Tapping or thread cutting
The following applies to parameter sets for axes:
• For machine axes not involved in tapping or thread cutting, parameter set 1 (index=0) is
• For machine axes involved in tapping or thread cutting, the same parameter set number
The current parameter set is displayed in operating area "Diagnostics" in the "Service axis"
display. The parameter sets for gear stages 1 to 5 are referred to as interpolation
parameters.
Parameter sets during gear stage change
Interpolation parameter sets during gear stage change:
In the case of spindles, each gear stage is assigned its own parameter set.
The appropriate parameter set is activated, depending on the NC/PLC interface signal:
DB31, ... DBX16.0 - 16.2 (actual gear stage).
DB31, ... DBX16.0 - 16.2 (actual gear stage)
