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
Composite speed" is set in " Pr.20 Interpolation speed designation method"
... The "Outside linear movement amount range error (error code: 504)" occurs
at a positioning start.
(The maximum movement amount that can be set in "
address/movement amount" is "1073741824 (=2
Positioning data setting example
[Reference axis is designated as axis 1.]
The following table shows setting examples when "3-axis linear interpolation
control (INC linear 3)" is set in positioning data No. 1 of axis 1. (The required
values are also set in positioning data No. 1 of axis 2 and axis 3.)
