09.95 12 Functional Descriptions
12.19.5 Interpolation and compensation with tables
Weighting input A, numerator
Data type: 18 Input format: ±99 999 999
Weighting input A, denominator
Data type: 19 Input format: ±99 999 999
By entering the numerator and denominator, it is possible to stretch and compress a
compensation curve. The offset of the modulo values and the start position of the IKA
configuration then refer to this value.
Input B (number) Data type: 25
An axis or R parameter no, is set depending on the type of input quantity B. Input B
multiplies the output. Weighting is also possible via the weighting factors of the output.
Input B (type) Data type: 26
The axis type consists of the parameter group and the parameter value. For a more
detailed explanation see, for example, Programming Guide for SINUMERIK 840C, Section
Programming cycles under @30c and @40c.
Note:
Input A is automatically preset with G function G411/G401. Display in the machine data
dialog is in plaintext.
Output (number) Data type: 3
Depending on the type of output quantity, either the axis, R parameter or channel no. is
active.
Output (type) Data type: 33
The axis type consists of the parameter group and the parameter value. For a more
detailed explanation see, for example, Programming Guide for SINUMERIK 840C, Section
Programming cycles under @30c and @40c.
Weighting factor output A, numerator
Data type: 4 Input format: ±99 999 999
Weighting factor output A, denominator
Data type: 30 Input format: ±99 999 999
Any multiplication factor can be generated for the output quantity by entering a numerator
and denominator. Weighting of input B is also possible.
• %IKA3, IKA compensation points
Input quantity value
The input quantity value determines the compensation point on the basis axis.
Output quantity value
The output quantity value determines the compensation point on the relevant position of
the basis axis.
