Danfoss VLT FC 101 HVAC Basic Drive

Makes your buildings perform

Danfoss commitment
Danfoss’ longstanding experience in applying drives in HVAC systems has enhanced our ability to design a HVAC Basic drive to the exact needs in simple mass produced applications.

Save energy and CO2 emission
Energy savings through more than 1.5 million VLT® HVAC Drives installed worldwide are estimated at 285 million MWhrs a year. This equals the annual energy consumption of 60 million households and has an impact on the annual CO₂ emissions – a reduction of 180 million tonnes!

A wealth of knowledge
The various applications incorporated within high performance buildings are well understood by Danfoss and as global market leader we have built a wealth of knowledge and developed products and technology to ensure we meet and shape future trends in HVAC.

Danfoss experts with HVAC application knowledge support you in making an efficient system design and investing wisely for documented returns.

Certify your building
Today the prime focus is on overall buildings performance which includes design, construction, efficiency, sustainability and the environmental impact of buildings in the future.
Energy efficient products form part of this overall plan. In many countries around the world the evaluation of high performance buildings falls under the banner LEED. Danfoss drives help you to reduce the energy consumption in your building and to fulfill the highest standards set by these certification bodies.

Ideal for simple fans, pumps, and compressors

User-friendly, distributed intelligence and reduced power consumption are beneficial for fan applications. Basic AHU functions enable the VLT® HVAC Basic Drive to control a wide range of functions. Pump-specific features developed in cooperation with OEMs, contractors and manufacturers around the world.

Fire Override Mode

Fire Override Mode prevents the VLT® HVAC Basic Drive from stopping for self-protecting reasons. In this mode it will continue vital fan operation regardless of control signals, warnings or alarms.
Fire Override Mode helps keep fire escape routes free of smoke and ensures secure and continued operation within applications such as stair-well pressurization, car park exhaust fans, smoke exhaust and essential service functions.
Fire mode is clearly indicated on the display to prevent any confusion. When set, the drive will override self protection and will continue operation despite the possibility of permanent damage in case of over-heating or overload. The vital goal is to keep the motor running even if it means self-destruction.

Skip frequencies
By pressing a few buttons on the Local Control Panel the drive can be set to avoid frequency bands at which connected fans create resonances in the ventilation system. This reduces vibration, noises and wear on equipment.
No load / Broken Belt warning
Many fan applications are still operated by a belt. This function monitors whether the belt is still in use, has ceased operation due to wear and tear.
The built-in maintenance program helps you to ensure belt inspection at regular intervals.

Flying start
The drive can detect speed and direction of a freely spinning fan or pump and “catch” it at the right speed.
This feature prevents violent starts and tear on the equipment.

Sleep Mode
In situations with low or no flow, the drive enters sleep mode to conserve energy. When the pressure falls below the pre-defined setpoint, the drive starts automatically. Compared to continuous operation this method reduces energy costs and equipment wear and tear, extending the lifetime of the application.

Sensorless pump control
Eliminate the need for external pressure transmitters, using this drive.
The drive delivers sensorless pump control, meaning no external pressure transmitter is required.

Constant torque for air compressors
The drive has a dedicated constant torque mode for air compressor applications.

Quiet operation
Direct control of the cooling fan ensures that the drive operates as quietly as possible. The cooling fan adjusts precisely to the load, for optimum efficiency and energy savings.

Simple timer function
There is no need for an external timer, since you can use the integrated timer in the drive. This simple timer function is useful for testing the motor, for example in Fire Mode applications.

Use the motor of your choice
VLT® HVAC Basic Drive FC 101 is equally compatible with induction and permanent magnet (PM) motors for the full power range. There is no need to change out motor type when retrofitting the drive.

More robust when power is unstable
Voltage dips or power interruptions in the grid cause huge problems in your systems. It is reassuring to know that integrated power loss ride-through capability in the drive ensures more stable and robust operation.

Voltage sag immunity
With Semi 47 certification, you can be sure that this drive is performs robustly, whatever the quality of the power supply.

Improved power factor with VLT® Advanced Harmonic Filter AHF 010
Are you using VLT® Advanced Harmonic Filter AHF 010 to mitigate harmonics?
Use the relay output on the drive to control this passive harmonic filter, to achieve a higher power factor at zero load or partial load.

VLT® HVAC Basic Drive

The VLT® HVAC Basic Drive is a competitive drive for simple applications – with basic needs.

Easy commissioning
The Quick Menu wizard makes it easy to set up and operate the drive.
In situations where there is no mains power, use the VLT® Mains-Free Interface tool. It gives you an easy way to configure drives on the production line, and saves time and effort for installation and service technicians.

Maintenance free
Due to a series of self-protecting and monitoring features, the VLT® HVAC Basic Drive is maintenance free, except for general cleaning.
Replacement of internal fans or capacitors is normally not required during lifetime.

Save space
Due to its ultra compact design, the VLT® HVAC Basic Drive is easily mounted inside a HVAC unit or panel, reducing overall enclosure costs.

Built-in mains filters
The standard integrated DC coils comply with EN 61000-3-12 reducing losses in mains and ensuring reliable operation in the whole grid. The DC coils increase the lifespan of the DC link capacitors and they also ensure that the drive can operate motors to their full performance. Integrated DC coils save the cost for adding external filters.

Comparision of limits EN 55011/61800-3

The built-in EMC filter makes the VLT® HVAC Basic Drive conform to the limits for category C1 and C2 according to EN 61800-3, with no additional external components needed, even with long motor cables.

However, more importantly in practice is the compliance with the environmental standard EN 55011, Class B (residential) and Class A1 (industrial). This ensures reliable system operation in full compliance with all requirements for EMC in the operating environments and eliminates required product warnings and restrictions prescribed by the standard, if the drive used does not conform to category C1.

Enclosure protection options

Freedom to change settings prior to installation

VLT® Mains-free Interface
Did you know you can change the settings of the FC 101 drive with no connection to mains power supply? Just connect to a PC using the VLT® Mains-free Interface.
The VLT® Mains-free Interface connects to the PC via a USB 2.0 interface.
A Mini-B USB connector is located at the front, and a standard drive connector is located on the back. Both the VLT® Mains-free Interface and the drive get a supply of current from the USB ports on the PC.

For drive enclosure sizes H1–H5 and I2–I4:
The required current is within the standard capability of a single USB port. Use a single USB type A connector.

For drive enclosure sizes H6–H10 and I6–I8:
More than 500 mA current is required (500 mA is the maximum standard current a USB port can deliver).

Connect to the PC using a double USB type A cable.
The drive obtains the required current via both of the USB ports. The second USB port is marked “Auxiliary power only”.
