7. POSITIONING CONTROL
7 − 6
POINTS
(1) Reference axis speed and positioning speed of other axes
• Note that the positioning speed of an axis with a greater travel value than the reference axis will
exceed the set reference axis speed.
(2) Indirect designation of reference axis
• The reference axis can be indirectly designated using word devices D and W. See Section
6.4.2.
(3) Relationship between speed limit value, acceleration time, deceleration time, and rapid stop
deceleration time
• The real acceleration time, deceleration time, and rapid stop deceleration time are determined
by the reference axis speed setting.

Under circular interpolation control, the angular speed is controlled to the set
speed.
