09.95 12 Functional Descriptions
12.19.5 Interpolation and compensation with tables
12.19.5.4 Activating IKA data
%IKA1
The IKA data of %IKA1 are active immediately.
%IKA2 und %IKA3
Changes to %IKA2 and %IKA3 must be activated separately.
Once all the IKA data have been entered in %IKA2 and %IKA3 all the compensation curves
are calculated with the signal "Warm restart". When the data are loaded into the MMC on
Power On, the compensation curves are calculated by the control automatically.
• From SW4 the individual curves can also be selected and calculated by operating the
softkey "IKA curves".
• From IKA Stage 2, individual curves can be selected and calculated in the part program
with parameter 55.
Notes:
• If an error occurs the control outputs an alarm which does not, however, cause a
processing stop. An error scan must be implemented by the user (see example of
calculation of compensation curves).
• If configuration curves %IKA2 and %IKA3 that are currently active are changed, traversing
errors will occur until they are converted.
