2.3.2 Test requirements

Requirements on the control
When making measurements, the machine axes must be moved with precisely the
motion profile that is defined in the NC program. In addition, it must also be
guaranteed that the motion is also executed in the machine coordinates.
The following functions in the NCK could be problematical when carrying out
measurements (sample selection):
•
Asynchronous subprograms
•
Static synchronized actions
•
Axis couplings
•
Kinematic transformations
•
Superimposed (overlaid) motion, such as DRF, external work offset
•
Tool length compensation
•
Functions that influence the velocity, such as G95
•
Functions that change the position, such as DIAMON
•
Axis replacement / geometry axis replacement
•
Axis is passed over to the PLC (PLC axis)
The NC program for performing the measurement does not affect the functions
listed above. Only the zero offsets are disabled and the offset produced by DRF
and external zero offset is compensated statically, i.e. the value is corrected by the
value that applies at the beginning of the measurement.
Orientation transformations are a special case. It is possible to execute
measurements with the geometry axes when transformation is active. However, the
offset of the geometry axis coordinates produced by the orientation axes is not
compensated for. It is therefore advisable to deactivate transformation.
Couplings between axes should be separated before the measurement movement
(e.g. in the prolog program). The NC program of the system does not disconnect
couplings. SINUMERIK Integrate assumes that it is possible in a channel on the
machine to load, select, and start an NC program (with subprograms) that was
downloaded from the system. With machines where the PLC prevents the operator
from selecting or starting an NC program, the PLC can communicate with the
SINUMERIK Integrate system via DB10.DBB90 or DBB91.
Machine data must be set in the control to acquire data for the condition monitoring
measurements. Not only Trace Server machine data but also MD 36730:
DRIVE_SIGNAL_TRACKING must be set.
Drives that are linked via PROFIBUS must be handled differently. Here the
PROFIBUS configuration must be changed so that the torque values can be
transmitted to the control cyclically.
