6 MOTION PROGRAMS FOR POSITIONING CONTROL
[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.)
[Program Example]
(1) The program which draws a circular arc of more than 180° at a negative circular
arc radius (R) value.

REMARK
(1) The end point coordinates and circular arc radius cannot be omitted.
Always specify the end point coordinates and circular arc radius.
(2) Circular interpolation includes the [degree] axis whose stroke limit is set to be
invalid cannot be executed.
(3) Circular interpolation in the unit combination of [mm] and [degree] or [inch] and
[degree] cannot be executed.
