7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
609
NOTE
If there is a series of very short blocks, for each of which the
rate of acceleration/deceleration before interpolation is low,
the a ctual feedrate may not reach the programmed
feedrate.
NOTE
1 If the upper limit for automatic feedrate control is set to 0 in
parameter No. 8465, no feedrate exceeding 0 is permitted,
such that the issue of an F command causes PS alarm 011
(FEED ZERO). To prevent this, specify a value other than
zero in the parameter.
2 If the override is changed while the automatic feedrate
control function is enabled, the calculated cla mp feedrate is
overridden.
WARNING
1 In HPCC mode, axial interlocking (each axis, each direction)
is inhibited (signals G130, G132, G134).
2 In HPCC mode, the external mirror image (DI) signal, a
mirror image determined by setting data, or axial machine
lock must not be changed. Pocket calculator type decimal
point input is disabled in HPCC mode (when bit 0 of
parameter No. 3401 is set to 1).
NOTE
1 A single-- block stop cannot be made at the end of the
G05P10000 block.
2 External deceleration, the F1--digit command, and
automatic corner override are disabled.
3 In HPCC mode, the operation mode cannot be switched to
MDI mode. Also, MDI operation is not permitted.
4 A program including G50 P10000; cannot be resumed.
