Allow the motor 

to cool down 

 
 

(entered in °C) 

The motor ambient temperature is entered at the instant that motor data is 
being determined (factory setting: 20 °C).

The difference between the motor temperature and the motor ambient 
temperature must lie in the tolerance range of approx. ± 5 °C. If this is not 
the case, then the motor data identification routine can only be carried-out 
after the motor has cooled down.
