Freqrol Inverter 0.75 kW – MITSUBISHI FR-Z024-0.75K
The FR-Z024-0.75K is a variable frequency drive (inverter) from the FREQROL FR-Z series (“Frequency Inverter” / “Variable Frequency Drive”) manufactured by Mitsubishi Electric, rated for 0.75 kW three-phase AC induction motors. The unit belongs to the 200–240 V voltage class and is documented for applications in CNC machine tools and industrial equipment requiring electronic speed control of AC motors. No accessory revisions or documented variants are known; the part number identifies a single nameplate configuration.
The inverter converts fixed-frequency mains power into a variable-frequency, variable-voltage three-phase output, enabling stepless speed control of an AC induction motor. On a CNC machine tool it typically drives auxiliary spindles, coolant pumps, hydraulic units, or other accessory drives. Inverter failure immediately stops the driven device, interrupting the machining cycle or disabling critical machine functions.
Mitsubishi Electric is a Japanese multinational of the Mitsubishi Group and one of the world’s leading industrial automation manufacturers. Its Factory Automation division produces FREQROL inverters, MELDAS / MELDASMAGIC CNC systems, and MELSERVO servo drives. The FR-Z series is legacy / discontinued, superseded by the more modern FR-E, FR-A, and FR-F series; spares are available only as used, NOS surplus, or through specialist repair.
