10.6.4 Speeds and setpoint adjustment for spindle
Speeds, gear stages
In SINUMERIK solution line, data for five gear stages are implemented. These stages are
defined by a minimum and maximum speed for the stage itself and by a minimum and
maximum speed for the automatic gear stage changeover.
A new set gear stage is output only if the new programmed speed cannot be traversed in the
current gear stage. For the sake of simplification, the oscillation times for gear stage
changeovers can be specified directly in the NC; the oscillation function must otherwise be
implemented in the PLC. The oscillation function is initiated via the PLC.
