Kinetix 6000 E09: BusUndervoltage Fault (Bus Undervoltage)
Also shown as: Shown as E09 on the seven-segment display
What E09 means
The DC bus voltage fell below the minimum while three-phase power was present.
Symptoms
Fault under load, on supply dips, or when an axis is enabled on a follower rail.
Is it repairable?
Yes, when the IAM converter section is the cause.
Common causes
- Low or missing supply phase
- Supply dips
- Converter or bus capacitor problems in the IAM
Safe checks
- 1Measure all three supply phases under load
- 2Check fuses and the main contactor
Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.
