Danfoss VLT Micro Drive Control Panel with Potentiometer

SKU: 132F Category:

Extend motor life and reduce maintenance cost on AC motors with the Danfoss VLT Micro Drive FC 51 VFD. A Variable Frequency Drive (VFD) controls the motor’s start and speed. It lowers the startup torque and surge by starting the motor at a reduced amperage. Every motor should have a VFD to make it run smoother and last longer. A VFD also improves motor efficiency by 30% on average and minimizes motor repair and maintenance.

Small but Powerful

The VLT Micro Drive FC 51 is small but powerful and built to last. Panel space can be saved and installation costs reduced thanks to its compact size and minimal commissioning requirements.

No Job Too Big

Despite its compact size and easy commissioning, the VLT Micro Drive can be set up to perform perfectly even in complex applications. It is supported by guided programming of specific functions and the use of a PC software tool for parameterizing. And, thanks to its coated PCBs, the drive ensures reliable and cost-effective operation also in demanding environments.

Benefits of Using a VFD on a Crane

  • Fine-Tune Speed Adjustment to Optimize Workspace
  • Improve Load Control
    • Eliminate the jolt and shock of starting or stopping a single speed crane. A VFD will allow a smooth start and stop and will minimize load swings.


  • Side-by-side mounting without derating is possible thanks to the compact, book-style design.
  • Penetration of dust is minimized thanks to coated PCBs.
  • Radio disturbance from motor cables is limited due to built-in RFI filters.
  • Lifetime of the drive is extended and reliability improved as a result of the effective heat sink that removes heat from the electronics.
  • Energy consumption can be reduced as kinetic energy in the application can be transformed into braking power to slow down the motor.

Applications for VLT Micro Drive FC 51

Customers have used the VLT Micro Drive FC 51 in a variety of applications to make work systems more productive by increasing the lifetime of AC motors and to minimize downtime forced by equipment repair and maintenance. Most of our customers have installed the VLT Micro Drive FC 51 on overhead bridge cranes but it can also be used on conveyors, fans, mixers, extruders, pumps, palletizers, packing machines, and other industrial appliances. Depending on the industry VFDs are also called adjustable speed drives, AC drives, micro-drives, and inverters.

How a VFD Works

A VFD is a type of AC motor controller that drives an electric motor by varying the frequency and voltage supplied to it. It can be programmed to function for specific application to improve precision and efficiency in the workspace.

1 review for Danfoss VFD VLT Micro Drive FC 51

  1. Arlen Flanagan (verified owner)

    Danfoss VFD’s are extremely reliable with built in capabilities to operate on three phase or single phase. The RS485 communication allows for full control with a 2 wire connection.
