Kinetix 5700 Accessory Modules
The requirements for when to use accessory modules vary depending on whether your system is powered by the 2198-Pxxx DC-bus power
supply or 2198-RPxxx regenerative bus supply.
Accessory Flow Chart
In this flowchart, a 2198-Pxxx DC-bus power supply or 2198-RPxxx regenerative bus supply supplies DC-bus power to a mixed-architecture
common-bus drive system.
System variables that you need to know include the following:
• The type of AC to DC converter used
• The external DC-bus current
Accessory Module
Cat. No.
Accessory Module Description
2198-CAPMOD-2240 Capacitor Module
Use for energy storage and to extend the DC-bus voltage to another inverter cluster. Modules are zero-stacked
with servo drives and use the shared-bus connection system to extend the external DC-bus voltage in
applications up to 104 A. Can parallel with itself or with another accessory module for up to 208 A.
2198-CAPMOD-DCBUS-IO Extension Module
The extension module, paired with a capacitor module or DC-bus conditioner module, is used to extend the
DC-bus voltage to another inverter cluster in systems with ≥104 A current and up to 208 A.
2198-DCBUSCOND-RP312 DC-bus Conditioner Module
Decreases the voltage stress on insulation components in an inverter system with long cable lengths and used
to extend the DC-bus voltage to another inverter cluster. Modules are zero-stacked with servo drives and use
the shared-bus connection system to extend the external DC-bus voltage in applications up to 104 A. Can
parallel with itself or with another accessory module for applications up to 208 A.
The power supply cluster includes the 2198-Pxxx DC-bus power supply or 2198-RPxxx regenerative bus supply.
