Motor data
In the parameterisation dialog, the data of the motor nameplate for the selected motor are
displayed under "Motor data".
Actual values
When an online connection to the inverter has been established, the following actual values are
displayed in the parameterisation dialog under "Actual values":
Adapting motor data manually
If a third party manufacturer's motor is used, the displayed motor data can exactly be adapted to
the real motor by clicking the From project... button and selecting the "Own motor settings" entry
from the Motor selection dialog box afterwards. For this purpose, the data of the motor nameplate
and the equivalent circuit diagram must be available.
Tip!
For a better concentricity factor, we recommend to perform motor parameter
identification of the third party manufacturer's motor first. The motor parameters can be
manually adapted afterwards.
Improving the concentricity factor includes
• the adjustment of the inverter error characteristic to the drive system and
• the knowledge of the motor cable resistance.
Both factors are determined in the course of motor parameter identification.
