Plan the Kinetix 5700 Drive System Installation Chapter 2
Regenerative Bus Supply Systems
Mount the 2198-DCBUSCOND-RP312 DC-bus conditioner module on the
far right or far left of any 2198-RPxxx regenerative bus supply system cluster,
depending on the input power configuration.
• A DC-bus conditioner module is required on all extended clusters
• A DC-bus conditioner module is required on the power supply cluster if
the total motor cable length connected to the power supply cluster is
≥400 m (1312 ft)
• A DC-bus conditioner module is required on each cluster of drive
systems with impedance-grounded input power
• When a DC-bus conditioner module is installed and there is no use-case
for installation, the module does not provide any benefit
The following system configurations illustrate the minimum number of
accessory modules required.
