4.2.3 Input inductor calculation
To calculate the inductance required (at Y %), use the following equation:
Where:
I = drive rated input current (A)
L = inductance (H)
f = supply frequency (Hz)
V = voltage between lines
4.3 Supplying the drive with DC
All drive sizes have the option to be powered from an external DC power supply. Refer to section
4.1 Power and ground connections on page 49 to identify the location of DC supply connections.
4.4 DC bus paralleling
DC bus paralleling using standard cable / busbars is supported by all frame sizes.
On frame sizes 5 and 6, terminal and enclosure design enables the DC bus of a number of drives to
be connected together using pre-made busbars. The diagram below shows how the busbar links
connect the DC bus of several drives together.
The connecting of the DC bus between several drives is typically used to:
1. Return energy from a drive which is being overhauled by the load to a second motoring drive.
2. Allow the use of one braking resistor to dissipate regenerative energy from several drives.
