DB31, ...
DBX60.0 Spindle/no axis
Signal state 0 or The machine axis is operated as an axis
edge change
The interface signals to the axis (DB31, ... DBB12 - DBB15) and from the axis
1 → 0
(DB31, ... DBB74 - DBB81) are valid.
The interface signals to the spindle (DB31, ... DBB16 - DBB19) and from the spindle
(DB31, ... DBB82 - DBB91) are invalid.
Application If a machine axis operates alternatively as a spindle or rotary axis:
example(s)
•
•
The currently active operating mode
can be identified from interface signal:
DB31, ... DBX60.0 (spindle/no axis).
DB31, ...
DBX82.3 Change gear stage
Edge evaluation: yes
Specification of gear stage:
•
•
Signal state 1 or New set gear stage was specified AND
edge change set gear stage <> actual gear stage
0 → 1
Special cases, Signal is not output if: Set gear stage == actual gear stage
errors, ......
Corresponds to .... DB31, ... DBX82.0 - DBX82.2 (set gear stage A to C)
DB31, ... DBX16.0 - 16.2 (actual gear stage A to C)
DB31, ... DBX16.3 (gear is changed)

Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Turning machine: spindle/C axis
Milling machine: spindle/rotary axis for rigid tapping
Signal(s) updated: cyclic
Manual specification using M function M41 - M45 corresponding to gear stage 1 - 5
If set gear stage <> actual gear stage =>
DB31, ... DBX82.3 (change gear) = 1
DB31, ... DBX82.0 - DBX82.2 (set gear stage) = set gear stage
Automatic gear stage selection depending on the programmed spindle speed using M function
M40
If specified set speed requires gear stage change =>
DB31, ... DBX82.3 (change gear) = 1
DB31, ... DBX82.0 - DBX82.2 (set gear stage) = set gear stage
