AC line voltage low/line drop-out:
During low AC line voltage or a line drop-out, the adjustable frequency drive continues until the intermediate circuit voltage
drops below the minimum stop level which corresponds typically to 15% below the lowest rated supply voltage of the adjustable
frequency drive. Power-up and full torque cannot be expected at AC line voltage lower than 10% below the lowest rated supply
voltage of the adjustable frequency drive.
Supply frequency
50/60 Hz +4/-6%
The adjustable frequency drive power supply is tested in accordance with IEC61000-4-28, 50 Hz +4/-6%.
