Line power supply (L1, L2, L3):
Supply voltage
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 adjustable frequency drive's lowest rated supply voltage. Power-up and full torque cannot be
expected at AC line voltage lower than 10% below the adjustable frequency drive's lowest rated supply voltage.
