slip increase only takes effect when temperature sensor that can be

evaluated was installed in the end winding of the motor.

The following values are depending on the cooling type of the motor:

Cooling type of the motor Value for P-0-0530

non-ventilated 1,4

ventilated 1,5

liquid-cooled 1,8

motor without temperature sensor 1,0

Fig. 5-50: Values for P-0-0530

With the value to be set in P-0-0529, Scaling of stall current limit it is

possible to change the stall current limit relatively.

→ value to be set is "100" (in %)

The value for parameter P-0-4036, Rated motor speed has to be taken

from the completed form "Output Data for Asynchronous Motors".

From the data of the stator and rotor leakage inductance and the motor

magnetizing inductance it is possible to determine more exact motor

parameter values than from the type plate data. It is therefore

advantageous to have these data supplied by the motor manufacturer.

The desired data are referring to the single-phase substitute connection

diagram of asynchronous motors with star connection reference.
