4.4 DC bus paralleling
DC bus paralleling using standard cable / busbars is supported by all frame sizes.
On frame sizes 3, 4, 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 return energy from a drive which is being overhauled by the load to a second
motoring drive.
Figure 4-15 DC bus paralleling (size 3 shown)
There are limitations to the combinations of drives which can be used in this configuration.
For application data, contact the supplier of the drive.
The DC bus paralleling kit is not supplied with the drive but available to order.
