Kinetix 5700 Servo Drives
Extended DC-bus Configuration Example
In this example, two drive clusters in the same cabinet are connected by the same 276…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 accessory modules are needed when the DC-bus system current exceeds 104 A. See the
Kinetix 5700 Servo Drives User Manual, publication 2198-UM002
, for more information on the when accessory modules are required.
