Detailed Description
2.5 Toolholder with orientation capability
Tool Compensation (W1)

Fine offset
The offset vectors l
1
to l
4
and the offsets of the rotary axes v
1
and v
2
can be represented as
the sum of a basic value and a fine offset. The fine offset parameters assigned to the basic
values are achieved by adding a value of 40 to the index of the basic value.
Example:
The parameter $TC_CARR5 is assigned to the fine offset $TC_CARR45.
Note
For more information about the meaning of system variables $TC_CARR41 to
$TC_CARR65, which are available for the fine offset, please refer to:

/PGA/ Programming Guide, Production Planning; Tool Compensations.
Activation
The fine offset values are added to the basic values if
SD42974 $SC_TOCARR_FINE_CORRECTION = 1.
Supplementary conditions
The amount is limited to the permissible fine offset.
The maximum permissible value is defined:
For: With machine data:
• The components of vectors l
1
to l
4
:
MD20188 $MC_TOCARR_FINE_LIM_LIN
• The offsets of the two rotary axes v
1
and v
2
:
MD20190 $MC_TOCARR_FINE_LIM_ROT
An illegal fine offset value is only detected when:
• A toolholder with orientation capability, which contains such a value, is activated
and
• Setting data:
SD42974 $SC_TOCARR_FINE_CORRECTION
is enabled simultaneously.
