Calculating The Motor And Control Data - Siemens SINAMICS G120 Operating Instructions Manual

If Problems occur during the identification run, for example, the current controller oscillates,
then the rating plate data should be re-checked and an approximately correct magnetizing
current P0320 entered. The motor data identification routine should then be re-started by
called P0340 = 1.
Step-by-step table for motor data identification see section "Quick commissioning".

Calculating the motor and control data

Overview
Internal motor/control data is calculated using parameter P0340 or, indirectly using
parameter P3900 or P1910. The functionality of parameter P0340 can, for example, be used
if the equivalent circuit diagram data or the moment of inertia values are known. The
following settings are possible for P0340:
0
1
2
3
4
For the complete parameterization (P0340 = 1), in addition to the motor and control
parameters, parameters are also pre-assigned which refer to the motor rated data (for
example, torque limits and reference quantities for interface signals). A complete list of all of
the parameters depending on P0340 is included in the parameter manual.
When calculating the motor/control data using P0340, there are different scenarios, which
can be called-up as a function of the known data.
Note
When exiting quick commissioning with P3900 > 0, internally P0340 is set to 1 (complete
parameterization).
For the motor data identification, after the measurement has been completed, internally
P0340 is set to 3.
