Feed rate F
The feed rate is the speed in mm/min (or inch/min) with which the tool
center moves.
Input range:
F = 0 to 99 999 mm/min (3937 inch/min)

Rapid traverse
If you wish to program rapid traverse, press ENT for FMAX. If you know
the maximum traverse speed, you can also program it directly. FMAX is
effective only for the block in which it is programmed.
Duration of feed rate F
A feed rate that is entered as a numerical value remains in effect until the
control executes a block in which another feed rate has been pro-
grammed.
If the new feed rate is FMAX (rapid traverse), the feed rate will return to
the last numerically entered feed rate as soon as the FMAX block is
executed.
Changing the feed rate F
You can vary the tool feed rate by turning the knob for feed rate override
on the operating panel (see page 2-6).
