Rockwell Automation Allen-Bradley Kinetix 5700 - Extended Regenerative Bus Configuration Example

26 Rockwell Automation Publication 2198-UM002L-EN-P - October 2021
Chapter 1 Start
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 Accessory Module Selection
on
page 56
for more information on accessory module requirements.
