Restrictions
An error will occur and the positioning will not start in the following cases. The
machine will immediately stop if the error is detected during a positioning control.
•
When the movement amount for each axis exceeds "1073741824 (=2
An error "outside linear movement amount range" (error code: 504) will occur at
the positioning start.
(The maximum movement amount that can be set in " Da.5 Positioning
address/movement amount" is "1073741824 (=2
Positioning data setting example
The following table shows setting examples when "2-axis linear interpolation
control (ABS linear 2)" is set in positioning data No. 1 of axis 1. (The required
values are also set in positioning data No. 1 of axis 2.)

POINT
The speed limit does not function for the speed calculated by the AD75 during
interpolation control. Because of this, observe the following precautions when
setting the speed.
•
When the "composite speed" is set, set a value so the speed for each axis does
not exceed the " Pr.7 Speed limit value".
•
When the "reference axis speed" is set, set so the major axis side becomes the
reference axis. If the minor axis side is set as the reference axis, the major axis
side speed may exceed the " Pr.7 Speed limit value".
Setting details
Set "Positioning complete" assuming the next positioning
data will not be executed.
Set absolute system 2-axis linear interpolation control.
Designate the value set in " Pr.26 Acceleration time 1" as
the acceleration time at start.
Designate the value set in " Pr.9 Deceleration time 0" as
the deceleration time at deceleration.
Set the end point address. (Assuming "mm" is set in
" Pr.1 Unit setting".)
Setting not required (setting value will be ignored).
Set the speed during movement to the end point address.
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 auxiliary operation commands are
issued in combination with the No. 1 positioning data.
