What it is and what it does
The Mitsubishi Electric FR-E820S-0110-4-60 is a current-production FR-E800 series inverter designed for single-phase AC input, driving three-phase output to control induction or permanent-magnet motors via V/F control, real sensorless vector control, or PM sensorless vector control. Built-in Modbus RTU on RS-485 and a 4-digit LED display allow direct network integration without an option card, while the onboard PLC function (2K program memory) handles simple sequencing, reducing the need for a separate controller in standalone applications.
Lifecycle and compliance
It directly replaces the earlier FR-E720S-110SC-EC (Mitsubishi order code 234800) and is mechanically and electrically compatible with existing installations — same part, different generation.
