18.11 Oscillation (P5)
Extended Functions
900 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
DB31, ...
DBX28.7
PLC controls axis
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
Axis is controlled by the PLC.
The reaction to interface signals is controlled by the PLC by means of the 2 stop bits, other
signals with deceleration action are ignored.
Signal state 0 or
edge change
1 → 0
Axis is not controlled by the PLC.
Corresponding to .... DBX28.5, DBX28.6
18.11.2 Signals from axis/spindle (DB31, ...)
VDI output signals
The NCK makes the following signals available to the PLC user program.
DB31, ...
DBX100.2
Oscillation reversal active
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The deceleration period after external oscillation reversal (DB31, ...DBX28.0) is active
Signal state 0 or edge
change 1 → 0
No deceleration after external oscillation reversal is active
DB31, ...
DBX100.3
Oscillation cannot start
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The oscillation axis cannot be started owing to incorrect programming. This status can occur
even when axis has already been traversed.
Signal state 0 or edge
change 1 → 0
The oscillation movement can be started.
DB31, ...
DBX100.4
Error during oscillation movement
Edge evaluation: Signal(s) updated:
Signal state 1 or edge
change 0 → 1
The oscillation movement has been aborted.
Signal state 0 or edge
change 1 → 0
The oscillation movement is being executed correctly.
