Basic Functions
686 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
• The names of the geometry axes and special axes can be defined.
• The workpiece coordinate system can be translated, rotated, scaled or mirrored with FRAMES (TRANS, ROT,
SCALE, MIRROR).
Multiple translations, rotational movements, etc., are also possible.
Zero offset external
The zero offset external has the following properties:
• At a time defined in the PLC, a predefined additional zero offset between the basic and the workpiece
coordinate systems is activated.
• The magnitudes of the offsets can be set by the following for each of the axes involved:
-PLC
- Operator Panel
- Part program
• Activated offsets take effect at the instant the first motion block of the relevant axes is processed after offset
activation. The offsets are superimposed on the programmed path (no interpolation).
The velocity, at which the zero offset external is applied, is as follows:
Programmed F value plus +1/2 JOG velocity
The zero offset external is traversed at the end of G0 blocks.
• The activated offsets are retained after RESET and end of program.
• After POWER ON, the last active offset is still stored in the control but must be reactivated by the PLC.
