90 m (295 ft) x 5 axes = 450 m (1476 ft)
DC-bus conditioner requirements:
• Required on Cluster #1 because cable length exceeds 400 m (1312 ft)
• Required on Cluster #2 because it's an extended cluster

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.
