Total bus capacitance is the sum of all capacitance values for your
Kinetix 6000 common bus modules. Specifically, this includes the
capacitance values for each of these modules.
• Leader IAM (converter and inverter)
• Each AM and SM (if present) on the leader IAM power rail
• Each follower IAM (converter and inverter)
• Each AM on the follower IAM power rails
Refer to Kinetix 6000 Capacitance Values on page 233 for IAM/AM/SM
capacitance values.
When total bus capacitance exceeds the leader IAM maximum
IMPORTANT
value, the IAM fault status LED indicator displays error code
E90 (pre-charge time-out fault) and the drive is disabled.

If your total bus capacitance value exceeds the value in the
IMPORTANT
table above, you must increase the size of the leader IAM or
decrease the total bus capacitance by removing axis modules.
Additional bus capacitance is the sum of all follower IAM and AM
capacitance values for your Kinetix 6000 common bus modules.
Specifically, this includes the capacitance values for each of these
modules.
• Each follower IAM (converter and inverter)
• Each AM on the follower IAM power rails
Enter the additional bus capacitance values in Step 6 of Setting the
Additional Bus Capacitance Parameter.
