7 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 G02 (CW), the central coordinates-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 6.4.1 for the speed limit value of the
parameter block.)
Circular interpolation arc error : The permissible circular arc error range is set.
(Refer to Section 6.4.3 for the allowable error range for
circular interpolation of the parameter block.)
[Program Example]
(1) The program which performs circular interpolation from the current position to
draw a half circle.
