(2) Restrictions
• The axis error "Continuous path control not possible" (error code: 516) will occur and the operation cannot
start if "continuous path control" is set in "[Da.1] Operation pattern". ("Continuous path control" cannot be set
in fixed-feed control.)
• If the movement amount of each axis exceeds "1073741824 (=2
"[Pr.20] Interpolation speed designation method", the error "Outside linear movement amount range" (error
code: 504) occurs at a positioning start and positioning cannot be started. (The maximum movement amount
that can be set in "[Da.6] Positioning address/movement amount" is "1073741824 (=2
• "Fixed-feed" cannot be set in "[Da.2] Control system" in the positioning data when "continuous path control"
has been set in "[Da.1] Operation pattern" of the immediately prior positioning data. (For example, if the
operation pattern of positioning data No. 1 is "continuous path control", fixed-feed control cannot be set in
positioning data No. 2.) The axis error "Continuous path control not possible" (error code: 516) will occur and
the machine will carry out a deceleration stop if this type of setting is carried out.
(3) Positioning data setting example (Reference axis is designated as axis 1.)
The following table shows setting examples when "3-axis fixed-feed control (fixed-feed 3)" is set in positioning
data No. 4 of axis 1. (The required values are also set in positioning data No. 1 of axis 2 and axis 3.)

example
Set "Positioning complete" assuming that the next
positioning data will not be executed.
Set 3-axis fixed-feed control.
Designate the value set in "[Pr.25] Acceleration time
1" as the acceleration time at start.
Designate the value set in "[Pr.10] Deceleration time
0" as the deceleration time at deceleration.
Setting not required. (Setting value will be ignored.)
When axis 1 is used as a reference axis, the
interpolation axes are axes 2 and 3.
Set the movement amount. (Assuming "mm" is set in
6000.0m
"[Pr.1] Unit setting".)
Setting not required. (Setting value will be ignored.)
Set the speed during movement.
Set the time the machine dwells after the positioning
stop (pulse output stop) to the output of the
positioning complete signal.
Set this when other sub operation commands are
issued in combination with the No. 1 positioning
data.
