The following table states the direct current values of the dc-link according to the rated power of the motor connected to the inverter The current is calculated on the basis of the following:

-4-pole “standard” motor

-“typical” efficiency for “standard” motors (η Mot)

-the “typical” inverter efficiency is considered equal to 0.97 (η I)

-mains power supply voltage 3 x 380V (conservative value if referred to a rated voltage of 3 x 400V)

-there are two value columns referring to a continuous functioning (class 1) or to a functioning during an overload phase (class 2) (150% for 60 seconds).

The current value in column 1 is calculated as

IDCL = PMot / (hMot x hI x ULN x 1.35)

where for column „Current Dclink IDCL Overload class 2“ it is obtained multiplying by 1.36.
