11.3 General Technical Data - Adjustable Frequency Drive
Line power supply (L1, L2, L3)
Supply voltage
380–480 V +5%
AC line voltage low/line drop-out:
During low AC line voltage or line drop-out, the adjustable frequency drive continues until the intermediate circuit voltage drops
below the minimum stop level, corresponding to 15% below the lowest rated supply voltage. Power-up and full torque cannot be
expected at AC line voltage lower than 10% below the lowest rated supply voltage.
Supply frequency
50/60 Hz ±5%
Max. temporary imbalance between line phases
3.0% of rated supply voltage
True power factor (
λ
)
> 0.98 nominal at rated load
Displacement power factor (cosφ) near unity
(> 0.98)
THiD
< 5%
Switching on input supply L1, L2, L3 (power-ups)
maximum once/2 min.
