Supposing that the same ratings as the motor drive apply to the regenerative drive being used, the loss of a
0020 4T drive is 0.35kW (see “4T Class Regenerative Drive” tables).
As a result, the continuous power of the regenerative drive should be the following:
Pconrgn= 16.5 + 0.35 + 0.35 =17.2kW
Polrgn= overloaded motor drive overloaded regenerative drive losses
Polmot=1.73*Vmot*Ilim* power factor
Polmot=20.7kW
The drive losses are to be compared to the overload current:
Polrgn=20.7+0.35* Ilim/Imot+0.35* Ilim/Imot=21.54kW
From the 4T Class Regenerative Drive tables, the continuous power and the overload power of a SINUS
PENTA 0020 4T regenerative drive with 400VAC power supply is 18.3kW and 22.1kW respectively; as a
result, the SINUS PENTA 0020 4T can be used.
The same result is given in the Light Applications (Overload Up To 120%) table, where a 15kW motor with a
rated voltage ranging from 380V to 415V connected to a SINUS PENTA 0020 4T is coupled to a
regenerative SINUS PENTA 0020 4T.
