4.2 General Specifications
Mains supply (L1, L2, L3)
Supply terminals
L1, L2, L3
Supply voltage
380–480 V:-15% (-25%)
1)
to +10%
1) The frequency converter can run at -25% input voltage with reduced performance. The maximum output power of the
frequency converter is 75% in case of -25% input voltage and 85% in case of -15% input voltage.
Full torque cannot be expected at mains voltage lower than 10% below the frequency converter'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.
