Monitoring functions
Function
The temperature is monitored in two stages. The response temperature for the alarm is 5 °C
below the fault signal threshold. This is oriented to the overload capability of the converter
and results in the drive being shut down. The fault message can be deselected by making
the appropriate parameter settings.
For additional information, please refer to the operating instructions SINAMICS DCM DC
Converter in Chapter, Function descriptions/sensors for ambient and air intake temperature.
