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.
