Kinetic Back-up [4]: The frequency converter will keep on running as long as there is energy in the system
due to the moment of inertia produced by the load.
Kinetic Back-up [5]: The frequency converter will ride through on speed as long as the energy is present
from moment of inertia from the load. If the DC voltage goes below par. SP-11 Line Voltage at Input
Fault the frequency converter will perform a trip.

SP-11 Line Voltage at Input Fault
Range: Function:
342. V* [180 - 600 V] This parameter defines the threshold voltage at which the selected function in par. SP-10 Line failure
should be activated.
SP-12 Function at Line Imbalance
Operation under severe main imbalance conditions reduces the lifetime of the motor. Conditions are considered severe if the motor is operated continuously
near nominal load (e.g. a pump or fan running near full speed).
Option: Function:
[0] * Trip Trips the frequency converter
[1] Warning Issues a warning
