WARNING
No override can be used for some commands.
After specifying G95 (in the feed per revolution mode), the amount of
feed of the tool per position coder revolution is to be directly specified by
setting a number after F. G95 is a modal code. Once a G95 is specified,
it is valid until G94 (feed per minute) is specified.
An override from 0% to 254% (in 1% steps) can be applied to feed per
revolution with the switch on the machine operator’s panel. For detailed
information, see the appropriate manual of the machine tool builder.

When the speed of the position coder is low, feedrate
fluctuation may occur. The slower the spindle rotates, the
more frequently feedrate fluctuation occurs.
