MD12080 $MN_OVR_REFERENCE_IS_PROG_FEED
the override is related either to the programmed spindle speed or to the configured
spindle speed limitation.
1 The override influences the path feedrate
Depending on the setting in machine data: MD12082 $MN_OVR_REFER‐
ENCE_IS_MIN_FEED
the override is related either to the programmed path feedrate or to the configured
path feedrate limitation.
