FR-A800 Series
FR-A800

Product Details

 

The A800 Series is Mitsubishi Electric's flagship inverter solution that delivers multi-use performance, accuracy and system flexibility in a ultra reliable hardware package designed for industrial use.

  • High Speed Response: With a speed response of 50Hz, A800 to respond to a change in motor load. A800 reacts to a speed signal much faster too - between 2 to 3 ms as opposed to 5 to 20 ms with A700.
  • Wide Speed Range: 200:1 speed range open loop, 1500:1 closed loop speed range.
  • Extended Maximum Speed: A standard A800 VFD can drive high speed motors at up to 590Hz, compared to the A700's 400Hz.
  • IPM Motor Control: Standard A800 VFDs can drive the new generation IPM (Internal Permanent Magnet) motors, such as the Marathon 'SyMAX' series.
  • Safety Stop: A800 is a SAFETY drive. "STO" capability enables SIL2 / PLd category emergency stops.
  • Compatible with USB stick: VFD settings can be easily uploaded or downloaded and 'black box' operating data at the time of a drive trip can be copied for diagnosis using the FR-Configurator software.
  • GOT interface: Automatic connectivity to GOT 2000 series GOTs without the need to change any parameters.
  • Improved PLC: A800 has a new internal PLC based around the Mitsubishi 'L series' processor. Instructions in the form of 'Function Blocks' can now be used.
  • Conformal Coating: All A800 VFDs have Conformal Coated boards as standard.

FR-F800 Series
FR-F800

Product Details

 

The F800 Series is a VFD range which has been optimized for maximum energy savings with pump and fan control. F800 is equally at home in an industrial environment or in the residential / commercial sector as part of an integrated HVAC solution.

  • NEMA 1 / UL-1 rated: F800 is Plenum-Rated and can be mounted as a stand-alone unit when required - no need to provide a separate enclosure*
  • Built-in BACnet MS/TP or Modbus RTU communications capability for simple integration into HVAC communication networks
  • Built-in filter to limit the effects of radio noise on sensitive equipment
  • Built-in PLC allows the drive to be customized to individual requirements and can avoid the need to have a separate master controller
  • Optimum Excitation Control. F800 uses vector drive technology to calculate motor load and ensures maximum energy savings, even if motor loading changes
  • 3 programmable skip frequencies - avoid points of mechanical resonance in ducting and pipework.
  • Drive settings can be uploaded or downloaded using a standard USB memory stick
  • Real-time clock. Drive trip messages are 'time stamped' for diagnostic purposes **
  • Bi-Directional Coasting Motor Restart - F800 can safely 'catch' and control a motor which is already spinning (in either direction) on start-up.
  • Advanced PID control features :
    • 2 Independent PID loops
    • Pre-Charge Mode
    • Sleep Mode
    • Multiple Motor control (up to 4)
    • Selectable response to 'loss of signal'
  • Control of high efficiency IPM motors
  • Advanced Power Monitoring capability including pulse train output
  • UL - approved rating for single phase operation (coming soon)
  • Out-of-range warning system detects broken drive belts and other potential mechanical problems

Notes:
* Drive Sizes up to 40HP
** Requires the use of the FR-LU08 keypad
