Capacitors
The drive intermediate DC circuit employs several electrolytic capacitors. Their
lifespan depends on the operating time of the drive, loading and ambient
temperature. Capacitor life can be prolonged by lowering the ambient temperature.
Capacitor failure is usually followed by damage to the drive and an input cable fuse
failure, or a fault trip. Contact the manufacturer if capacitor failure is suspected.
Replacements are available from the manufacturer. Do not use other than specified
spare parts.
Reforming the capacitors
The capacitors must be reformed if the drive has not been powered (either in storage
or unused) for a year or more. See section
Type designation label
on page
35
for how
to find out the manufacturing date from the serial number.
For information on reforming the capacitors, see Converter module capacitor
reforming instructions (3BFE64059629 [English]), available on the Internet (go to
