Kinetic back-up:
The frequency converter will perform a Kinetic back-up. If par. 2-10 is [0] or AC brake [2]
follow the Over Voltage Ramping. If par. 2-10 is [1]
Quick stop ramp time.
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. 14-11 the frequency converter will perform
a trip.
Function:
This parameter defines the threshold voltage at which the selected function in par. 14-10 should be activated.
Function:
When a severe mains imbalance is detected:
Trip
Select [0] to trip the frequency converter;
Warning
Select [1] to issue a warning; or
Disabled
Select [2] for no action.
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).
