Description
Motor-cooling method (factory setting: 0)
0: Natural cooling - with fan on the motor shaft
1: Forced ventilation - with a separately driven fan
2: Liquid cooling
128: No fan
Motor temperature sensor type
0: No sensor (factory setting)
1: PTC
2: KTY84
4: Temperature switch
6: PT1000
Mot_temp_mod 2 / sensor alarm threshold (factory setting 130° C)
For monitoring the motor temperature with KTY84/PT1000.
Mot_temp_mod 1/2 / sensor threshold and temperature value (factory setting: 145° C)
For monitoring the motor temperature with KTY84/PT1000.
Motor overtemperature response (factory setting: 12)
Determines the inverter behavior when the motor temperature reaches the alarm
threshold p0604.
0: Alarm A07910, no fault.
1: Alarm A07910 and fault F07011. The inverter reduces its current limit.
2: Alarm A07910 and fault F07011.
12: Alarm A07910 and fault F07011. For use of the thermal motor model in parallel to
the temperature sensor: After switching off the supply voltage, the inverter saves the
most-recently calculated difference to the ambient air temperature. After switching the
supply voltage on again, the thermal motor model starts with 90% of the previously
saved difference temperature.
Current limit [A]
Motor temperature sensor configuration
.00 0 signal: Enable PTC short-circuit monitoring
1 signal: Disable PTC short-circuit monitoring
