General compensation value data (kw.*)

Plane compensation (kw.crosscomp2.*)

Plane compensation allows the correction of an axis position depending on the actual positions of two axes.
The axis for which correction is active is called the slave axis. The two axes whose command positions
influence the compensation value are called master axes.
The data for plane compensation is defined in the compensation value list of the slave axis. General data of
the list body is entered in the structure kw.cross comp2.*. It contains the following elements.
3.2.1 Maximum number of table entries for plane compensation (P-
COMP-00061)
P-COMP-00061 Maximum number of table entries for plane compensation
Description This plane compensation parameter (FCT-C5) saves the memory space required for
a particular number of table entries.
The size of the actually used compensation table is defined by `last_index:master1`
(P-COMP-00010 [} 20]) and `last_index_master2` (P-COMP-00011 [} 20])
and the following must apply:
(`last_index_master1` + 1) * (`last_index_master2` + 1) <= `max_points`
If `max_points` is not specified (or assigned the value 0), the previous restrictions
apply to `last_index_master1` and `last_index_master2`.
• 0 <= `last_index_master1 [} 20]` <= 100
• 0 <= `last_index_master2 [} 20]` <= 100
Parameter kw.crosscomp2.max_points
Data type UNS32
Data range 0 <= P-COMP-00061
Axis types T, R, S
Dimension T: ----
Default value 10201 (*)
Remarks The parameter value can no longer be changed after start-up or after lists are
reloaded. Otherwise error ID 110640 is output.
If P-COMP-00061 is not specified (or assigned the value 0), the default value is
assigned to P-COMP-00061 for downward compatibility reasons.
To avoid the default assignment, memory can be saved for an axis that does not
use plane compensation by assigning the value 1 to P-COMP-00061.
* composition of the default value: 101*101 =10201
This parameter is available as of CNC Build V3.3079.06

Type of interpolation point grid (P-COMP-00031)

P-COMP-00031 Type of interpolation point grid
Description This parameter defines whether the identical interpolation point distance is used for
the two master axes or whether the distances for the two master axes are defined
individually.
