Parameterization and commissioning
Fig. 111: Configuration, linking of axes
If required for control or diagnostics, CU and Active Line Module are linked with variables (structures) of a
PLC project (which have to be created).
Verifying Profibus MC times
Once the NC and the fieldbus have been configured, in online mode press the button "Calculate MC Times"
in the MC tab of the master card FC31xx (I/O configuration) and note any warnings. The "Estimated DP
Cycle Time" for all axes must be smaller than the NC task time referred to above. A safety margin of approx.
10% should prevail.
Reading parameters from PROFIdrive MC
The following step takes place during commissioning and requires the existence of parameterized axes and
a functional fieldbus for the PROFIdrive MC axis system.
