8.2 Zero offset tables
This table stores the zero offsets for each axis. There are up to 20 absolute zero
offsets and a special one for the PLC.
Although the table is common to all the channels, when accessing from a channel,
it only shows the axes of that channel. The offsets of other channels may be accessed
from the vertical softkey menu.
A. Machine axes and display units (millimeters, inches or degrees).
B. Zero offsets.
C. Zero offset value in each axes of the channel.
The end of this chapter describes how to edit this table.
PLC offset
It cannot be directly defined in the table. The values are set from the PLC or from the
part-program using high-level variables.
It is used, for example, to correct deviations originated by machine dilatations.
The CNC always adds the PLC offset to the selected zero offset.
Absolute zero offsets
Besides setting the values directly in the table, they may also be set from the PLC
or via part-program using high-level variables.
The zero offsets are used to place the part zero at different positions of the machine.
When applying a zero offset, the CNC assumes as the new part zero the point set
by the selected zero offset referred to the clamp zero (if active).
To apply an absolute zero offset, it must be activated via program using the relevant
function.
