Mitsubishi FR-F700: the energy saving inverter


Designed for fan and pump applications up to 630kW the Mitsubishi Electric’s F700 variable speed inverter drive offers a wealth of benefits for the user and installer.


The built in energy optimisation software boosts motor efficiency to unprecedented levels and intelligently maximises energy savings during acceleration, deceleration and constant speed operation.  It also calculates and displays your energy savings on its monitor panel either as £s or kW/h, or via your network.
Its windmill start function measures both the speed and direction of rotation of a coasting motor and swiftly and smoothly brings it under control – whichever way it’s spinning.


The ‘power-dip ride-through’ function allows the inverter to continue to run during short power supply interruptions –reducing nuisance tripping. Operation continues without the motor coasting when an instantaneous power failure occurs in fan and blower applications.


Networking is included

Independent RS-485 allows serial communications and keypad operation at the same time with no options needed: as standard F700 supports Modbus RTU as the Mitsubishi Electric protocol.  In addition it supports popular BMS protocols including LonWorks, Metasys N2 and Siemens FLN, plus the industry standards of Ethernet TCP/IP, Profibus DP, DeviceNet & CC-Link.  BACnet MS/TP is built-in.
