Size Multi-axis Shared-bus Configurations
In this example, 2 drive clusters in the same cabinet are connected by the same
450…750V DC-bus voltage. Kinetix 5700 capacitor modules provide
connection points for the DC bus at the end of cluster 1 and the beginning of
cluster 2. The extension module is needed only when the DC-bus system
current exceeds 100 A, and can support up to 200 A maximum external DC-
bus current.
