8 Select the Program Run, Full Sequence operating
mode.
8 Shift the soft-key row.
8 To activate the adaptive feed control: Set the soft key
to ON, and the TNC displays the AFC symbol in the
position display (see “Status Displays” on page 51).
8 To deactivate the adaptive feed control: Set the soft
key to OFF.
The adaptive feed control remains active until you
deactivate it by soft key.
If the adaptive feed control is active in the control mode,
the TNC internally sets the spindle override to 100%. Then
you can no longer change the spindle speed.
If the adaptive feed control is active in the control mode,
the TNC takes over the feed rate override function:
„ If you increase the feed rate override, it has no influence
on the control.
„ If you decrease the feed rate override by more than 10%
with respect to the maximum setting, the TNC switches
the adaptive feed control off. In this case the TNC
displays a window to inform you.
The adaptive feed control is not active in NC blocks
containing G0.
Mid-program startup is allowed during active feed rate
control and the TNC takes the cut number of the startup
point into account.
In the additional status display, the TNC displays various
information when the adaptive feed control is active (see
“Adaptive Feed Control (AFC tab, software option)” on
page 59). In addition, the TNC shows the symbol
in the
position display.
