Protection functions
The frequency inverter offers protective functions against overtemperature and overcurrent
for both the frequency inverter as well as the motor. Further, the frequency inverter protects
itself against an excessively high DC link voltage when the motor is regenerating.
6.6.1
Inverter temperature monitoring
The inverter temperature is essentially defined by the following effects:
● The ambient temperature
● The ohmic losses increasing with the output current
● Switching losses increasing with the pulse frequency
Monitoring types
The inverter monitors its temperature using the following monitoring types:
● I
● Measuring the chip temperature of the Power Module (alarm A05006, fault F30024)
● Measuring the heat sink temperature of the Power Module (alarm A05000, fault F30004)
