8.5 Thermal motor protection
● p0609[0...3] allocates the temperature channels for the motor temperatures to signal
● p4100[0...n] = 0 deactivates temperature evaluation.
● r4101[0...3] indicates the actual resistance value of the respective temperature sensor.
● p4102[0/2/4/6] sets the alarm thresholds of the temperature sensors to between -48 °C
● p4102[1/3/5/7] sets the fault thresholds of the temperature sensors to between -48 °C
● p4102[0...7] = 251 °C deactivates the alarm and/or fault message that has been set.
● p4610[0...n] to p4613[0...n], assigns up to four temperature sensors to the motor and
● r4620[0...3] ≠ -200 °C means:
● r4620[0...3] = -200 °C means:
KTY84
● p4100[0...3] = 2 assigns the temperature sensor type KTY84 to a corresponding channel
● r4105[0...3] displays the temperature actual value of the measuring channel involved of
PTC
● p4100[0...3] = 1, sets temperature sensor type PTC to the corresponding channel 1 to 4,
● r4105[0...3] displays the temperature actual value of the temperature evaluation.

and activates the evaluation.
– If the temperature actual value is lower than the rated response temperature, then
r4105[0...3] is set to -50 °C.
– If the temperature actual value is higher than the rated response temperature, then
r4105[0...3] is set to 250 °C.
– If no sensor has been selected or if the temperature actual value is invalid, then
r4105[0...3] is set to -300 °C.
