7.3 Mains Supply
Mains supply (L1, L2, L3)
Supply voltage
380–500 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.
