6 MOTION PROGRAMS FOR POSITIONING CONTROL
(5) When this command is executed continuously, the acceleration or deceleration is
not made at the start or end point of a block because the status is not the exact
stop check mode.
(6) When the circular arc central coordinates and radius are specified simultaneously
for G03 (CCW), the radius-specified circular interpolation has priority.
(7) The positioning data can be set by direct setting (numerical value) or indirect
setting (variable : #
).
[Related Parameters]
Speed limit value : The maximum feed rate of each axis is set.
(Refer to Section 5.3.1 for the speed limit value of the
parameter block.)
Circular interpolation arc error : The allowable error range for circular interpolation is
set.
(Refer to Section 5.3.3 for the allowable error range for
circular interpolation of the parameter block.)
