Customer ServiceCapacitor trip devices are commonly used in switchgear to provide trip circuit power and to provide voltage sag ride through capability for digital relays. CTD is not commonly used for closing applications as it is expected that the normal control power will be available when closing is desired.
Comparing undervoltage trip thresholds with the nominal DC bus voltage we can see that the undervoltage trip settings for most drives is around 60% of nominal DC bus voltage. The undervoltage threshold at which fault is triggered will vary between manufacturers.
The Undervoltage trip threshold is based on the programmed input voltage. For example, if the input voltage is 460V and the drive voltage parameter is programmed as 480V, the undervoltage trip threshold will be higher than if it was programmed for 460V.

Yes, any dip in DC bus voltage can lead to a DC link undervoltage fault event. This guide helps troubleshoot VFD problems with undervoltage fault codes. The ideal DC bus voltage for a 3-phase VFD under idle conditions should be approximately the square root of 2 multiplied by the AC RMS voltage.
