FR-F800 Overview

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.

• Optimum excitation control for reducing energy consumption - We have adopted and perfected optimum excitation control to ensure that the energy-saving effects are realized during constant torque as well as during the motor’s acceleration/deceleration operations.
• 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
• Extended warranty - MEAU VFD Start-up Service extends standard warranty from 1 to 5 years at no additional cost

As a result of the enhanced optimum excitation control in Mitsubishi Electric variable frequency drives, over current is no longer generated during steep acceleration/deceleration even without limiting the amount of voltage compensation during these operations which ultimately provides improved energy savings.

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.
