Capacitors
The drive intermediate circuit employs several electrolytic capacitors. Their lifespan
depends on the operating time of the drive, loading and ambient temperature. The
lifespan of the capacitor can be prolonged by lowering the ambient temperature.
It is not possible to predict a capacitor failure. The capacitor failure is usually
followed by damage to the unit and an input cable fuse failure, or a fault trip. Contact
ABB if a capacitor failure is suspected. Replacements are available from ABB. Do
not use other than ABB specified spare parts.
Reforming the capacitors
The capacitors must be reformed if the drive module has been stored for a year or
more. See page
for information on finding out the manufacturing date. For the
reforming instructions, see
Converter modules with electrolytic DC capacitors in the
DC link, capacitor reforming instructions
(3BFE64059629 [English]).
Memory unit
When a drive module is replaced, the parameter settings can be retained by
transferring the memory unit from the defective drive module to the new module. The
memory unit is located in the JCU control unit, see page
WARNING!
Do not remove or insert a memory unit when the drive module is
powered.
After power-up, the drive will scan the memory unit. If a different application program
or different parameter settings are detected, they are copied to the drive. This may
take several minutes.
