FC-301 and FC-302 general features

The modular VLT Automation Drive



In our previous discussions we introduced already the available Variable Frequency Drives (VFD) models from Danfoss and we also referred already to the corresponding product brochures and further supporting literatures such as the manuals or programming guides which all the available parameters and its descriptions.

Basically we have the FC-51, better known as the VLT Micro as a low priced, yet though really very powerful entrance level unit for basic applications under regular conditions, our VLT-2800 series, a real robust veteran is preferred for regular V/Hz applications by some of our customers and then we have our most versatile FC-300 series which we also call the Automation Drive and we do that for good reasons because here we can really say:


Nothing is impossible!


The modular VLT Automation Drives with its FC-301 and FC-302 versions are truly a one fits all solution because there is nothing indeed these models could not handle. It is the successor of the famous VLT-5000 Drive and one real example of a product which very well may exceed some of your expectations and we certainly do hope to amaze you in this blog category.

Danfoss Drives received the Frost & Sullivan Award for product innovation 2006 for the unique VLT-Automation Drive or FC-300 series!

Let us begin with a quick overview of some initial features such as for example:


The enclosure:


The Drive meets requirements for enclosure class IP20 on the important chassis. Optional IP21 or Nema 1 (additional drip water protection), IP54 and IP55, Nema 12 (water and dust resistant from all directions) and even IP66, Nema 4X (protection against pressurized water and complete dust tight) are available!


The cold plate technology:


The Drives up to a size of 15KW (20HP) are built on a rock-solid aluminum base that is integrated with the back panel. This provides high mechanical stability, efficient cooling and the option of cold plate operation.


The display options:


Danfoss Drives removable and hot pluggable local control Panel (LCP) is now available in 28 languages. Six of these are built-in (including Chinese) two of the languages can be changed by the user.

The info button makes the printed manual virtually redundant, so the maintenance works could be done quickly because the Drive literally speaks to you.

The graphical display unit was actually designed by a previous Nokia engineer which makes it really so easy to scroll through the menus, not too much different to a cell phone!

Users have been involved throughout the development to ensure great functionality and performance. The user group has significantly influenced design and function of the local control panel (LCP).

The automatic motor adaption (AMA), quick set-up menu and large graphic display makes commissioning and operation a real breeze. It is your choice of numeric display, graphical display or blind cover.


The modular construction and ease of maintenance:


All components are easily accessible from the front of the Drive, allowing for ease of maintenance and side by side monitoring of Drives. The VFD is designed with a modular approach, allowing for the easy replacement of modular sub-assemblies.


The fieldbus option:


Options for bus communication such as for example Profibus, DPV1, Devicenet, CANopen, Ethernet/IP, etc, etc, etc and synchronization, user programs, etc, etc, etc are delivered ready to go.


The RFI filters:


Built-in RFI filters on both inputs (for complete immunity) and outputs (for emission elimination) even for long motor cables are fully compliant to the IEC 81800-3 and EN EN55011 standards.


The application options:


Available are general purpose I/O, CI encoder, resolver, relay options, ATEX and safe interface.


The DC coil:


The renowned DC coil ensures very low harmonic disturbance of the power supply and the filtering actions on both input and output again are in accordance with IEC 1000-3-2. Compact design means no need for external modules, something other manufacturers have yet to match.


The programmable options:


Available here are free programmable option MCO-305, option for synchronization, or positioning, cam control, center winding and many more.


The back channel cooling:


A unique design uses a ducted back channel to pass cooling-air over heat sinks. This allows 85% of the heat losses to be exhausted directly outside of the enclosure with minimal air passing through the electronics area.

This dramatically reduces temperature rise and contamination of the electronic components such as for example dust which is really a killer for electronics in general but here in the Philippines very much in particular.

This is so because we are living and working here in a tropical environment which is not only hot but also humid, even more so in specific areas like for example steaming departments and such alike.

Any accumulation of dust covers would not only heat up the electronics but the humidity could turn this contamination even conductive, especially so during an intended or unintended standby mode or downtime because this would cool the unit down and some specific areas would even catalyze the development of additional condense water, so dust is a really a very potential killer, especially so here in the Philippines and this special feature helps improving the reliability plus it also prolongs its own life.

There is also an IP54 rated seal in between the back channel cooling duct and the electronics area of the Drive.


The hot pluggable LCP:


The local control panel (LCP) can be plugged in or else also unplugged during operation. Settings are easily transferred via the control panel from one Drive to another or also from a PC with MCT-10 set-up software installed. This reduces very obviously the commissioning time when programming same or similar applications for example on different lines.


The input mains option:


Various input plate configurations are available including fuses, mains switch (disconnect) or RFI filters. Input plates are field adaptable if options need to be added after the installation.


The corrosive resistance:


As an option, the back channel cooling duct work and heat sinks can be ordered with corrosion protection for installations in harsh environments for example near the ocean.


The control terminals:


Specially developed spring-loaded cage clamps enhance reliability and facilitate easy commissioning and service.


The high ambient temperature:


The Drive and all its ratings are designed to give its maximum outputs at an ambient temperature of up to 50 degrees Celsius (122 degrees Fahrenheit), even at IP55 ratings, another feature unmatched by many others.


The removable fan:


Like most of the elements, the fan can be quickly removed and remounted again for easy cleaning.


The safety:


The VLT Automation Drive FC-302 comes standard with the safe stop functionality. The solution is approved by authorities for category 3 installations in accordance with EN 954-1 and SIL2/IEC 61508. This feature prevents the Drive from starting unintended. Enhanced safety features are available as options.


The control voltage supply:


24 Volts supply keeps the VLT Automation Drive logic “alive” when the AC mains are removed.


The conformal coating:


The electronic components are standard coated as per IEC 60721-3-3, class 3C2. For harsh and aggressive environments an upgraded coating as per IEC 60721-3-3, class 3C3 is also available.


Closure for this post:


In earlier blog entries we did include already quite a variety of downloadable links to brochures, catalogues, manuals, overviews, presentations, videos, etc, etc, etc but here we decided to leave the sheets more clean in order not to spoil the message.

However, we would still highly recommend to read as well our
