Capacitors
The drive intermediate circuit employs several electrolytic capacitors. Their lifespan
is at least 90 000 hours depending on the operating time of the 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
damage to the unit and an input cable fuse failure, or a fault trip. Contact ABB if
capacitor failure is suspected. Replacements 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
ACS 600/800
Capacitor Reforming Guide
[code: 64059629 (English)].
Replacing the capacitor pack (R7)
Replace the capacitor pack as described in section
