7 MOTION PROGRAMS FOR POSITIONING CONTROL
Constant-speed control is
executed in this area.
(8) If the G02 or G03 command is executed during the G01 command (Constant-
speed positioning), a deceleration stop is not made.
[Example] G01 X100. Y100. Z100. ;
G02 X0. Y0. I0. J50. F500. ;
G03 X0. Y0. I0. J50. F500. ;
G01 X100. ;
(9) Acceleration/deceleration processing of G01 command
G91 G01 X100. Y100. F100. ; Constant-speed positioning of X, Y..... Block 1
Y100. ; Constant-speed positioning of Y.......... Block 2
X100. ; Constant-speed positioning of X..........Block 3
When the above program is executed, the acceleration/deceleration processing of
the X and Y-axis is shown below.

(Note) : 1) Both the acceleration and deceleration times are the acceleration time
of the parameter block.
2) When a M-code is commanded, G00 executes the acceleration/
deceleration in the same way as G01 at the acceleration time of the
parameter block.
[Related Parameters]
Speed limit value : The maximum feed rate of each axis is set.
(Refer to Section 6.4.1 for the speed limit value of the parameter
block.)
