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
Switch-on delay p0607 = 0 suppresses fault F07016.
For KTY and "No sensor", temperature as defined in the model.
The relevant rated response temperature in °C depends on the temperature sensor
chosen by the motor manufacturer.
