FR-F800 Series Variable Frequency Drives

The FR-F800 is a pump and fan control VFD optimized for maximum energy saving. Equally at home in an industrial environment or as part of an integrated HVAC system, FR-F800 can also be used as a cost-effective drive for controlling other types of lighter duty constant torque loads.

Key Benefits
• UL-1 design up to 40HP - Convenient installation without an enclosure
• Standard USB port - for simple set-up using a memory stick
• Real-time clock - Enables time stamping of trip messages for easy diagnostics
•  ‘Load detection’ system - Detects broken drive belts and other mechanical problems
• Anti-Windmill function - avoids costly damage to drive and motor by smoothly controlling loads which are already spinning before start-up

Load Detection System
The FR-F800 learns the exact characteristics of any load and speedily detects the unexpected, such as:
                - Broken fan drive belt
                - Motor bearing damage
                - Clogged pipes
                - Blocked filter

Anti-Jamming Feature
The anti-jamming system deals effectively with the problem of starting pumps which have become clogged with debris. A user-programmable sub-routine alternates the pump shaft direction to free the impeller.

Simple Set-Up
The FR-F800 parameters can be entered directly from a standard USB memory stick. Data can be retrieved, copied or edited by means of the FR-Configurator 2 programming package.
