Extended Regenerative Bus Configuration Example

In this example, two drive clusters in the same cabinet are connected by the
same 458...747V DC bus voltage.
• Kinetix 5700 accessory modules provide connection points for the
DC bus at the end of cluster 1 and the beginning of cluster 2.
• The Kinetix 5700 servo drive system is capable of up to 208 A
DC-bus current. Two parallel accessory modules are needed when
the DC-bus system current exceeds 104 A.
• The DC-bus conditioner module is required when the combined
motor cable length exceeds 400 m (1312 ft). See
Selection
requirements.
