to +10%
1) The frequency converter can run at -25% input voltage with reduced performance. The maximum output power of the
frequency converter is 75% in case of -25% input voltage and 85% in case of -15% input voltage.
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter 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.
The unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 480 V maximum.

Percentage relates to the nominal torque.
2)
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.
