<1> For KTY and PTC, the value p0606 = 0 has a different meaning:
KTY: 0 The output of the timer is always switched out (logical 0)
PTC: 0 Delay time = 0 s
<2> Switch-on delay p0607 = 0 suppresses fault F07016.
<3> For KTY and "No sensor", temperature as defined in the model.
<4>
p0610 = 0 : No response, only warning, no reduction of I_max
1 : Warning and reduction of I_max and fault (F07011)
2 : Warning and fault, no reduction of I_max
<5>
The relevant rated response temperature in °C depends on the temperature sensor
chosen by the motor manufacturer.
