Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the frequency converter's lowest rated supply voltage.
Power-up and full torque cannot be expected at mains voltage lower than 10% below the frequency converter's lowest rated
supply voltage.

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.
3) Special customer versions with output frequency 0-1000 Hz are available.
