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.
Figure 10-21 Example for speed ranges for automatic gear stage selection (M40)
Speeds for conventional operation
The speeds of the spindle in conventional mode are entered in the machine data:
● MD32010 JOG_VELO_RAPID (rapid traverse in jog mode)
● MD32020 JOG_VELO (JOG axis velocity)
The direction of rotation is specified via the appropriate directional keys for the spindle on the
MCP.
Direction of rotation
The direction of rotation of a spindle corresponds to the traversing direction of an axis.
