Running The Inverter In Cavitation Protection Mode - Siemens SINAMICS V20 Series Operating Instructions Manual

5.6.3.14

Running the inverter in cavitation protection mode

Functionality
The cavitation protection will generate a fault / warning when cavitation conditions are
deemed to be present. If the inverter gets no feedback from the pump transducer, it will trip
to stop cavitation damage.

Setting
This parameter enables the cavitation protection function.
= 1: Fault
= 2: Warn
This parameter defines the feedback threshold over which a
fault / warning is triggered, as a percentage (%).
Range: 0.00 ... 200.00 (factory default: 40.00)
This parameter sets the time for which cavitation conditions
have to be present before a fault / warning is triggered.
Range: 0 ... 65000 (factory default: 30)
