Activation of IKA Stage 2
The option IKA Stage 2 applies from SW 4 and contains the IKA option. With IKA Stage 2 it is
possible not only to implement compensations but also any (non-linear) interpolations.
The options for presetting the input and output quantity have been expanded in IKA Stage 2 for
use with interpolation.
An input can be:
• Axis setpoint position
• Axis actual position
• R parameters
An output can be:
• Axis setpoint position
• Axis compensation value
• R parameters
• Feed weighting
Since it is now possible to parameterize R parameters for both input quantities and output
quantities, the user is able to cascade IKA tables (see following diagram).
