Cat. No.
2198-CAPMOD-2240 Capacitor Module
2198-CAPMOD-DCBUS-IO Extension Module
2198-DCBUSCOND-RP312 DC-bus Conditioner Module
This example includes:
• 1 Bus group
• 2 Drive clusters
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.
8720MC-RPS regenerative power supplies follow the same requirements as
2198-RPxxx regenerative bus supplies for accessory modules needed for
extended clusters. See 8720MC-RPS wiring examples beginning on
Table 21 - Introduction to Kinetix 5700 Accessory Modules
Description
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.
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.
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.
On the following pages (by power supply) are system configurations showing
which accessory modules are required. The examples account for single (power
supply) clusters, extended clusters, maximum system current, the input-power
ground configuration, and total motor-cable length. Also included are
flowcharts to help you determine your accessory module requirements.
