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)
