Chapter 2 Plan the Kinetix 5700 Drive System Installation
In this flowchart, a 2198-Pxxx DC-bus power supply or 2198-RPxxx
regenerative bus supply supplies DC-bus power to a multi-cluster drive
system. System variables that you need to know include the following:
• The type of AC to DC converter used
• The input-power ground configuration
• The external DC-bus current
• The total motor-cable length of the power supply cluster
Figure 34 - Multi-cluster Drive System
The ‘power supply’ cluster includes the 2198-Pxxx DC-bus power supply
or 2198-RPxxx regenerative bus supply. Extended clusters are part of the
same DC-bus group and connected to the power supply cluster via stud
terminals that are available on accessory modules.
