AC line voltage low/voltage drop-out: During low AC 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
linevoltage lower than 10% below the adjustable frequency drive’s lowest rated supply
voltage.
Supply frequency 50/60 Hz ±5%
Maximum temporary imbalance between line phases 3.0% of rated supply voltage
