Detailed Description
2.9 Sum offsets and setup offsets
Basic logic functions: Tool Offset (W1)

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 the machine data:
MD18108 $MN_MM_NUM_SUMCORR (sum offsets in TO area).
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 via the following machine data becomes active:
MD20272 $MC_SUMCORR_DEFAULT (basic setting of the additive offset without a
program)
