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.

1) Percentage relates to the nominal torque.
2) The torque response time depends on application and load but as a general rule, the torque step from 0 to reference is 4–5 x
torque rise time.
