3.3.3
Carrying out commissioning
Preconditions for commissioning
the smoothing reactors are available and are dimensioned correctly (see Chapter
Dimensioning of the smoothing reactors (Page 19)) and
the parameter for the rated motor current (p50100) is set correctly at all of the partial
converters.
WARNING
The thyristors may be destroyed, if the inductance of the smoothing reactor is too low.
Commission the master converter
and
the slave converter as described in the SINAMICS
DCM DC converter operating instructions (commissioning steps 1 up to and including 8):
When commissioning with the BOP20 operator panel:
Perform commissioning steps
When commissioning with the AOP30 operator panel:
Execute "Drive commissioning" menu command
When using the STARTER commissioning tool for commissioning:
Start the project wizard
Note
For a 12
-pulse parallel connection, we recommend to switch over the method of calculating
the EMF calculation for the armature current precontrol to p5
0162 = 4 (EMF calculated from
the speed actual value). Reason: Contrary to the EMF calculation method according to the
factory setting p50162 = 1 (measured EMF), this calculation method is not dependent on the
parameterized values of the inductances.
3.3.4
Optimization runs
The optimization runs should only be carried out on the master converter. The slave
converters must be connected and ready for operation.
When optimizing the armature current control, a distinction has to be made as to whether an
interphase transformer is being used as smoothing reactor, or whether 2 individual reactors
are being used.
