Tapping, thread cutting
For tapping or thread cutting, the following applies with regard to the parameter sets of axes:
● For machine axes that are not involved in tapping or thread cutting, parameter set 1 (index
= 0) is active. The other parameter sets do not have to be taken into account.
● For machine axes that are involved in tapping or thread cutting, the same parameter set
number as that of the current gear stage of the spindle is active.
All parameter sets correspond to the gear stages and must therefore be parameterized.
The current parameter set is displayed on the user interface at:
Operating Area "Diagnostics" > "Service axis"
Parameter sets during gear stage change
Each gear stage of a spindle is assigned a separate parameter set. The gear stage is selected
via the following NC/PLC interface signal:
DB31, ... DBX16.0 - 2 = <actual gear stage>
For further information on gear stages for spindles, see Section "S1: Spindles (Page 733)".
