G69: Program Coordinate Rotation Mode Cancel - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

G69: Program coordinate rotation mode cancel

Cancels the set program coordinate rotation offset.
Code
G69
Processing details
• The G69 command cancels the set program coordinate rotation mode start (G68) and ends program coordinate rotation
mode.
• Movement commands immediately after G69 command must be made in absolute value command mode. When made in
incremental value mode, a minor error (error code: 1FC3H (details code: 0327H)) occurs.

Remarks
Move to "X0, Y0" of the work coordinate system 1 by absolute value command
Set the local coordinate system offset "X1500, Y1000" (no axis movement)
Set "X-500, Y0" of the local coordinate system as the center of rotation, and rotate
coordinates counterclockwise by -60[degree]
Move to "X-500, Y0" on the local coordinate system after rotation performed in (3)
Move to "X-500, Y250" on the local coordinate system after rotation performed in (3)
Move to "X-1000, Y250" on the local coordinate system after rotation performed in (3)
Move to "X-1000, Y-250" on the local coordinate system after rotation performed in (3)
Move to "X-500, Y-250" on the local coordinate system after rotation performed in (3)
Move to "X-500, Y0" on the local coordinate system after rotation performed in (3)
