Title

No.
Feed with a specified feedrate (feed per revolution)
A movement is made at a feedrate specified in F on an axis from the current position
to the point separated by a specified value.
Format
// ZDO ;
G95 G91 G01 IP ___ F___ ;
ZEND ;
G95 :G code for feed per revolution
G91 :G code for incremental command
IP __:Travel distance
F__ :Feedrate command (mm/rev or inch/rev)
NOTE
1. Only one axis can be specified in one block.
2. The absolute command (G90) cannot be specified.
3. The block overlap function cannot be used.
4. Be sure to set the parameters below to 0. If a value other than 0 is
set, the feedrate specification range changes, depending on the set
parameter.
FR1 (bit 6 of parameter No. 8002)
FR2 (bit 7 of parameter No. 8006)
5. The feedrate is clamped to the maximum cutting feedrate set in
parameter No. 8022. (Parameter No. 1430 for an NC statement is
not valid for this command.)
6. To use feed per revolution, a position coder is required at all times.
(Bit 0 (NPC) of parameter No. 1402 is not applicable to this command.)
7. No time is added to the cumulative cutting time.
8. Even if this command is executed, the cutting in-progress signal is not
output.
9. The operation between blocks for feed with a specified feedrate is
performed in the cutting mode at all times.
10. For this command, the feedrate arrival signal SAR (G029.4) cannot be
used.
