Chapter 9 Major Positioning Control
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 operation.
If the movement amount of each axis exceeds "1073741824 (=2
30
)" when "0:
Composite speed" is set in "[Pr.20] Interpolation speed designation method"
The error "Outside linear movement amount range" (error code: 504) occurs at
a positioning start.
(The maximum movement amount that can be set in "[Da.6] Positioning
address/movement amount" is "1073741824 (=2
30
)".)
Positioning data setting example
[When "3-axis linear interpolation control (INC linear 3)" is set in positioning data
No. 1 of axis 1]
• Reference axis ............. Axis 1
• Interpolation axis.......... Axis 2, Axis3 (The required values are also set in
positioning data No. 1 of axis 2 and axis 3.)

[Da.3]
Acceleration time No. 1 – – 1 – –
Designate the value set in "[Pr.25]
Acceleration time 1" as the
acceleration time at start.
[Da.4]
Deceleration time No. 0 – – 0 – –
Designate the value set in "[Pr.10]
Deceleration time 0" as the
deceleration time at deceleration.

When axis 1 is used as a reference
axis, the interpolation axes are axes
2 and 3.
