Hi hoping someone can assist me with current issue I am experiencing with an ABB drive.
Problem I’m experiencing is a ABB drive supply a large fan cannot reach 100% speed without tripping on supply loss with no fault indication.
I have 2 drives operating exact same spec fans and only get issues with one drive when it has been off for extended periods no issues with other drive.
When ramping from 98-100% drive will trip, I have tried everything code traps, service support ABB, changed hardware. Annoying thing is sometimes drive flukes it and will reach 100% and as drive is running non stop once it hits 100% it stays that way until next maintenance outage! I’m currently running drive at 98% after maintenance period.
I am at a loss and if any experts could assist it would be hugely appreciated
