VLT® AutomationDrive FC 301 / FC 302

Versatile, reliable and consistently awesome

Built to last, this robust drive operates effectively and reliably even with the most demanding applications and in the most challenging environments.

VLT® AutomationDrive takes full advantage of all that the new digital age has to offer to ensure it completely fulfills the requirements of your applications and optimizes your processes throughout the entire lifecycle.

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.

Integrated Motion Controller

High-precision positioning and synchronization with reduced costs and system complexity

To optimize performance, many applications across all industry sectors have a need for precise positioning and synchronization. These applications include:

• rotary tables 
• packaging machines
• labelling machines 
• conveyors 
• extruders
• palletizers

To date, positioning and synchronization operations have been performed using servo drives. However, servo equipment is expensive; it is difficult to commission and requires additional cabling. And, as servo drives do not work with open loop control systems, there is a high failure rate. Many applications do not require the high dynamic performance offered by a servo drive. An alternative was to use an AC drive. But, until now, an additional internal or external module or an encoder on the motor was required.

Danfoss Drives has developed an innovative alternative to servo control. The Integrated Motion Controller (IMC) is functionality that enables an AC drive to perform high-precision positioning and synchronization operations without the need for additional modules or hardware. IMC is now configurable in the software of the VLT® AutomationDrive FC 302.

IMC has many advantages. It works with all conventional motor technologies, with closed loop or open loop control, and offers sensorless homing with torque detection. Drives are adapted to the applications through simple parameterization. This means that knowledge of servo technology or programming languages is not required. As no encoder or additional cables are needed, engineering, installation and commissioning time and costs can be reduced.
