12.4.2 Change the gear and set of a Sercos drive using variables.
The following variables may be used to change the gear and set of a Sercos drive for axes
and for spindles. This variable does not affect the parameter set of the CNC.
Programming.
The drive can have 8 work ranges or gears identified from 0 through 7 (drive parameter GP6)
and 8 sets of parameters (drive parameter GP4) identified from 0 through 7.
The 4 least significant bits indicate the work range and the 4 most significant bits indicate
the set of parameters. If the value of any 4-bit set is ·0·, the CNC does not change the active
gear or set at the drive. Example of some values of the variable.
Considerations.
Only one change can be taking place at a time. If other gear or set changes are programmed
during this process, even if they are at different drives, the CNC only keeps the one
programmed last and ignores the rest of the intermediate changes.

(V.)[ch].SP.SETGE.sn Select the set and the gear at the Sercos drive.
Value. Meaning.
$21 First range or gear (gear ·0·).
Second set of parameters (set ·1·).
$40 The drive maintains the active gear.
Fourth set of parameters (set ·3·).
$07 Seventh range or gear (gear ·6·).
The drive maintains the active parameter set.
