Signals From Axis/Spindle (Db31 - Siemens SINUMERIK 840D sl Function Manual

DB31, ...
DBX21.7
Pulse enable
Edge evaluation: no
Signal state 1 or Pulse enable is signaled by the PLC for this drive (axis/spindle).
edge change
The pulses for the drive modules are only enabled if all enable signals (hardware and software) are
0 → 1
available (see figure for DB31, ... DBX93.5).
In this case, the interface signal:
DB31, ... DBX93.7 (pulses enabled)
is signaled to the PLC with a signal.
For additional information refer to DB31, ... DBX93.7 and references.
Signal state 0 or The pulses are disabled by the PLC for this drive.
edge change
If pulse enable is canceled for a moving axis/spindle the axis/spindle is not longer braked in a
1 → 0
controlled fashion. The axis coasts to rest.
Signal irrelevant for SINUMERIK FM-NC
...
Application Signal relevant to safety
example(s)
Special cases, If pulse enable is canceled for a moving axis/spindle as a result of an EMERGENCY STOP, the
errors, .... axis/spindle only coasts to rest.
Corresponding to .... DB31, ... DBX93.7 (pulses enabled)

Signals from axis/spindle (DB31, ...)

DB31, ...
DBX61.0 Drive test travel request
Edge evaluation: no
Signal state 1 or The control signals that all of the traversing conditions for the drives are fulfilled.
edge change
Prerequisites for this are:
0 → 1
•
•
Signal state 0 or The control signals that the axes cannot be moved.
edge change
Axes cannot be moved for:
1 → 0
•
•
This means that the prerequisites specified above are not fulfilled.

Signal(s) updated: cyclic
Signal(s) updated: cyclic
The mechanical brake of the axis involved was previously released and all other axis traversing
conditions are fulfilled.
With:
DB31, ... DBX61.0 (drive test, travel request) = 1 signal
the appropriate axes can be moved.
The axis disable:
DB31, ... DBX1.3 (axis/spindle disable) = 1 signal
is not active.
DB31, ... DBX61.0 (drive test, travel request) = 0 signal
in the control when faults are present
