Kinetix 5500 System Current Demand Example
In this example, the Kinetix 5500 drive system includes two 2198-H040-ERS
drives, four 2198-H008-ERS drives, and one capacitor module.
Figure 113 - Shared AC/DC Hybrid Configuration
Energy Calculations The Kinetix 5500 servo drives have internal shunt resistors for dissipating
excessive energy. In addition, Bulletin 2097 external shunt resistors and
Bulletin 2198 capacitor modules are available to increase the shared DC bus
capacitance.
Use this table to calculate the total energy absorbing potential (joules) and
determine if a capacitor module or external shunt resistor is needed.
See Motion Analyzer Online, version 7.0 or later, for custom shunt sizing.
