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 (=230)" when "0:

Composite speed" is set in " 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 (=230)".)

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.)
