Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the drive 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.

Torque characteristics
Starting torque (Constant torque) maximum 110% for 60 s 1)
Starting torque maximum 135% up to 0.5 s 1)
Overload torque (Constant torque) maximum 110% for 60 s 1)
Starting torque (Variable torque) maximum 110% for 60 s 1)
Overload torque (Variable torque) maximum 110% for 60 s
Torque rise time in VVC plus (independent of fsw) 10 ms
1) 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.
