(3) Continuous path positioning
with speed change.................... Positioning is carried out successively in order of
data Nos. with one start signal. This positioning
control enables speed change during positioning.

Control system
Set the "control system" for carrying out positioning control.
(1) When "JUMP instruction" is set for the control system, the "dwell time" and "M
code" setting details will differ.
(2) When "LOOP" is set for the control system, the "M code" setting details will differ.
(3) Refer to Section 4.3.1 to 4.3.11 for details on the control systems.
(4) If "degree" is set for the unit setting, the circular interpolation control cannot be
carried out. (An error will occur when executed.)
Axis to be interpolated
Set the interpolation axis (target axis) only for operation under the 2-axis interpolation
control.
(This item does not need to be set in case where 3 or 4-axis interpolation is selected.)
(1) Do not specify the own axis or a value out of the setting range 1 to 4 for an
interpolation target axis. An error will occur when executed.
(2) The following shows the relationship between a reference axis and interpolation
axis according to control systems.
