Caution:

Motor identification should normally be performed on a cold motor. However, the identification of the motor data should only be performed if the motor temperature is within 5°C of the measured ambient temperature stored in P0625. If the motor identification is not within the 5ºC limit then the correct functioning of Vector Control (VC, SLVC) cannot be guaranteed. This may cause instabilities when using vector control.

The motor rating plate information with respect to the connection of the motor windings (Star or delta connection) must be correct in order to establish the correct equivalent circuit data. The motor identification calculates this data based on a Phase of a Star equivalent circuit P0350 - P0360, irrespective of whether the motor is connected star or delta. This must be considered when the motor data is input directly.

Note:

-In order to that the motor identification routine supplies the correct data, before selecting, fast commissioning should be carried-out.

-If the motor data identification routine is activated (e.g. P1910 = 1), then at the next ON command, the measuring operation is started and alarm A0541 is generated. After the measurement is completed, both P1910 and the alarm are reset.
