11.5.24 Speeds and setpoint adjustment for spindle
In SINUMERIK 840Di sl, 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 NCK; other-
wise the oscillation function must be implemented in the PLC. The oscillation
function is initiated via the PLC.

The speeds of the spindle in conventional mode are entered in the machine
data:
S MD32010: JOG_VELO_RAPID (rapid traverse in JOG mode)
S MD32020: JOG_VELO (JOG axis velocity)
The direction of rotation is specified via the appropriate directional keys for the
spindle on the MCP.
The direction of rotation of a spindle corresponds to the traversing direction of
an axis.
The speeds must be transferred with standardized values for the drive control-
ler. The values are scaled in the NCK using the selected load gear and the ap-
propriate drive parameter.
