Danfoss Drives

Low Voltage
Danfoss Drives provides low voltage VLT AC drives in a power range up to 5.3 MW. With a wide variety of built-in functionality, they improve energy efficiency, cut costs and optimize the productivity of your processes.

Our dedicated drives bring optimized process control for specialized applications in specific industries.

VLT® AutomationDrive FC 301 / FC 302

The VLT® AutomationDrive is designed for variable speed control of all asynchronous motors and permanent magnet motors. It comes in a standard version (FC 301) and an advanced high dynamic version (FC 302) with additional functionalities. It helps save energy, increase flexibility, reduce costs related to spare parts and servicing, and optimize process control on any industrial machine or production line.

The VLT AutomationDrive is built on a flexible, modular design concept to provide versatile control. Its robust construction ensures maximum uptime. It comes equipped with a wide range of standard industry features which can be expanded with ‘plug-and-play’ options. The user-friendly graphical control panel ensures the drive is easy to set up and operate saving commissioning and operating costs.

Enclosures are available up to IP 66 (depending on the model). Integrated DC chokes and RFI filters in all models protect installations by minimizing harmonic distortion and electromagnetic interference.

The VLT AutomationDrive can also be used with applications that need to perform high-precision positioning and synchronization operations. The Integrated Motion Controller (IMC) functionality is now configurable in the drive’s software. No additional modules or hardware are necessary.

All drives are fully tested already at the factory. They require very little maintenance and provide a fast return on investment.

12-pulse drive

  • 3 x 380-690 V…250-1200 kW

Features and benefits

  • There’s less need for cooling or oversizing as the ambient temperature is 50°C without derating
  • The need for PLC capacity is reduced thanks to Smart Logic Control
  • Low lifetime costs are ensured as the drive is highly resistant to wear and tear
  • The lifetime of electronics is prolonged due to back-channel cooling for frames D, E and F
  • Commissioning and upgrades are easy due to plug-in technology
  • High-precision position and synchronization thanks to availability of Integrated Motion Controller throughout the entire product range
  • Features such as intelligent heat management, Safe stop and Safe Torque Off ensure safe and energy-efficient operation of the drive

Applications

Conveyors, positioning and synchronizing, cranes, mixers, centrifuges and palletizing and packaging machinery.

 

Decentral Drives

Decentral drives can be mounted close to motors. This eliminates the need for a designated control room and complex cabling which dramatically reduces design and installation costs.

VLT® Decentral Drive FCD 302

Designed for simplicity and robustness, the VLT® Decentral Drive FCD 302 is a user-friendly product with high performance and a strong protection degree.

A decentral-drive solution eliminates the need for space-consuming control cabinets. And, with the drives placed near the motor, there is no need for long-screened motor cables.

With the VLT Decentral Drive FCD 302, all the options are built into the unit reducing the number of boxes to be mounted, and the connections and terminations in the installation. As a result, labor costs and the risks of failure are dramatically reduced.

Supply voltages and power range 

  • 3 x 380-480 V…0.37-3 kW

Features and benefits

  • Installation is flexible as the drive adapts to any brand of motor
  • Servicing is fast and easy due to the pluggable twin-part design
  • Cleaning is easy thanks to the drive’s smooth surface
  • Cable savings are possible as a result of the integrated power and fieldbus looping terminals
  • Direct connection to a PC is possible thanks to the integrated USB port
  • The need for PLC capacity is reduced due to the built-in smart logic controller

Applications

With its IP 66 enclosure, the VLT Decentral Drive FCD 302 is ideal for conveyor applications, sorter systems, installations in wash-down areas or widely distributed applications with a large number of drives in, for example, the food and beverage and materials-handling industries.

 

Soft Starters

Danfoss Drives soft starters are used to temporarily reduce the load and torque by limiting electric current surge of an AC motor during start-up. This reduces both mechanical and electrodynamic stresses to extend the lifetime of the system.

VLT® Soft Starter MCD 500

Effectively protect motors while saving energy.

A comprehensive solution for soft starting and stopping of three-phase asynchronous motors that increases uptime and reduces maintenance requirements.

By integrating soft starters with AC motors, you can save energy, space and costs and increase the lifetime of your system by reducing wear on motors, power cables and the electrical distribution system. And there is no need to consider filters and screened cables, as soft starters generate zero harmonics.

Supply voltages and power range

  • 200-690 V…7.5-850 kW

Features and benefts

  • Programming is quick and easy thanks to three menu systems (Quick Menu, Application Setup and Main Menu), a four-line graphical display and a logic keypad
  • The best starting and stopping profile for the application is chosen using Adaptive Acceleration Control
  • Motors can be used to their full potential without risk of damage from overloading due to second-order thermal model
  • Installation costs are lower and there is less stress on the motor thanks to DC injection braking distributed evenly over three phases
  • Space can be saved, cabling costs reduced and retrofitting made easier as a result of adjustable bus bars which allow for both top and bottom entry

Applications

Centrifugal pumps and fans, conveyors, crushers, grinders, mixers, compressors, centrifuges, mills and saws.
