14-11 Mains Fault Voltage Level
Default value:
342 V
Setup:
All setups
Data type:
Uint16
This parameter defines the threshold voltage at which the selected function in parameter 14-10 Mains Failure is activated. Based on the
supply quality, consider selecting 90% of the nominal mains as the detection level. For a supply of 380 V, parameter 14-11 Mains Fault
Voltage Level should be set to 342 V. This results in a DC detection level of 462 V (parameter 14-11 Mains Fault Voltage Level x 1.35).
14-12 Response to Mains Imbalance
Default value:
[0] Trip
Setup:
1 setup
Data type:
Uint8
Operation under severe mains imbalance conditions reduces the lifetime of the motor. Conditions are considered severe if the motor is
operated continuously near nominal load (for example, a pump or fan running near full speed).
