Designed for demanding industrial motor control, the Mitsubishi Electric FR-A820-11K-1 variable frequency drive provides exceptional precision and dynamic torque response within the high-performance FREQROL-A 800 series. Operating on a three-phase 200V class input, this unit features flexible multi-rating capabilities (SLD, LD, ND, and HD) to match the exact overload profile of your machinery. Equipped with advanced magnetic flux vector control and real sensorless vector control, it achieves peak torque performance down to near-zero speeds, making it ideal for high-inertia startup applications.

The FR-A820-11K-1 is the direct legacy replacement path for the older FR-A720-11K series. Mounting footprint dimensions remain highly compatible; however, if upgrading from an A720, utilize Mitsubishi FR Configurator2 software to extract and convert the parameter block. Be aware that the A800 series introduces a dedicated 24 VDC control circuit power input, allowing you to maintain communications and safety feedback even when primary three-phase power is disconnected.
When sizing this drive for high-altitude environments, you must derate the output current by 1% for every 100 meters above 1000 meters sea level (up to a maximum of 2500 meters). To prevent nuisance overvoltage trips (E.OV3) during aggressive deceleration profiles, monitor Parameter 8 (Deceleration Time). If short stopping sequences are mandatory, install an external brake resistor connected directly across terminals P/+ and PR, and ensure Parameter 30 (Regenerative function selection) is configured correctly.
To configure analog terminal input behaviors, always verify the status of the voltage/current selection slide switches located behind the control terminal cover. For example, if Terminal 4 is used for a 4-20mA feedback loop, the hardware switch must match the corresponding firmware settings in Parameter 267. Always route your low-voltage control signals through a separate conduit from high-voltage motor output lines (U, V, W) to mitigate electromagnetic interference and potential signal drift.
CRITICAL WARNING: HAZARDOUS VOLTAGE
Isolate all input power connections before mounting or servicing. Wait a minimum of 10 minutes after disconnecting source voltage to allow internal DC bus capacitors to discharge safely. Measure DC voltage across terminal points P/+ and N/-; ensure it is less than 30 VDC before performing physical installation work.
