Detailed Description
2.5 Toolholder with orientation capability
Basic logic functions: Tool Offset (W1)
106 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
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 the significance of the system variables $TC_CARR41 to $TC_CARR65 available for the
fine offset see:

Activation
The following setting adds the fine offset values to the basic values:
SD42974 $SC_TOCARR_FINE_CORRECTION = 1 (fine offset TCARR on/off)
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
• at the same time the following setting data is set:
SD42974 $SC_TOCARR_FINE_CORRECTION
