Table Of Compensation Values (Kw.ssfk.table[I].*) - Beckhoff TF5200 Manual

General compensation value data (kw.*)
3.3.10

Table of compensation values (kw.ssfk.table[i].*)

Compensation values are specified in the table 'kw.ssfk.table[i].*' The array index i may assume a number of
values determined by P-COMP-00020 [} 26] . Compensation values are specified as absolute position errors
in the unit specified in P-COMP-00017 [} 25] .

The table of compensation values contains the following elements.
3.3.10.1 Compensation value in positive direction (P-COMP-00023)
P-COMP-00023 Compensation value in positive direction
Description This parameter defines a compensation value in case of movement in positive
direction at interpolation point 'i'.
Parameter kw.ssfk.table[i].pos
Data type SGN32
Data range MIN(SGN32) ≤ pos < MAX(SGN32)
Axis types T, R, S
Dimension T: 0.1 µm or increments
Default value 0
Remarks
3.3.10.2 Compensation value in negative direction (P-COMP-00024)
P-COMP-00024 Compensation value in negative direction
Description This parameter defines a compensation value in case of movement in negative
direction at interpolation point 'i'.
Parameter kw.ssfk.table[i].neg
Data type SGN32
Data range MIN(SGN32) ≤ neg < MAX(SGN32)
Axis types T, R, S
Dimension T: 0.1 µm or increments
Default value 0
Remarks
3.3.10.3 Interpolation points of the axis (P-COMP-00025)
P-COMP-00025 Interpolation points of the axis
Description This parameter determines the interpolation points of the axis for which the axis
must be corrected.
Parameter kw.ssfk.table[i].setpoint
Data type SGN64
Data range MIN(SGN64) ≤ setpoint < MAX(SGN64)
Axis types T, R, S
Dimension T: 0.1 µm or increments
Default value 0
Remarks In CNC Builds V2.11.20xx and higher, the data type is SGN32 and so is the related
data range.
