Ambient motor temperature (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.
