Gear Stages - Siemens SINUMERIK 802D sl Programming And Operating Manual

Programming
3.4 Spindle movements
Exception: First movement of the spindle, i.e. if the measuring system is not yet synchro-
nized. In this case, the direction is specified in machine data.
Other movement specifications for the spindle are possible with SPOS=ACP(...),
SPOS=ACN(...), ... as for rotary axes.
The movement takes place in parallel with any axis movements in the same block. This
block is ended when both movements are finished.

Gear stages

Functionality
Up to 5 gear stages can be configured for a spindle for speed / torque adaptation. The rele-
vant gear stage is selected in the program via M commands:
● M40 ; Automatic gear stage selection
● M41 to M45; Gear stages 1 to 5
3-54
; Absolute position: 0 ... <360 degrees
; Absolute dimensions, approach position in positive
direction
; Absolute dimensions, approach position in negative
direction
; Incremental dimensions, leading sign determines the
traversal direction
; Absolute dimensions, approach position directly (on
the shortest path)
; Spindle position 14.3 degrees
; Positioning spindle with axis movements. This block is
ended when all movements are finished.
; The N81 block only begins once the spindle position
from N80 is reached.
