DC Common Bus Applications Appendix C
Calculate Additional Bus
Capacitance
Additional bus capacitance is the sum of all follower IAM, AM, and IPIM
module capacitance values for your Bulletin 2094 common-bus modules.
Specifically, this includes the capacitance values for each of these modules:
• Each follower IAM (converter and inverter) module
• Each AM module on the follower IAM module power rail
• Each IPIM module on the follower IAM module power rail
If you are using Kinetix 6200 (sercos) drives or Kinetix 6500 (integrated
motion on EtherNet/IP) drives, calculate additional bus capacitance in this
appendix and enter the value in Module Properties>Power tab>Bus
Capacitance.
In the example on page 270
, the value is 790 µF.

capacitance for your Bulletin 2094 common-bus application.
