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