09.95 12 Functional Descriptions
12.19.5 Interpolation and compensation with tables
3. G functions
From IKA Stage 2, an IKA configuration can be programmed in a part program using the
following G functions:
• G410 Deactivate IKA link branch
• G411 Define/delete IKA configuration
• G412 Activate/deactivate IKA link branch
If the IKA function is used in curve gearbox interpolation (CGI), it is parameterized in
• G400 Switch off GI/IKA link branch(es)
• G401 Define/delete GI/IKA configuration
• G402 Switch on/over/off GI/IKA link branch(es)
• G403 Synchronize GI/IKA link branch(es) in ascending order
This G function can only be used if gearbox interpolation has been installed via the machine
data.
Note:
You will find a detailed description of the G functions listed above in the Programming Guide
for SINUMERIK 840C.
Data access via MMC/data transfer
The IKA data are divided between 3 data files %IKA1, %IKA2, %IKA3. These data can be read
from and written to the hard disk via the RS 232 C (V.24) interface.
Data transfer
VRS 232 C workpiece NCK
can be made automatic with the function "Control of data transfer" (DB 37).
The files to be transferred have the following format if output in punched tape format:
• Output of IKA configuration
%IKA1
Ny TO = xxxxxxxx T1=x T2=x T3=x T4=x T15=x T16=x (up to SW 3)
Ny TO = xxxxxxxx T1=x T2=x T3=x T4=x T15=x T16=x T17=x T18=x
T19=x T20=x T25=x T26=x T31=x T32=x T33=x
: T34=x T44=x (SW 4 and higher)
