Description: Selects motor temperature sensor.
No sensor (P0601 = 0)
The motor temperature monitoring will be done based on the estimated value of the thermal motor model.
PTC thermistor (P0601 = 1)
The motor is monitored by the thermal motor model and additionally by the PTC thermistor, thus providing a redun-
dant system for monitoring the motor temperature.
Should the resistance value of 2000 Ohm be exceeded, the inverter trips with fault F0011 (motor overheating).
If the resistance value is below 10 Ohm, then the fault F0015 (motor temperature signal lost) is output.
This protects the motor from overheating and also from a sensor wire breakage.
KTY84 (P0601 = 2)
The temperature of the sensor (thus that of the motor windings) is written to parameter r0035. This motor tempera-
ture is then additionally calculated via the thermal motor model.
If the electric circuit to the KTY84 sensor is open or if a short circuit occurs, fault F0015 (motor temperature signal
lost) is generated.
Values: 0: No sensor
1: PTC thermistor
2: KTY84
Dependency: The motor overheating warning threshold needs to be assigned with parameter P0604 (the factory setting is 130
°C). This warning threshold depends on the motor's thermal class.
The motor overheating disturbance threshold is automatically set by the inverter at 10 % higher than the tempera-
ture declared in parameter P0604. In parameter P0610 is set, how the inverter reacts on overtemperature.
Description: Enters warning threshold for motor temperature protection.
The trip temperature defined is always 10 % higher than the warning threshold P0604. When actual motor temper-
ature exeeds trip temperature then inverter trips as defined in P0610.
Dependency: This value should be at least 40°C higher than the motor ambient temperature P0625.
Note: Default value depends on P0300 (select motor type).
