7.3 Mains Supply
Mains supply
Supply terminals (6-pulse) L1, L2, L3
Supply terminals (12-pulse) L1-1, L2-1, L3-1, L1-2, L2-2, L3-2
Supply voltage 380–480 V ±10%, 525–690 V ±10%
Mains voltage low/mains voltage drop-out:
During low mains voltage or a mains drop-out, the drive continues until the DC-link voltage drops below the minimum stop
level, which corresponds typically to 15% below the lowest rated supply voltage of the drive. Power-up and full torque cannot be
expected at mains voltage lower than 10% below the lowest rated supply voltage of the drive.
Supply frequency 50/60 Hz ±5%
Maximum imbalance temporary between mains phases 3.0% of rated supply voltage
1)
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) Maximum 1 time/2 minute
Environment according to EN60664-1 Overvoltage category III/pollution degree 2
The drive is suitable for use on a circuit capable of delivering up to 100 kA short-circuit current rating (SCCR) at 480/600 V.
