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 "2-axis linear interpolation control (INC linear 2)" is set in positioning data
No. 1 of axis 1]
• Reference axis ............. Axis 1
• Interpolation axis.......... Axis 2 (The required values are also set in positioning
data No. 1 of axis 2.)
