Further information
Setting offset values
On the operator panel or universal interface, enter the following values in the internal control
zero offset table:
• Coordinates for the offset
• Angle for rotated clamping
• Scaling factors (if required)
Zero offset G54 to G57
The call of one of the four commands G54 to G57 in the NC program moves the zero point
from the basic coordinate system to the workpiece coordinate system.
In the next NC block with a programmed movement, all of the positional parameters and thus
the tool movements refer to the workpiece zero, which is now valid.
