Calculating the motor / control data

Internal motor / control data is calculated using parameter P0340 or, indirectly
using parameter P3900 (refer to Section 3.5.2) or P1910 (refer to Section 3.5.4).
The functionality of parameter P0340 can, for example, be used if the equivalent
circuit diagram data (refer to Fig. 3-23) or the moment of inertia values are known.
The following settings are possible for P0340:
0 No calculation
1 Complete parameterization
2 Calculation of the equivalent circuit diagram data
3 Calculation of V/f and Vector control
4 Calculation of the controller settings
For the complete parameterization (P0340 = 1), in addition to the motor / control
parameters, parameters are also pre-assigned which refer to the motor rated data
(e.g. torque limits and reference quantities for interface signals). A complete list of
all of the parameters depending on P0340 is included in the parameter list (refer to
parameter P0340).
When calculating the motor / control data using P0340, there are different
scenarios (refer to the following structogram), which can be called-up as a function
of the known data.
NOTE
When exiting the quick commissioning with P3900 > 0 (refer to Section 3.5.2),
internally P0340 is set to 1 (complete parameterization).
For the motor data identification (refer to Section 3.5.4), after the measurement
has been completed, internally P0340 is set to 3.

Calculation of motor parameters
P0340 = 1
This parameter is required during commissioning in order to optimize
the operating behavior of the drive inverter. For the complete
parameterization (P0340 = 1), in addition to the motor / control
parameters, parameters are pre-assigned which refer to the rated
motor data (e.g. torque limits and reference quantities for interface
signals). A list of the parameters, which are calculated, depending on
the setting of P0340, are included in the parameter list.
