Setting the monitoring
Description
Specify the motor cooling
0: Self-ventilated - with fan on the motor shaft (factory setting)
1: Forced ventilation - with a separately driven fan
2: Self-ventilated and inner cooling (open-circuit cooling)
3: Forced ventilated and inner cooling (open-circuit cooling)
Motor temperature sensor type
0: No sensor (factory setting)
1: PTC (→ p0604)
2: KTY84 (→ p0604, p0605)
4: Temperature switch
Motor temperature alarm threshold (factory setting 130 °C)
Motor temperature fault threshold (Factory setting: 145 °C)
Setting for KTY84 sensor. The parameter has no significance for a PTC sensor.
Motor overtemperature response
Determines the response when the motor temperature reaches the alarm threshold
p0604.
0: Alarm (A07910), but no response of the motor.
1: Alarm (A07910) and reduction of the current limit (factory setting) - this reduces the
motor speed.
2: Fault (F07011) and shutdown.
