Sercos variables
13.14 Sercos variables
They are used in the data exchange via Sercos between the CNC and the drives.
Write variables
SETGE(X-C) SETGES SSETGS
The drive may have up to 8 gear ratios (0 through 7). Sercos identifier 218, GearRatioPreselection.
It may also have up to 8 parameter sets (0 through 7). Sercos identifier 217,
ParameterSetPreselection.
With these variables the work range or gear ratio and the parameter set of each drive may be
modified.
SETGE(X-C) ... for the axes.
SETGES ... for the main spindle.
SSETGS ... for the second spindle
The 4 least significant bits of these variables indicate the gear ratio and the other 4 the parameter
set to be selected.
Since it takes the drive some time to change the parameter set and the gear ratios, mark SERPLCAC
(M5562) will remain active from when the change is requested until the drive assumes the new
values. While this mark is on, no other change may be requested because the command would be
lost.
