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” table).
As a result, the continuous power of the regenerative drive should be the following:
Pconrgn= 16.6 + 0.35 + 0.35 =17.3 kW
Polrgn= overloaded motor drive loss + overloaded regenerative drive loss
Polmot=1.73*Vmot*Ilim*cosphimot
→
Polmot=20.7kW
The drive loss is 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 table, 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%) 380-500Vac Power Supply table,
where a 15kW motor with a rated voltage ranging from 380V to 415V connected to a SINUS K/PENTA 0020
4T is coupled to a regenerative SINUS PENTA 0020 4T.
