In accordance with the following formula the leakage inductance σL
0,00...500,00 mH is entered in parameter dr.7. In case the data is not specified in
the data sheet the motor manufacturers give further information.

If the leakage inductance is taken from a data sheet, then there is usually the
phase value for σL specified. Depending on the used connection the following
S
value must be entered in dr.7:
Star connection:
Delta connection: dr.7 = 2/3 x σL
