Kinetix 5700 Servo Drives
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 for each cluster exceeds 400 m (1312 ft). See the
Kinetix 5700 Servo Drives User Manual, publication 2198-UM002
, for more information on the when accessory modules are required.
