VLT® Micro Drive FC 51

VLT® Micro Drive FC 51

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

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.

Product Range

  • 1 x 200-240 V...0.18-2.2 kW
  • 3 x 200-240 V...0.25-3.7 kW
  • 3 x 380-480 V..0.37-22 kW

VLT® Micro Drive is a genuine VLT®frequency converter with unsurpassed reliability, user-friendliness, condensed functionality, and extremely easy to commission. Terminal numbers are named in the same manner as in the rest of the VLT® family.

Despite the compact size and the easy commissioning, VLT® Micro Drive can be set up to perform perfectly even in complex application set-ups. Approximately 100 parameters can be set to optimize energy efficiency and operation.

Features and Benefits
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.
