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