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

Note
SINAMICS S120: Message word (MELDW)
The message word (MELDW) is only contained in PROFIdrive telegrams compatible with
SIMODRIVE 611U, for example, telegrams 102, 103, 105, 106, 110, 111, 116, 118, 125, 126,
136, 138, 139

SINAMICS S120: Status word 1/2 (ZSW1/2)
The status words ZSW1 or ZSW2 only refer to SIMODRIVE 611U compatible PROFIdrive
telegrams in the following (SIMODRIVE 611U interface mode, p2038 = 1)
DB31, ...
DBX61.0 Drive test travel request
Edge evaluation: No
Signal state 1 The control signals that all of the traversing conditions for the drives are fulfilled.
Requirements for this are:
● The mechanical brake of the axis involved was previously released and all other axis traversing
● The axis disable:
Signal state 0 The control signals that the axes cannot be moved.
Axes cannot be moved when:
● DB31, ... DBX61.0 (drive test, travel request) = 0 signal
● Faults are present in the control
This means that the requirements specified above are not fulfilled.

Signal(s) updated: Cyclically
conditions are fulfilled.
With:
DB31, ... DBX61.0 (drive test, travel request) = 1 signal
the appropriate axes can be moved.
DB31, ... DBX1.3 (axis/spindle disable) = 1 signal
is not active.
