12.18.15 Gearbox interpolation status data
In the SINUMERIK 840C control system, the currently valid configuration and status data of the
active and inactive GI groupings are stored in the so-called gearbox interpolation (GI) status
data. A memory area is reserved for each axis and spindle because every axis/spindle could
be a following axis/spindle. The memory area is buffered so that the gearbox configurations are
not lost after power off. The data are read after power on and the link activated during ramp-up
(used for gantry axes) provided that the enabling command is present (NC MD 1844*/525*
LINK ON after POWER ON). The GI status data can be erased in general reset mode.
These data lists can be read in or out as %GIA data via the RS 232 C (V.24) interface. Data
can be read in only in start-up mode and read out only when the SINUMERIK is in the reset
state.
