2.9 Sum offsets and setup offsets
Tool Compensation (W1)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-131
Supplementary conditions
The maximum number of DL data sets of a cutting edge and the total number of sum offsets
in the NCK are defined by machine data. The default value is zero, i.e., no sum offsets can
be programmed.
Activate the "monitoring function" to monitor a tool for wear or for "sum offset".
The additional sum/setup data sets use additional buffered memory. 8 bytes are required per
parameter.
A sum-offset data set requires: 8 bytes * 9 parameters = 72 bytes
A setup data set requires an equal amount of memory. A certain number of bytes is also
required for internal administration data.
2.9.3 Activation
Function
The function must be activated via a machine data.
System variables $TC_ECPx and $TC_SCPx and setup and sum offsets ("fine") defined via
the OPI interface can be activated in the part program.
This is done by programming the language command DL="number".
When a new D number is activated, either a new DL number is programmed or the DL
number defined in machine data:
MD20272 $MC_SUMCORR_DEFAULT
becomes active.
DL programming
The sum offset is always programmed relative to the active D number with the command:
DL = "n"
The sum offset "n" is added to the wear of the active D number.
Note
If you use "setup offset" and "sum offset fine", both compensations are combined and added
to the tool wear.
The sum offset is deselected with the command:
DL = 0
