Setting parameters for the temperature monitoring
Parameter
Description
p0335
Specify the motor cooling
0: Natural cooling - with fan on the motor shaft (factory setting)
1: Forced ventilation - with a separately driven fan
2: Liquid cooling
128: No fan
p0601
Motor-temperature sensor type
0: No sensor (factory setting)
1: PTC (→ p0604)
2: KTY84 (→ p0604, p0605)
4: Temperature switch
p0604
Motor temperature alarm threshold (factory setting 130° C)
p0605
Motor temperature fault threshold
(factory setting 145° C)
Setting for KTY84 sensor. The parameter has no significance for a PTC sensor.
p0610
Motor overtemperature response
(factory setting: 12)
Determines the behavior as soon as the motor temperature reaches the warning
threshold p0604.
0: Alarm (A07910), no fault.
1: Alarm (A07910); the converter reduces the current limit and starts the timer.
Shutdown with fault (F07011).
2: Alarm (A07910); the converter starts the timer. Shutdown with fault (F07011).
12: As for 2, but the converter considers the last shutdown temperature to calculate
the motor temperature.
