Mains voltage low/mains dropout:
During low mains voltage or a mains dropout, the frequency converter continues until the DC-link voltage drops below the
minimum stop level, which corresponds typically to 15% below the frequency converter's lowest rated supply voltage. Power-up
and full torque cannot be expected at mains voltage lower than 10% below the frequency converter's lowest rated supply
voltage.
