FR-E800 PM CONTROLLER FOR HVAC

The FR-E800 permanent magnet (PM) controller is built upon Mitsubishi Electric’s proven variable speed control technology through years of reliable operation across various HVAC applications, including pumps, fans, and compressors. It is designed to save energy, reduce footprint, and minimize cost with advances in quality, performance, and maintenance capabilities.

Key Benefits
  • Compact designs - Compact footprint to control motors up to 10HP, with extension to 30HP by 2021. Mount multiple controllers side by side to minimize enclosure size.
  • Dual overload rating - Light Duty (LD) and Normal Duty (ND) overload current ratings to help achieve the desired performance in smaller frame sizes.
  • Extended environmental rating - Operates in ambient temperature from -20°C to +60°C and conformal coated to withstand harsh environments.
  • Corrosion alert system - World’s first system to identify signs of damage caused by hydrogen sulfide or other corrosive gas. Notifies operators when the production environment needs to be improved and reduces unplanned downtime.
  • Auto-tune to PM motors - FR-E800 provides energy savings when combined with IPM based technology. Our embedded auto-tuning system allows plug and play optimization with many 3rd party IPM motors. This provides quick and easy setup and commissioning without time-consuming ‘tuning” or the need for on-site support.
  • Energy savings - Optimum excitation control reduces energy consumption by removing over current during steep acceleration/deceleration.
  • Power regeneration and harmonic suppression - When paired with the FR-XC multifunction converter one PM controller can handle harmonic suppression and power regeneration. In power regeneration mode, regenerative energy can be supplied to another drive or returned to the power supply in order to save energy.
  • Life diagnostics function - Multiple communication options – Communicate with the drive over a wide range of fieldbus or Ethernet networks

BOOKSHELF-STYLE LAYOUT
When the surrounding air temperature is 40°C or less, multiple inverters may be installed side-by-side to maximize space utilization within the cabinet.

EARLY CLOGGING DETECTION
The speed–torque characteristic under normal operating condition is captured and compared against real time data. When a mechanical fault such as clogging of the filter occurs, the controller outputs a warning or shuts off the output to prevent system damage.

CONTROL BOTH IM AND PM MOTORS
Auto-tune to both IE3/IE4 induction motors and permanent magnet motors via simple parameter setup to increase performance, minimize noise level, and reduce commissioning time.
