7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
915
Set the acceleration change time for bell–shaped acceleration/
deceleration before interpolation (time required for changing from the
constant feedrate status (A) to the constant acceleration/deceleration
status (C) in which the acceleration calculated based on the acceleration
set in parameter No. 19510 is used; time (B) in the following figure).
(A) (B) (C) (A) (B) (C) (B) (A)
Tangential feedrate
The optimum gradient is
automatically calculated
using the setting of param-
eter No. 19510.
The time is set in parameter No. 8416.

ZAG The function of decelerating according to the cutting load (deceleration
according to the angle at which the tool moves downward along the
Z–axis) in AI high–precision contour control is:
0 : Not performed.
1 : Performed.
When setting this parameter to 1, always set parameters Nos. 8456, 8457,
and 8458.
NOF The F commands in AI high–precision contour control are:
0 : Not ignored.
1 : Ignored.
When this parameter is set to 1, the maximum feedrate set in parameter
No. 8465 is assumed to be specified.
