cleared upon a reset or after the power is turned off and then
on again, the acceleration/deceleration reference speed
specified for parameter No. 7066 (AICC or AI nanoCC) or
No.19520 (AI-HPCC or AI-nanoHPCC) will be used. (Method
(2), described later)
If the acceleration/deceleration reference speed specified for
the parameter is 0, the feedrate assumed at the start of
cutting will be assumed the acceleration/deceleration
reference speed. (Method (3), described later)
(Program example)
G05.1 Q1 F5000 ; ・・・Sets the reference speed to 5000 mm/min.
The F command used in a G05.1 block is used to specify the
acceleration/deceleration reference speed, and is also used as a
normal F command.
Even if the feedrate is changed during the execution of the
machining program, the acceleration/deceleration reference
speed specified with the above command remains in effect. If
this occurs, the machining time may become longer because
machining is performed at the feedrate different from the
acceleration/deceleration reference speed.
For this reason, the acceleration/deceleration reference speed
to be specified with the above command should be as close as
possible to the actual machining speed.
NOTE
The G05.1Q1Fxxxx, G05P10000Fxxxx command must be issued in
feed per minute (G94) mode.
If this command is issued in another mode, the speed specified with
this command will be generated the alarm( PS5111).
(2) Setting the speed on the Parameter
the acceleration/deceleration reference speed is set in
parameter No. 7066( AICC or AI nanoCC) or No.19520( AI-
HPCC or AI-nanoHPCC).
Because these parameters must be set in input unit, when the
input unit is changed, these parameters must be changed.
This method is used if the G05.1Q1 block or G05 P10000 block
does not have an F command.
