11.4.2 Process Protection [420]
Submenu with settings regarding protection functions for
the AC drive and the motor.
Low Voltage Override [421]
If a dip in the mains supply occurs and the low voltage
override function is enabled, the AC drive will automatically
decrease the motor speed to keep control of the application
and prevent an under voltage trip until the input voltage
rises again. Therefore the rotating energy in the motor/load
is used to keep the DC link voltage level at the override level,
for as long as possible or until the motor comes to a
standstill. This is dependent on the inertia of the motor/load
combination and the load of the motor at the time the dip
occurs, see Fig. 108.
