Mains voltage low / mains drop-out:
During low mains voltage or a mains drop-out, the FC 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.

Torque rise time in VVC+ (independent of fsw)
Torque rise time in FLUX (for 5 kHz fsw)
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.
