5 General Specifications
Mains supply (L1, L2, L3):
Supply voltage
380-500 V ±10%
Supply voltage
525-690 V ±10%
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converters continues until the intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the drive'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.
Supply frequency
50/60 Hz ±5%
Max. imbalance temporary between mains phases
3.0 % of rated supply voltage
True Power Factor (λ)
≥ 0.9 nominal at rated load
