Commissioning
5.5 Commissioning using the BOP
Manually Calculating the Motor and Control Data
The internal motor/control data are 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.
Note
When exiting quick commissioning with P3900 > 0, internally P0340 is set to 1 (complete
parameterization).
If the measurements of the motor data identification are completed, P0340 is internally set to
3.
Performing the calculation of motor and control data via BOP
Parameter Description
P0340 = 1 Calculation of motor parameters
This parameter is required during commissioning in order to optimize the operating behavior of
the 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.
0: No calculation
1: Complete parameterization (default)
2: Calculation of equivalent circuit data
3: Calculation of V/f and Vector control
4: Calculation of controller settings only
If additional catalog data is known enter the data in P0341, P0342 and P0344.
P0341 = ... Motor inertia [kg*m
P0342 = ... Total/motor inertia ratio
P0344 = ... Motor weight (entered in kg)
If the ECD data is known, enter the data in P0350, P0354, P0356, P0358, P0360.
If the ECD data is not known, then: Set P0340 = 4 to calculate the controller settings and skip to END.
P0350 = ... Stator resistance (line) (entered in Ω)
Stator resistance in Ω of the motor which is connected (line). This parameter value doesn't
include the cable resistance.
P0352 = ... Cable resistance cable resistance in Ω between inverter and motor for one phase
