Service
Breakdown of Danfoss drives or geared motors only
occur under exceptional circumstances. As downtime
represents lack of production, failures must be located
and defective components replaced quickly.
Danfoss' decentralized products place great
emphasis on addressing these issues. This chapter
also describes measures taken to make Danfoss
decentralized products superior in a service situation.
For detailed information on specific service issues
please consult relevant literature.
Centralized adjustable frequency drives from Danfoss
have pluggable connections to facilitate service using
fast and faultless replacement. The same concept is
used and improved for the decentralized drives.
Plug-and-drive
All the advanced and reliable electronics needed
to ensure your motors act smoothly, responsively
and economically at each command are hidden
inside the box lid and plug into connectors when
mounted onto the bottom section. The bottom section
contains maintenance-free Cage Clamp connectors
and looping facilities for power and fieldbus cables
well protected against dust, hosing and cleaning
agents. Once installed, commissioning and upgrading
can be performed in no time simply by plugging in
another control lid. See the illustration.
Product concept
Since the installation box only contains plugs,
connectors and low density pcb's, it is not likely

to fail. In case of a failure in the electronic part,
just remove the six screws, unplug the electronic
part and plug in a new one.
You only need standard installation material like cable
glands, cables, etc., to commission and service a
Danfoss decentralized drive. Special equipment like
hybrid cables not likely to be held in stock by a standard
supplier of electric installation components is needed.
This provides high flexibility and maximum uptime.
