5.6.3.15 Running the converter in cavitation protection mode
Functionality
Cavitation occurs when air bubbles are generated around the surface of the impeller,
resulting in pump damage, unexpected noise, and decreased flow or pressure of the pipe
system. The cavitation protection will generate a fault/warning when cavitation conditions are
deemed to be present. If the converter gets no feedback from the pump transducer, it will trip
to prevent cavitation damage. This function saves the maintenance efforts and extends the
lifetime expectancy.
Setting parameters
P2360[0...2] Enable cavitation protection This parameter enables the cavitation protection function.
= 1: Fault
P2361[0...2] Cavitation threshold [%] This parameter defines the feedback threshold over which a fault/warning is
triggered, as a percentage (%).
Range: 0.00 to 200.00 (factory default: 40.00)
P2362[0...2] Cavitation protection time [s] This parameter sets the time for which cavitation conditions have to be pre-
sent before a fault/warning is triggered.
Range: 0 to 65000 (factory default: 30)
