(8) The feedrate by
rotary
axis single command is determined in accor¬
dance with
the unit of input
system.
In case of inch input, the feedrate
is as shown below by
parameter
setting.

NOTE
-
1.
If F0 is programmed, it is regarded
as
a
data

(alarm code "370")
2. Do
not
program
F commands with minus numerals, otherwise
correct
