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