Capacitors

The drive intermediate circuit employs several electrolytic capacitors. The lifespan
depends on drive loading and ambient temperature. Capacitor life can be prolonged
by lowering the ambient temperature.
It is not possible to predict a capacitor failure. Capacitor failure is usually followed
by a mains fuse failure or a fault trip. Contact ABB if capacitor failure is suspected.
Replacements for frame size R4 and up are available from ABB. Do not use other than
ABB specified spare parts.

Reforming


Reform (re-age) spare part capacitors once a year according to
with electrolytic DC capacitors in the DC link, Capacitor reforming instructions
(3BFE64059629 [English]).
