0.5 kW single-phase drive for induction and PM motors
The Mitsubishi Electric FR-E820S-0050-4-60 is a Type FR-E800 RS485 inverter rated for 0.5 kW output from a single-phase 240V AC supply. It drives both induction motors and permanent magnet (PM) motors, making it suitable for pumps, fans, and small conveyors in panel builds. Control method selection covers V/F control, real sensorless vector control, PM sensorless vector control, and magnetic flux vector control — the PM sensorless option eliminates the need for an encoder on PM motor retrofits.
Panel fit and commissioning tools
A built-in 4-digit LED display and USB mini-B port allow direct parameter editing and monitoring without a separate programming unit. The 2K program memory supports simple PLC function sequences for standalone logic tasks. Built-in Modbus RTU (RS-485) enables multi-drive networking; the drive is expandable via optional plug-in cards for additional I/O or fieldbus adapters.
Active production with full compliance coverage
Power loss at rated load is 49 W — factor this into enclosure thermal calculations to avoid derating in sealed cabinets. The drive does not support regenerative (4Q) operation, so deceleration energy must be dissipated in a braking resistor or absorbed by the load. This model succeeds the FR-E720S-050SC-EC (order code 234798) with the FR-E800 series platform offering expanded control methods and USB connectivity.
