Parameters for detecting the motor temperature via a temperature sensor
Description
Specify the motor cooling
0: Self-ventilated - with fan on the motor shaft (IC410* or IC411*) - (factory setting)
1: Forced ventilation - with a separately driven fan (IC416*)
2: Self-ventilated and inner cooling* (open-circuit air cooled)
3: Forced ventilated and inner cooling* (open-circuit air cooled)
Motor temperature sensor type
0: No sensor (factory setting)
1: PTC thermistor (→ P0604)
2: KTY84 (→ P0604)
4: ThermoClick sensor
Motor temperature alarm threshold (factory setting 130 °C)
The alarm threshold is the value at which the inverter is either shut down or I
reduced (P0610)
Motor temperature fault threshold (Factory setting: 145 °C)
Motor overtemperature response
Determines the response when the motor temperature reaches the alarm threshold.
0: No motor response, only an alarm
1: Alarm and reduction of I
reduces the output speed
2: Fault message and shutdown (F07011)
Current limit (input in A)
Terminal no.
