2.6.2. Drive DC Current (DC Link Circuit)

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
- the "typical" inverter efficiency is considered equal to 0.97 (η
- 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).
