Caution: Motor identification should 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 5°C limit then the correct functioning of Vector Control (SLVC) cannot be
guaranteed.
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, irrespec-
tive of whether the motor is connected star or delta.
This must be considered when the motor data is inputed directly.
