Pulse enable is signaled by the PLC for this drive (axis/spindle).
The pulses for the drive modules are only enabled if all enable signals (hardware and software) are
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
edge change
1 → 0
The pulses are disabled by the PLC for this drive.
If pulse enable is canceled for a moving axis/spindle the axis/spindle is not longer braked in a
controlled fashion. The axis coasts to rest.

If pulse enable is canceled for a moving axis/spindle as a result of an EMERGENCY STOP, the
axis/spindle only coasts to rest.

2.1.9 Signals from axis/spindle (DB31, ...)
DB31, ...
DBX61.0
Drive test travel request
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The control signals that all of the traversing conditions for the drives are fulfilled.
Prerequisites for this are:
• 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.
Signal state 0 or
edge change
1 → 0
The control signals that the axes cannot be moved.
Axes cannot be moved for:
• DB31, ... DBX61.0 (drive test, travel request) = 0 signal
• in the control when faults are present
This means that the prerequisites specified above are not fulfilled.
