Mitsubishi Electric FR-F800

HVAC Frequency Inverter

Designed for unparalleled energy saving, optimised speed control, simple start-up, and versatility, Mitsubishi Electric has developed a new generation of drive technology: the remarkable FR‑F800.

The FR‑F800 is mainly designed to be used with pumps, fans and compressors and HVAC applications. It features many innovative functions that allow for the best compromise between efficiency and accurate control.


Range of FR‑F800 products

  • 3 x 200-240V 0.75 > 110kW
  • 3 x 380-500V 0.75 > 630kW

Powerful features and intelligent functions

  • Intelligent load detection
  • Pump clean function (de-ragging)
  • Motor preheat function
  • Mechanical resonance suppression
  • Fire override mode
  • Intelligent energy optimisation
  • Autotuning of any IM/PM motor
  • Built in safety function STO
  • Protection of your know-how
  • Easy to start up
  • Built in PLC function
  • Intelligent predictive maintenance
  • Easy system fault diagnosis

Advanced PID controller

At the heart of the FR‑F800 drive is an enhanced PID controller. This means that fan, pump and compressor control is easily handled without the need for external controllers. Furthermore the built-in PLC means true stand-alone capability. Some of the new PID functions are:

  • One drive can control multiple pumps
  • Second PID controller
  • Direct access to PID setpoint via the display
  • Pump Stir function
  • PID output hold (incl. multi-pump)
  • PID upper/lower limit pre-warning
  • Pipe burst detection / Dry run protection
  • Digitally selectable PID setpoints
  • Pipe soft fill to prevent water hammer
  • Water hammer avoidance at stop
  • PID pre-charge function
  • Pre-sleep boost function
  • Automatic PID gain tuning
  • Etc…

Network connectivity

  • CC-Link IE Field interface (FR-A8NCE)
  • CC-Link interface (FR-A8NC)
  • Profibus DPV1 with Dsub interface (A8NDPV1)
  • Profibus DP PPO legacy card (FR-A8NP)
  • Profinet 2-port interface for FR-A/F800 with Drive Profile (A8NPRT_2P)
  • EtherCat (A8NECT_2P)
  • Ethernet-IP 2-port interface (A8NEIP_2P)
  • DeviceNet™ interface (FR-A8ND)
  • Can Open (FR-A8NCA)
  • RS485 communication (Mitsubishi Electric drive protocol, Modbus-RTU protocol, BacNet) is supported as standard.
