10.2 General Technical Data
Mains supply
Supply Terminals L1, L2, L3
Supply voltage 200-240 V ±10%
Supply voltage 380-480 V/525-600 V ±10%
Supply voltage 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 frequency converter'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
Displacement Power Factor (cos ϕ) near unity (>
0.98)
Switching on input supply L1, L2, L3 (power-ups) ≤ 7.5 kW maximum 2
times/min.
Switching on input supply L1, L2, L3 (power-ups) 11-75 kW maximum 1 time/min.
Switching on input supply L1, L2, L3 (power-ups) ≥ 90 kW maximum 1
time/2 min.

The torque response time depends on application and load but as a general rule, the torque step from 0 to reference is 4-5 x
torque rise time.
