0x2D4C | 0x354C - Motor utilisation (I²xt): Parameter for the thermal model
Calculation with only one time constant
If k1 = "0 %" is set, the part of the winding is not taken into consideration and the thermal model is
only calculated using the time constant set for the housing/laminated core. This setting is e.g.
required if only the time constant of the laminated core (T2) is known.
