Appendix C Size Multi-axis Shared-bus Configurations
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.
Table 84 - Energy Absorbing Potential
Refer to Motion Analyzer software, version 7.0 or later, for custom shunt
sizing.
