8.2 General Specifications
Mains supply (L1, L2, L3):
Supply voltage 200-240 V ±10% 380-480 V ±10% 525-600 V ±10% 525-690 V ±10%
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.
Supply frequency 50/60 Hz ±5%
Max. imbalance temporary between mains phases 3.0 % of rated supply voltage
True Power Factor () ≥ 0.9 nominal at rated load
Displacement Power Factor (cos) near unity (> 0.98)
Switching on input supply L1, L2, L3 (power-ups) ≤ enclosure type A maximum twice/min.
Switching on input supply L1, L2, L3 (power-ups) ≥ enclosure type B, C maximum once/min.
Switching on input supply L1, L2, L3 (power-ups) ≥ enclosure type D, E, F maximum once/2 min.
